This bearing carries axial loads in one direction only, transferring force through two flat washers and a ball-and-cage assembly with a steel sheet metal cage (JP). Overall height is 11.0 mm, net mass 55.0 g, limiting speed 9700 1/min and reference speed 9500 1/min. It is a deep groove ball bearing, symbol 51105, made by FAG. Single-direction axial loading means the shaft and housing washers must remain aligned under load, as the design does not accommodate radial forces or misalignment between rings. The steel sheet metal cage keeps ball spacing stable at the stated speed range, and the open construction requires separate sealing and lubrication provisions to be arranged externally at installation. Dimensionally and constructionally equivalent parts are available as SKF 51105, NSK 51105, and NTN 51105.
