Legend
A – Shaft remains smooth
B – Self-contained
(no additional inventory)
C – Component is fully supported
D – Easy adjustment
E – Can be pinned if desired
• Full Use Of The Bore
Gives maximum support to the component,
reduces wobble or misalignment.
• Easy Adjustment
Fairloc® replaces set screws and clamps,
eliminates marred shafts; components can
be repositioned with a single hex key adjustment.
• Compact, Self-Contained Design
When available space or access is limited,
Fairloc's® small hub envelope is a distinct advantage.
• Very High Reliability
Typical Application
Areas For Fairloc® Include:
Computer Tape Drives, Aerospace Components,
Aircraft Instrumentation, Aircraft Fuel Control
Systems, Machine Tools, N/C Machines, Computer
Input / Output Systems, Military Fire Control Systems,
Medical Equipment, Business Machines,
Optical Equipment, Power Drives.
Here's How It Works!
Two slots are machined into the hub,
one oriented radially, the other angularly,
to create a transverse wedge which
remains attached to the solid portion of the
hub on one side. The resultant cantilevered
clamping section has a tapped hole to
accept a cap screw which passes through
a clearance hole in the solid portion of the
hub, and into a threaded hole in the
transverse wedge section. As the screw
is tightened, the cantilevered section
clamps the shaft securely. The screw
can be tightened and released repeatedly
without marring the shaft or affecting
its torque transmitting abilities.
Proved Most Effective
For precision application – Lab tests
proved Fairloc® to be superior to all other
comparable fasteners. For high torque
application – Torques up to 400 lb.in.
are obtained with a 5/8" bore Fairloc® hub.
