Types of Wheel Bearings

Plain Bearing

Simple, well-priced, very solid and usually maintenance-free wheel bearing. For rims or wheels made from polyamide, polypropylen or cast iron no additional bearing bushes are necessary, as these materials good sliding characteristics. For metal rims or similar, plain bearing bushes made from polyamide are used, for heat-resistant wheels specially coated plain bearing bushes can be used optionally.


Heat-resistant, food safe bushes, made from different materials. These bushes are self-greasing, maintenance-free, insusceptible against impact loads. The bushes do not absorb any humidity and are very resistant to corrosion. They are mainly used in the food industry, primarily in heat-resistant wheels. They provide an easy and quiet running of the wheels, unconvenient squeaking is prevented. The bushes are heat-resistant up to 280°C, some even up to 320° C.

Roller Bearing

Robust, resistant and mainly maintenance-free wheel bearings. Roller bearings basically consist of a plastic- or steel cage with steel rollers. A roller bearing has a considerably lower rolling resistance as a plain bearing and therewith the wheel runs easier. Roller bearings are the commonly used bearings for usual transport equiment with medium loading. Roller bearings are also available in a stainless version.

Ball Bearing

Single track groove ball bearings are the ideal type of bearing for all wheels which have to have a high load-capacity and good rolling qualities. These bearings consist of hardened balls inside a ball race that roll between a hardened inner and outer ring . As dust protection for the balls there is a metal disk (Z-bearing) or one or two contact sealing rings mounted to improve the protection (RS or 2 RS bearings). These bearings are mainly used in high-quality wheels or in heavy-duty wheels. Stainless ball bearings are also available.
