Wheel Bearing Types

Wheel bearings reduce the friction between the wheel and axle making your equipment easier to push. When selecting the appropriate wheel bearing for your application, the environment must be taken into consideration. Shields and seals can be supplied with some roller and ball bearings, prohibiting debris from fouling the bearing.

• Plain Bearing: With plain bearings, the wheel rides directly on the axle. This is the least expensive type of wheel bearing and should be selected only for very light equipment or when cost is a more important consideration than performance.

• Sleeve Bearing: With a sleeve bearing, the wheel revolves on a smooth sleeve to reduce friction. This is an inexpensive, quiet and strong type of bearing. Sleeves are available in hardened steel, as well as plastic and stainless steel for use in corrosive applications.

• Ball Bearing: Ball bearings greatly reduce the amount of friction and provide excellent rolling ease. There are many types of ball bearings used in caster wheels - give us a call and we'll help you choose the right one based on your load and performance needs.

• Precision Ball Bearing: This is the best ball bearing type available. The precision ball bearing offers the greatest rolling ease for carrying heavy loads and has a long lifespan. This smooth, quiet running bearing is the right choice for expensive or heavy medical equipment.

• Roller Bearing: Roller bearings offer great rolling ease and can carry heavy loads. These bearings always revolve on a hardened sleeve and require relubrication.
