SKF Spherical washers

Spherical washers from SKF are designed to create an exact, parallel plane between the bolt head and the face of the nut. These washers automatically adjust and compensate for the angular deviation between the planes and prevent the bolt from bending.

Product characteristics:

  • Automatically compensates for angular errors
  • Evenly distributed bolt tension
  • Reduces bolt fatigue from bending bolts
  • Improved bolt stretch possible due to increased clamping length
  • Surface treated for protection in humid and harsh environments
  • Available in standard and low-profile (LP) versions
