The IKO KT283327 is a needle roller and cage assembly (KT series) for a 28mm shaft. Precision needle rollers are held and guided by a one-piece cage that spaces them evenly, giving high radial load capacity and accurate, low-friction running in the smallest possible radial section. Boundary dimensions 28 x 33 x 27mm.
The assembly has no inner or outer ring – it runs directly on a hardened and ground shaft (raceway diameter Fw) and housing bore (Ew), so it needs the least radial space of any needle bearing. Operating temperature range approximately -20C to +120C. Manufactured by IKO (Nippon Thompson), Japan, to JIS precision standards.
