Spherical washers

Straight bolt tensioning for longer endurance

Vibracon
Vibracon

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

Industrial spherical washers (DIN) consist of a conical ring and a spherical ring resulting in a line contact with a limited load capacity.  SKF Spherical Washers consist of convex and concave rings to create a perfect mating surface and have a high load bearing capacity as result.
