GQZ 7208 Single Row Open Angular Contact Ball Bearing 40×80×18mm Suitable For Duplex Paired Installation
7208 is single row open angular contact ball bearing. It can withstand combined radial load and unidirectional axial thrust. This bearing is commonly arranged in duplex sets including UA universal match, DB back-to-back and DF face-to-face configurations to balance opposite axial forces. Multiple contact angle versions optional: C(15°), AC(25°), B(40°). Open design facilitates re-lubriion and routine maintenance. Widely used on industrial gearboxes, screw compressors, centrifugal pumps, machine tool spindles and medium-high speed rotary machinery.
