Durable even under difficult conditions, NSKs TF Series bearings were created to be long lasting. These bearings have excellent heat, seizure and wear resistance even when exposed to contaminated lubrication.

These bearings are composed of standard bearing steel and were subjected to unique heat treatment processes. The TF, NTF, HTF STF, WTF materials are available as are ball bearings in cylindrical, tapered, angular contact and spherical forms. When used in conjunction with clean lubrication, these devices provide double the service life of competing brands and up to ten times the amount of service life when dealing with contaminated lubrication. This product additionally features a seizure resistance improvement of 40%.
