Wheelchair caster bearing selection

Casters are used in a wide range of applications and are suitable for almost all industries. According to the needs of different industries, people continue to invent various casters, and caster bearings are very important for casters.

There are many types of bearings used in wheelchair casters. Without them, casters lose their value. Therefore, it is recommended that the ideal bearing should be suitable for its respective application and ensure the necessary safety margin. In addition to the wheel surface, wheel diameter and swivel bearing, the wheel bearing determines the mobility of the caster, and even determines the quality of the caster.

There are different requirements for different usage environments. The casters used in wheelchairs for the elderly are different from those used by businesses. The casters used in utility carts are not the same as the light duty casters used in hospital beds. The requirements for casters used in shopping carts must be completely different from casters used in factories to transport heavy loads.

In general, bearings are of the following types:

Roller bearings: Heat-treated roller bearings can carry heavy loads and have average rotational flexibility.

Ball bearings: Ball bearings made of high-quality bearing steel can carry heavy loads and are suitable for occasions that require flexible and quiet rotation.

Plain Bearings: Suitable for high and extremely high loads and high speeds.
