GQZ 7312 Single Row Open Angular Contact Ball Bearing 60×130×31mm For Paired Installation Configurations

7312 is single row open angular contact ball bearing. It is engineered to withstand combined radial load and unidirectional axial thrust. Normally used in duplex sets (DB / DF / UA) to balance opposite axial forces. Open design supports convenient re-lubriion and maintenance. Widely fitted on industrial gearboxes, large pumps, compressors and medium-high speed heavy-duty rotary equipment.

Formal quotation will be sent within 24 hours upon your inquiry.
