The Skwezloc® concentric locking design first debuted
in the 1966 and in the early 2000’s, more competitive designs with concentric
locking collars were introduced. These designs require Turned, Ground, and
Polished (TG&P) shaft tolerances.
Concentric Locking Collar has been redesigned
to accommodate “Commercial” Turned and
shaft tolerances with improved lock reliability of TG&P shaft tolerances.
Features of the Next Generation Skwezloc
circumferential groove on the inner ring bore that improves shaft grip
cap screw and collar for improved clamping force to the shaft
user cost reduction on shafting by specifying “Commercial” tolerances
