Understanding that there are many components that make up the right caster for your application is an important step. We at Caster Technology strive to make sure that you will have the caster that is right for you, that is why we offer a complete line of bearings designed for specific handling applications and conditions.



Annular Ball Bearing

For applications where maximum rolling ease and quiet operation are needed and best suited for light to medium duty loads. A precision type bearing with machined, hardened raceways, pre-assembled, and the entire unit is mounted in the wheel.


Bronze Bearing

Durable under a wide range of temperature and humidity conditions and is corrosion resistant. It is highly recommended for high heat or wet applications.


Acetal Bearing

Extremely durable under a wide range of temperature and humidity conditions, as well as is corrosion resistant. Acetal bearings are well suited for applications where brine conditions, steam cleaning, or where excessive water or liquids are present. Available in one-piece or two-piece.


Caged-Style Roller Bearing

Consisting of a steel cage that provides inward retention of the needle rollers, this design provides maximum cage strength consistent with long service life. Must be used with a hardened spanner bushing or hardened shaft.


Plain & Sleeve Bearing

Only recommended when rolling ease is less critical, this provides a metal sleeve inserted in a wheel to rest directly on the axle.


Precision Sealed Ball Bearing

Recommended for maximum rolling ease with no maintenance lubrication required, this quiet operating bearing is for medium duty to heavy-duty loads.


Precision Tapered Roller Bearings

These bearings are ideal for heavy duty and power-towed caster applications.  These bearings utilize tapered faces designed to handle a combination of downward as well as side forces.


Roller Bearing

Capable of carrying a greater load than the same size diameter ball bearing, it has a split outer race shell into which the roller assembly is inserted. Combination seal/thrust retainer washers protect the bearing from dirt, water, and chemicals. They also help absorb thrust friction. Must be used with a hardened spanner bushing or hardened shaft.


Spanner Integrated Precision Sealed Ball Bearing

Excellent rolling ease with no maintenance lubrication required. Integrated spanner bushing makes installation easy.
