The IKO BA1212Z is a drawn cup (shell type) needle roller bearing with open ends, for a 19.050mm shaft (imperial 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 19.050 x 25.400 x 19.05mm.
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. Use with a hardened shaft or the IRB 812-1 inner ring as the inner raceway. Manufactured by IKO (Nippon Thompson), Japan.
