Transmits axial load in one direction only, separating into two washers and a ball-and-cage set with a steel sheet metal cage (JP). Overall height is 24.0 mm, net mass 0.304 kg, limiting speed reaches 4850 1/min and reference speed 8200 1/min. This deep groove ball bearing is designed for single-direction axial loading and must not be operated under radial load. The pressed steel cage keeps the assembly light while guiding the balls at the stated speed ratings; shaft and housing washers should be mounted with correct alignment to the direction of thrust. Equivalent designations: SKF 51307, NSK 51307, NTN 51307.
