After weeks of home improvement projects, our apartment's floors had become dirty with an assortment of debris, half of which seemed to have found itself stuck onto the caster wheels. Combine that with the normal amount of dust and pet hair that accumulates on the floor, and it's no wonder my task chair wasn't rolling smoothly. It was time to get cleaning! Follow the instructions step by step above via slideshow, or with all images at once below.Here's our Steelcase Leap chair's caster wheels. They look pretty nasty, with bits of paint, dirt, and other things we couldn't identify (nor would want to know).

2. Just in case you needed more proof, here's a close up. 3. Supplies you'll need: drop cloth or plastic sheeting, screw driver, rubbing alcohol, surface cleaner, cloth or paper towel, cotton swabs/Q-tips, scrub brush, vacuum (not pictured). 4. Protect your floor with the drop cloth before starting so what you clean off doesn't end up spoiling your floor, carpet or rug beneath.white desk chair swivel 5. Flip your chair for better access to the caster wheels.buy online resting chair 6. Use a scrub brush to remove the majority of debris stuck onto the wheels. discount teak dining chairsWe like to follow up a second time with the brush slightly soap-dampened; deck chair hire north west

this removes additional material, while also softening up some of the more stubborn debris for the next step. 7. Here you can see the majority of foreign material has been removed just with the brush, but some gummed up material is stubbornly holding on. 8. Bust out the butter knife for stuck-on stubborn material. Angle your knife nearly parallel with the wheels, holding it steady, but "slicing" in the same directions as the wheels spin. where to buy ghost chairs in torontoSpreading onto toast afterward is not recommended.outdoor chair cushions clearance australia 9. Gummy debris has been removed, but alas, there's still more stuck inside the wheel.cheap rocking chair pad 10. Next, we vacuum any hair, dust or pet hair caught inside the wheel. wood rocking chair kits

This Dyson pet vac sucked up so much hair, we practically had another small kitten's worth inside the dust receptacle! 11. For a very thorough cleaning, we removed the wheel from the base. This may require the use of additional tools like a wrench or screw driver, depending upon your model. Our wheel popped out with a little bit of elbow grease. 12. First using a surface cleaner spray onto a dampened wash cloth, then followed with some rubbing alcohol applied to cotton balls, we clean each wheel thoroughly inside and around of any remaining debris. queen anne chair ebayThe rubbing alcohol is especially good at cleaning and creating a very dry and smooth surface. If you've got any spray lubricant on hand, this is a great opportunity to add a little to the wheel mechanism.Now your wheels should make less noise and you've extended the life of your chair and the floor underneath. Take your chair out for a spin and congratulate yourself for a job well done.

Additional Notes: Before returning your newly cleaned task chair, be sure to vacuum, and wipe clean the area on which your task chair normally resides. All that hard work would be wasted if you were just to return it back to a dirty surface! Want more smart tutorials for getting things done around the home?

A b (also i according to some dictionaries [1] [2] ) is a wheeled device typically mounted to a larger object that enables relatively easy rolling movement of the object. Casters are essentially special housings that includes a wheel, facilitating the installation of wheels on objects. Casters are found virtually everywhere, from office desk chairs to shipyards, from hospital beds to automotive factories. They range in size from the very small furniture casters to massive industrial casters, and individual load capacities span 100 pounds (45 kg) or less to 100,000 pounds (45 t).

Wheel materials include cast iron, plastic, rubber, polyurethane, forged steel, stainless steel, aluminum, and more. Casters comprise two major categories: a swivel caster pivots around a kingpin, so it rotates as well as rolls, while a rigid caster has its wheel mounted in a fixed frame, or rig, and only rolls. This type of caster allows for movement in multiple directions. They can have one or two sets of raceways that allow the caster to swivel 360 degrees under a load. The different types of swivel casters include the following: This style of caster only allows forward and backward movement. Rigid casters tend to be stronger than swivel casters. They are rated at the same capacity as the swivel casters for safety reasons. They can be a one piece construction or a two piece construction that is riveted or welded. The key dimensions to consider when determining the proper type of caster and caster size for a particular type of equipment and application are its overall height, swivel radius, and swivel offset (see Caster Dimensions diagram).

The key elements of a caster include the following: Casters are available in a large selection of various rigs and yokes, wheel materials, swivel offsets, and wheel configurations. In many cases, it can become extremely difficult to choose the right caster for the application. In order to help the user to determine the right caster to use, it's important to take a couple of factors into consideration, which include: Many casters are specifically designed for each of the following applications. Typical caster found on an office desk chair. Casters can be designed to meet the ergonomic needs of an industrial or automotive plant setting, which typically means floor conditions can range from being relatively clean, to having some debris. For these applications, casters can be designed using a variety of wheel materials, including thermoplastic elastomers, polyurethane, and soft rubber wheels. Harder wheels, such as the elastomer and polyurethane can be used on smoother concrete plant floors to give easy rolling for plant equipment, and the softer wheels such as those made with rubber, can be used on various floor surfaces with debris.

The increased swivel offset on many rigs can also be designed into the caster to reduce the swiveling force of casters (the force required to turn a caster in the direction of travel). [5] Many industrial casters are also designed with multiple wheels to allow for an increased load capacity to be handled by the equipment. Multi-wheel swivel caster used in heavy industrial applications A broad range of industrial applications require the movement of large, heavy objects. Aerospace is one such category, in which large airframes or engine parts are moved throughout manufacturing plants. Casters in these plants are high capacity, with load limits of several tons each or more. The caster wheels must be robust, and are normally forged steel, nylon, or metal with a polyurethane tread. In some cases they may be pneumatic or solid rubber, and the casters may be multi-wheel (i.e., having two or more wheels per caster). Casters used in and around furnaces and ovens must withstand extreme heat.

General purpose casters cannot survive excessive heat because tread materials, lubricants and other critical components can fail. For example, at 200 degrees F, common resilient tread materials are at or above their functional temperature limits. High temperature casters employ special lubricants and materials that can withstand higher heat. Additionally, for very high temperatures, special sleeve bearings may be used that have no lubricant whatsoever. Casters are widely used in the medical industry for applications such as hospital beds, equipment carts, surgical tables, and IV poles. Medical casters must tolerate exposure to the various cleaning and disinfectant fluids used in hospitals. Hospital beds and stretchers are typically equipped with a central caster locking system that allow all casters to be simultaneously locked by one person. Medical equipment casters must often have high load capacities, with low profiles and swivel resistance, to accommodate high patient or equipment weight while providing ease of operation over different floor types and through tight spaces.

Safety and reliability are paramount for casters that support (e.g., hospital beds) patients. Consequently, medical casters are subject to industry requirements such as ANSI, BS EN12531, [6] and IEC 60601. The primary example of the benefits of using casters is to reduce the risk of workplace injuries for its users, particularly overexertion. Overexertion [7] occurs when the caster being used is not suited for the application, mainly due to the wrong wheel material or rig, causing injury to the user. There are many health and safety organizations that enforce and regulate the allowable forces and noise levels that casters can make on a plant floor, and include the Canadian Centre for Occupational Health and Safety (CCOHS), Occupational Safety and Health Administration (OSHA). For example, CCOHS recommends that the maximum horizontal force someone should exert is 50 lbf. [8] Liberty Mutual has also produced a Snook Table that provides the percent population of male and female able to push at a given horizontal force.

[9] This force can be adjusted to a safe level by providing the right caster wheel material and rig. To ensure the design integrity of casters, the Institute of Caster and Wheel Manufacturers [10] (ICWM) working in collaboration with the American National Standards Institute (ANSI) has developed the ANSI ICWM: 2012 The ICWM Performance Standard for Casters and Wheels [11] which is intended to provide manufacturers, specifiers and users with a common basis for evaluating the safety, durability, structural adequacy and technical requirements for group specific casters and wheels. One major disadvantage of casters is flutter. A common example of caster flutter is on a supermarket shopping cart, when one caster rapidly swings side-to-side. This oscillation, which is also known as i, occurs naturally at certain speeds, and is similar to speed wobble that occurs in other wheeled vehicles. The speed at which caster flutter occurs is based on the weight borne by the caster and the distance between the wheel axle and steering axis.

This distance is known as trailing distance, and increasing this distance can eliminate flutter at moderate speeds. Generally, flutter occurs at high speeds. What makes flutter dangerous is that it can cause a vehicle to suddenly move in an unwanted direction. Flutter occurs when the caster is not in full contact with the ground and therefore its orientation is uncontrollable. As the caster regains full contact with the ground, it can be in any orientation. This can cause the vehicle to suddenly move in the direction that the caster is pointed. At slower speeds, the caster’s ability to swivel can correct the direction and can continue travel in the desired direction. But at high speeds this can be dangerous as the wheel may not be able to swivel quickly enough and the vehicle may lurch in any direction. Electric and racing wheelchair designers are very concerned with flutter because the chair must be safe for riders. Increasing trailing distance can increase stability at higher speeds for wheelchair racing, but may create flutter at lower speeds for everyday use.

Unfortunately, the more trail the caster has, the more space the caster requires to swivel. Therefore, in order to accommodate this extra swivel space, lengthening of frame or extending the footrests may be required. This tends to make the chair more cumbersome. Caster flutter can be controlled by adding dampers or increasing the friction of the swivel joints. [12] This can be accomplished by adding washers to the swivel joint. The friction increases as the weight on the front of the chair increases. Anytime the caster begins to flutter, it slows the chair and shifts weight to the front wheels. There are several online anti-flutter kits for retrofitting wheelchair casters in this manner. Other methods of reducing caster flutter include increasing swivel lead, using heavier grease, reducing the mass of the wheel, or increasing friction with the ground by changing materials. Casters are also stopped completely using caster cups. ^ 12 Making the Front Wheels, Center for International Rehabilitation Chapter
