The KOYO NKS37 is a machined-type needle roller bearing without an inner ring (runs on a hardened, ground shaft or a separate inner ring), for a 37mm shaft (metric series). Machined and ground from solid bearing steel, it has a thick, rigid outer ring that carries very high radial loads and shock in a compact section. Boundary dimensions 37 x 52 x 22mm.
Where no inner ring is used, the shaft must be hardened and ground to serve as the raceway. Suitable for high radial loads in gearboxes, pumps, and industrial machinery. Manufactured by Koyo (JTEKT), Japan.
