Spherical roller bearings are double row, self-retaining units comprising
solid outer rings with a concave raceway, solid inner rings and barrel rollers with cages. The inner rings have cylindrical or tapered bores. The symmetrical barrel rollers orient themselves freely on the concave outer ring raceway. As a result, shaft flexing and misalignment of the bearing seats are compensated.
Sealed spherical roller bearings are characterised by: - very high basic dynamic and static load ratings; - lower frictional torque compared to the competition; - environmentally friendly characteristics; - lower grease consumption and disposal costs; - no requirement for expensive relubrication systems; - reduced maintenance outlay; - simple reconditioning of series 240 and 241; - longer operating life of the bearing. Sealed spherical roller bearings are suitable for areas of operation such as continuous casting plant, conveyor belts, elevator plant or the food industry.
