The IKO NA4901 is a machined-type needle roller bearing with its own inner ring, for a 12mm 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 12 x 24 x 13mm.
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 121613. Manufactured by IKO (Nippon Thompson), Japan.
