KHS Spherical roller bearings are double row, self-retaining units comprising solid outer rings with a concave raceway, solid inner rings and barrel rollers with cage. The inner rings have cylindrical or tapered bores. The Symmetrical barrel roller orient themselves freely on the concave outer ring raceway. As a result, shaft flexing and misalignment of the bearings seats are compensated. Spherical roller bearings can support axial forces in both directions and high radial forces, they are designed for very high load carrying capacity and since they have the maximum possible number of large and particularly long barrel rollers are also suitable for the heaviest loads. Due to the narrow osculation between the rollers and raceways, uniform stress distribution is achieved in the bearings.
