Bearing inserts / Radial insert ball bearings — for flexible mounting options on shafts and in housings

Bearing inserts or radial insert ball bearings are designed for simplified mounting on shafts or in housings. They are designed for high radial and low axial forces. Their design allows them to compensate for misalignments and deflections of the shaft.

Features of this series

Main dimensions according to DIN 626-1. For high radial and low axial loads. Fixing of the inner ring onto a shaft possible. Good compensation of misalignment in case of the use in corresponding housings.

Versions of radial insert ball bearings

Extended inner ring with grub screws (UC 2, UC 3, SB 2, SSUC 2): Fixing of the inner ring onto the shaft by grub screws. Suitable for both directions of rotation in case of moderate loads.
Eccentric collar (SA 2, UEL 2): Fixing by eccentric collar and grub screws onto the shaft. Also suitable for higher speeds at constant direction of rotation.
Conical bore (UK 2, UK 3): Fixing through adapter sleeves onto the shaft makes possible high speeds, changes of direction of rotation and quiet running.
Cylindrical bore (CS 2): Fixing by shaft fitting allows medium to high speeds. Space-saving installation. For higher loads.

Material description of radial insert ball bearings

Radial insert ball bearings made of rolling bearing steel: are economical, withstand extremely high load-ratings and are suitable for temperatures from circa -10°C up to +120°C, in case of rubber seals up to circa +100°C in the long run. The rolling bearing steel is wear-resistant, shock-resistant, conductive and magnetic.
Radial insert ball bearings made of stainless steel: are hygienic, corrosion-resistant, offer high load-ratings, magnetic and are admissible for a temperature range from circa -20°C up to +125°C.
