High Precision Roller Bearings – ULTAGE

High Precision Roller Bearings – ULTAGE

High Precision Roller Bearings Features

Higher machine efficiency
Thanks to reduced friction, the optimised internal design offers higher speeds. As a result, the performance is extended and the operating temperatures are kept lower.

Lower maintenance cost
Thanks to their dynamic load capacities, among the highest on the market and the optimisation of all constituent parts of the bearing, you benefit from a doubled service life compared to a standard solution, an improved reliability for your installations and reduced operational costs.

Reduced environmental impact
With a solution in compliance with the new environmental challenges, you benefit from less noise, less friction, reduced power and lubricant consumption.

Cylindrical Roller Bearings

Double row: Standard NN (U)49 (K), NN30 (K), High speed NN30 HS (K)

  • Machined brass cage

Single row: N series, High speed HS and Ultra high speed HSR

  • High strength machined brass cage for HS types
  • Special molded resin cage for HSR types
  • Optimised internal designs allow higher speed limits and result in lower temperature rise

Ball Screw Support Bearings
