A focus on technology in all our standard ranges

Cage technology
Our cages are made from resin polyamide for the best price/performance ratio: they are lighter and quieter as a result of the optimised geometries.

T2: cage in innovative and high performance polyamide resin for precision angular contact ball bearings for machine tools. It allows rising temperatures to be lowered to reach higher speeds.
T6: PEEK cage, light and sturdy, specially designed for spindle bearings on cylindrical rollers Its design and ability to store grease allows to reduce heat generation and therefore reach higher speeds.
T9: latest innovation from NTN-SNR to go faster at the lowest cost
And we also offer:

T1: cage in phenolic resin for high speed angular contact ball bearings capable of maximum speeds.
Special steels: 2LA - 2A
Increased performance: optimisation of the purity of the steel and special heat treatments
Longer useful life: essentially under very high temperatures at very high speeds
Improved performance: resistance to wear and anti-seizing properties
Internal designs optimised for ultra high speed and top ranges
NTN has developed ultra high speed and top ranges by working on the internal designs and technologies of cages.

Radial angular contact ball bearing – super precision, high or ultra high speed
Cylindrical roller bearings – high precision and ultra high speed
Each application has an optimum preload
4 levels of standard preload: extra light (GL), light (GN), average (GM), strong (GH)
And specially preloaded on request
Hybrid versions with ceramic balls, optionally throughout the entire range
These hybrid versions boost the performance of our bearings and those of your machine tools: speed (+30%), rigidity (+10%), useful life (x3)
