Bearing structure provides its own supply of grease, effective seal, and increased radial clearance has a beneficial effect on the compensation of shaft deflections and thermal deformation. In terms of construction they can be divided into pillow blocks, flange and tension housings.

Self-aligning ball or spherical roller bearings are mounted in housings made of grey cast iron, stainless steel, sheet steel or in thermoplastic housings.

The standard working temperature range from -20°C to   120°C. Owing to its advantages, bearing units are applied in agricultural, construction, mining, textile machines, fans, in the food and wood industry, conveyor systems and transportation devices.
