This double row angular contact ball bearing carries a 20.0 mm bore, 37.0 mm outside diameter and 13.0 mm width, with a net mass of 54.0 g. The design uses a plastic TVH cage and is fitted with seals on both sides, restricting the limiting speed to 10300.0 1/min. The double row arrangement lets the bearing take combined radial and axial loads from both directions within one unit, which suits mounting positions where a single narrow bearing must replace two single row angular contact bearings. The C3 internal clearance compensates for temperature rise during operation, and the integrated seals keep the grease fill in place while blocking contaminants, so no external relubrication is required during service life.
