Delrin, a DuPont engineered plastic, is extremely durable under a wide range of temperature and humidity conditions, and is corrosion resistant. Wheels with Delrin bearings are well suited for applications with brine conditions, steam cleaning, or where excessive water or liquids are present. One piece or two piece Delrin bearing models are available (shown with spanner bushing).
Plain and sleeve bearings provide a metal sleeve inserted in a wheel to rest directly on the axle. This option is only recommended when rolling ease is less critical.
Annular ball bearings are precision type bearings with machined, hardened raceways. This bearing is for applications where maximum rolling ease and quiet operation are needed and best suited for light to medium duty loads. The bearing is pre-assembled, and the entire unit is mounted in the wheel.
The bronze bearing is durable under a wide range of temperature and humidity conditions and is corrosion resistant. It is highly recommended for high heat or wet applications (shown with spanner bushing).
Recommended for maximum rolling ease with no maintenance lubrication required, this quiet operating bearing is for medium duty to heavy duty loads.
The roller bearing is 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. Standard Colson roller assembly features hardened steel rollers enclosed in a thermoplastic case on 1-1/2″ and 2″ tread width wheels. Metal cage roller bearings are available (Specify WB29) and are standard on wheels with tread widths of 2-1/2″ and larger. Combination seal/thrust retainer washers protect the bearing from dirt, water, and chemicals. They also help absorb thrust friction (Note: roller bearing must be used with hardened spanner bushing or hardened shaft).
Excellent Rolling ease with no maintenance lubrication required. Integrated spanner bushing makes installation easy.
Torrington-style caged drawn cup bearings have a steel cage that provides inward retention of the needle rollers. This design provides maximum cage strength consistent with long service life. This bearing is available on 2″ tread width wheels only. (Note: Must be used with hardened spanner bushing or hardened shaft.)
