This bearing carries axial loads acting in one direction only, transmitting them through a set of balls guided by a steel sheet metal cage (JP design). The design height is 31.0 mm and the net mass is 0.936 kg. The limiting speed is 3550 1/min, while the reference speed reaches 6400 1/min, giving a margin between thermally safe operation and the mechanical speed limit of the cage and raceway design. Being a single-direction deep groove ball bearing, it must be mounted with the shaft and housing washers correctly oriented and supported against axial displacement only from one side, without capacity for radial load. The steel sheet metal cage keeps the assembly light and suited for moderate speed ranges within the stated limits. Dimensionally and constructionally equivalent to SKF 51310, NSK 51310, and NTN 51310.
