The KOYO HK0709 is a drawn cup (shell type) needle roller bearing with open ends, for a 7mm shaft (metric series). Its thin-walled, deep-drawn outer shell forms the outer raceway, giving the lowest sectional height of any needle bearing while carrying high radial loads in a compact, economical package. Boundary dimensions 7 x 11 x 9mm.
The open-end (standard) type has a narrow flange gap that helps retain grease and exclude contamination. The bearing is press-fitted into the housing bore, so no axial location fixtures are needed; maximum operating temperature approximately 140C. Manufactured by Koyo (JTEKT), Japan.
