A caster wheel 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 include a wheel, facilitating the installation of wheels on objects. Casters are available 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.
Caster wheels are abrasion resistant. Not so much effort is necessary to start rolling it. These wheels are exceptionally long-wearing, built for high capacity applications and have the ability to withstand extreme heat.
The intelligent tracking is mainly used for the two drive, obstacle avoidance, remote control cars, can rotate 360 degrees of freedom

Caster wheel design
Mount: Casters mount equipment or carts in three common manners. A caster top plate allows the caster to bolt the underside of the equipment. A caster stem may screw into place or ‘snap’ into place. Casters may also have a bracket allowing the caster to mount to vertical panels.
Swivel head: A rigid caster allows single back and forth direction. A swivel caster allows for 360-degree directional movement. The swivel action of a caster depends on bearings and lubrication. Bearing designs include ball bearings and raceway bearings. Grease fittings serve to inject grease into the axles, caster raceways and wheels.
Yoke: The part of a swivel or rigid caster is a frame. The caster yoke serves to hold the wheel in place. The yoke, working with a swivel head allows the caster wheel to operate in a 360-degree manner. Other names of the yoke are the fork, rig or housing.
Spring mechanism: Certain casters serve a shock absorbing or vibration dampening function so there needs to be a spring mechanism in the caster design. The typical spring mechanism is a coiled steel spring. There are also hydraulic and elastomeric springs.
Wheel: Caster wheel materials include elastomers (rubber and polyurethane), phenolic, nylons and even steel. There are numerous grades of all of these materials. The proper wheel selection depends on application factors such as floor conditions, load, rollability, speed, and climate.
Wheel bearings: Most caster applications require the wheel to function with a bearing. There are numerous bearing options depending on the wheel design and the application. Common bearings for caster wheels include roller bearings, tapered roller bearings, ball bearings, precision ball bearings, Delrin and self-lubricating sleeves.
Axle bolt and nut: The axle bolt locates the wheel into the caster yoke. The nut secures the axle to the yoke. In some applications, the axle bolt and nut may be hardened or zinc plated for corrosion resistance. It also can be of stainless steel
Caster wheel application
- Load capacity (the total load applied to the casters)
- The number of casters to be used on the equipment (usually four or six casters)
- Floor type (concrete, steel, linoleum, carpet, etc.)
- Floor condition (are there cracks, bumps, unlevel floors?)
- Environment (is the equipment operating at high temperatures, wet or humid conditions, etc.)
- Floor cleanliness (are the floors clean or contain debris such as metal chips, grease, gravel, etc.)
