Bearing Type


In order to improve the rolling, most of the casters will install bearing. There are three kinds of bearing types: precision sealed ball bearing, roller bearing and plain and sleeve bearing.


Precision Sealed Ball Bearing 

Recommended for the product required high rolling ease and for medium duty to heavy duty loads, it is also no maintenance lubrication required.

Roller Bearing

Roller bearing is capable of carrying a greater load than the same size diameter ball bearing.
Combination seal washers protect the bearing from dirt, water, and chemicals.
(Note: Roller bearing must be used with steel outer shell for protection and add the rolling ability)

Plain and Sleeve Bearing 

Plain and Sleeve bearings provide a metal sleeve inserted in a wheel to rest directly on the axle. In addition to improve the load capacity, it will help provide the protection and support between the caster and axle. Only recommended for when rolling ease is less critical.



High-quality products must not only control each production process strictly, but also select each part of the caster carefully.
