Spherical Roller Bearings
  1. Increase Load Rating
  2. Longer Operating Life
  3. Low Noise
  4. High Temperature Lasting (up to 200 Celsius)

  • Suitable for application where misalignment can arise from error in mounting or from shaft deflection.
  • Extremely high radial load capability because of the line contact to the rollers and raceway.
  • Wide array of product line : from ID 25mm , 0ver OD 1000mm
  • Easy mounting and dismounting by tapered bore.
  • Press fitting adapter sleeves make internal clearance adjustment.
