Long life ball bearing
NTN-SNR

Bearing with special TMB heat treatment: This refers to ball bearings whose original heat treatment enables an increased life at ISO dimensions of 220%. The reduction in the sensitivity of the material to micro-cracks enables either an increased life in a polluted environment (presence of metal particles in the oil, etc.) or a reduction in the size fitted while maintaining its length of life. Applications: electric motors, alternators, vehicle gear boxes, etc.

Bearing with special TAB heat treatment: This refers to ball bearings whose original heat treatment enables an increased life at ISO dimensions of 360%. . The reduction in the sensitivity of the material to micro-cracks enables either an increased life in a polluted environment (presence of metal particles in the oil, etc.) or a reduction in the size fitted while maintaining its length of life. Applications: electric motors, alternators, vehicle gear boxes, etc.
