Product Description

Super Precision Angular Contact Ball Bearing Single Row Spindle Bearing B71821

 

Description & Applicaitons

1) Machine tools and other precision applications require superior bearing performance. Extended speed capability, a high degree of running accuracy, high system rigidity, low heat generation, as well as low noise and vibration levels are just some of the challenges.

 
2) Rolling bearings for general industrial applications can only partly fulfill these requirements. Therefore, We manufacture a comprehensive assortment of super-precision bearings. Theses super-precision bearings help original equipment manufacturers and end users to further optimize performance parameters of their equipment and applications.
3) The benefits differ depending on the bearing series and applications but include high speed and load carrying ability, long bearing service life, long maintenance intervals and low energy consumption.
Typical applications for super-precision bearings are:
  • metal cutting and woodworking machinery spindles
  • other machine spindles (e.g. balancing machines)
  • high speed rolling mills
  • printing machinery
  • precision ball screws
  • live centres
  • high speed turbochargers
  • vacuum pumps
  • racing cars
  • boat gyrostabilizers
  • machine components for the semiconductor industry

Features:

  • superior bearing performance
  • extended speed capability
  • high degree of running accuracy
  • high system rigidity
  • low heat generation
  • low noise and vibration levels
