HIGH PRECISION BEARINGS:for ultimate performanceHIGH PRECISION BEARINGS:for ultimate performance NTN, your trusted partner for the most demanding applications. Bearings optimized for your machine tools The range of extra precision bearings has been developed by NTN experts in close collaboration with some of the biggest names in machine tools. NTN Precision Bearings Benefits: Productivity: optimized production cost Accuracy: high-quality machining Reliability: reduced maintenance costs Eco-design: environmental protection The range features the ULTAGE® label, proof of its ultimate performance. A wide range of high-precision bearings for all your needs Spindle bearings Angular contact ball bearing – high precision, standard or high speed High precision cylindrical roller bearings with 1 or 2 rows of rollers HTA precision thrust ball bearings Ball screw support bearings BSTU - sealed BST - open/sealed 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 optimized 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 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 optimized 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) Do you have specific requirements?
