Spherical roller bearings

Spherical roller bearings are manufactured in a standard design. Basic bearing designations are indicated in the catalogue datasheets and are in accordance with international ISO and/or GOST standards. The system listed below with suffixes is applied to differentiate design variants. You can get in touch with our services to clarify a bearing design availability, to get additional bearing technical data, which is not listed in the catalogue as well as to discuss with our technical experts your specific requirements for a bearing design.
