NEXT GENERATION

Originally designed and patented in 1966, Sealmaster® SKWEZLOC® clamp the concentric lock has become the standard in concentric locking and has been redesigned* to accommodate “commercial” grade turned & polished (T&P) shaft tolerances. This new design also provides improved lock reliability on the turned ground & polished (TG&P) shaft tolerances.


SKWEZLOC clamp concentric locking collar clamp design results in near-perfect
concentricity of the shaft-to-bearing bore and maintains near-perfect ball path roundness while reducing fretting corrosion. This design eliminates the shaft damage of setscrew locking and minimizes bearing induced vibration for smoother quieter operation. The collar has a TORX Plus head cap screw that outlasts stripping 12 times longer than hex head cap screws.


NEW DESIGN FEATURES

  • Innovative circumferential groove on the inner ring bore that improves shaft grip and reduces raceway distortion for quieter smoother operation allowing for improved lock reliability.
  • Larger cap screw and collar for improved clamping force to the shaft.
  • Designed for use on “commercial” T&P shafting**, potential user cost reduction on shafting by specifying “commercial” tolerances.
  • Same simple single screw installation, no axial movement during installation or risk of preloading the bearing which is concerns when using an adapter lock design.
  • Patent-pending design.

Note: all values exceed the axial load capacity of the bearing
*In laboratory axial push off testing for 1 7/16”, the next-generation design
resulted in:
- 85% holding force improvement on turned, ground & polish Shafting
vs old design;
- 59% holding force improvement on turned, ground & polish Shaftin
vs leading competitor; and
- 113% holding force improvement on turned & polish shafting vs
leading competitor.




  1. CIRCUMFERENTIAL GROOVE increases inner ring elasticity to improve grip (clamping force) on “undersized” commercial shafting without increasing deformation to inner ring ball path.

  2. LARGER COLLAR & SCREW increase grip and holding power.

  3. OPTIMIZED CHAMFER PROFILE reduces stress concentrations when the collar is tightened.
