VS Series Spherical Roller Bearings

NSK’s long-life VS series spherical roller bearings are engineered specifically to contend with high speeds, eccentric loads and mechanical shock in vibrating machinery. An optimized internal bearing design with tightly controlled clearance and dimensional tolerances delivers robust capacity and smooth running over a long operating life.

VS Series Spherical Roller Bearings

Design Features

  • Manufactured from ultra-clean steel for optimal fatigue strength and longer life
  • Heavy-duty, precision machined one-piece brass cage
  • Advanced raceway surface finishing for durability and wear resistance
  • Special dimensional tolerances - set at 1/2 relative to the normal - to minimize vibration during operation
  • Special internal clearance - set at upper 2/3 relative to the standard - for optimal operating clearance and reduced heat generation
  • Dimension series 223 and 233
  • For shaft diameters ranging from 40 to 220 mm
  • Available with Hi-TF material option

Operating Benefits

  • As much as twice the service life of conventional bearings in applications subject to frequent vibration
  • High resistance to heavy and shock loads
  • Surface finish minimizes sliding contact in high load zones and facilitates better lubricant film
  • Superior roller guidance and lubricant distribution from machined brass cage
  • High-speed performance with low temperature rise
  • Reduced bearing damage from slippage, surface fatigue and flaking
  • Higher operational reliability - reduced maintenance cost
