Set Screw Locking Distorts the Inner Race and

Introduces System Eccentricies

The Skwezloc® Advantage

Skwezloc Maintains Shaft Centrality

Set Screws Distort the Shaft and Create Unbalanced Load

TORX Head Cap Screw in the Collar Minimizes Stripping

TORX VS. HEX




TORX Head Cap ScrewOutlasts Stripping

12X Longer Than Hex Head




The Proven Results of Skwezloc are:- Minimal Vibration- Reduced Fretting Corrosion- Silent Operation- Smoother Rotation- Higher Speeds- Locks to Stainless Shafting

Skwezloc Does NOT Mar the Shaftand Therefore Provides:

-Quick Installation-Easy Replacement
