Deep groove ball bearings are manufactured with different variants and dimensions. The catalogue table specifies the basic designations of bearings that comply with GOST and/or ISO international standards. A system of suffixes shown below is used to name different type variants. You may contact our services to determine the availability of specific types, obtain additional product parameters that were not included in the catalogue, and discuss your specific requirements for bearing design with our specialists.

ANGULAR CONTACT BALL BEARINGS

Angular contact ball bearings are available in many designs and sizes. The most widely used designs are: single row and double row 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.
