TAPERED ROLLER BEARINGS

Tapered roller bearings are available in many designs and sizes. Main designs are single row, double row and four row tapered roller bearings. 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.
