Description
Carries axial loads in a single direction only, thanks to its design with separate washers and a ball-and-cage assembly seated between them. The bearing 51309 has a height of 28.0 mm and a net mass of 0.642 kg. The cage is made of pressed steel sheet metal (JP). Limiting speed is 3800 1/min, while reference speed reaches 6800 1/min. Because it supports load in one direction only, correct axial alignment during mounting is required, with the shaft and housing washers positioned according to the load path. The pressed steel cage keeps the assembly lightweight while guiding the balls at the stated speed ratings. Dimensionally and constructionally interchangeable with SKF 51309, NSK 51309, and NTN 51309.
