SKF SMSW Spherical Washers, Standard and Low Profile

SKF SMSW Spherical Washers, Standard and Low Profile

SKF spherical washers create an exact parallel plane between bolt head and nut face, compensating angular deviation and preventing the bolt from bending.

Key features

  • Automatically compensates for angular errors
  • Evenly distributed bolt tension; reduces bolt fatigue
  • Improved bolt stretch due to increased clamping length
  • Surface treated for humid and harsh environments
  • Standard and low-profile (LP) versions
