The IKO NA6905 is a machined-type needle roller bearing with its own inner ring, for a 25mm 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 25 x 42 x 30mm.
The integral inner ring provides a ready raceway so the bearing can mount directly on a soft or unhardened shaft. Suitable for high radial loads in gearboxes, pumps, and industrial machinery. Compatible inner ring: LRT 253030. Manufactured by IKO (Nippon Thompson), Japan.
