Bearing inserts are deep-groove ball bearings for installation in housings and are an economical solution. Bearings with a spherical outer ring compensate for static misalignment of the shaft. The designs differ in terms of their fixing possibilities, holding force and ease of installation. Bearing inserts can be optimized for the application both technically and economically thanks to a wide variety of designs and special properties. S-type bearing Bearing inserts with an eccentric ring are also commonly called S-type bearings . They are fixed in place on the shaft by rotating the eccentric ring and secured by means of a grub screw. The “clamping” results in a slight deformation of the inner ring and therefore higher radial runout accuracy at higher speeds. This design is preferred by European manufacturers, but it is also more expensive because it involves more mechanical parts and costlier processing of the inner ring. These bearings are therefore not suitable for alternating directions of rotation because the eccentric ring on the S-type bearing can more easily become loose. Bearing insert with BPSS BPSS is an abbreviation for "bullet point set screw" and is a refinement of the ball pressure screw. The special design makes self-expansion possible and guarantees a secure fit, even in cases of strong vibrations. At the same time, the inner ring is deformed significantly less as a result of the tightening, meaning that the radial runout accuracy is maintained. Inadequate sealing can allow external environmental conditions to have an extremely negatively impact on running characteristics and thus a bearing’s service life.
