Fairloc® Hub Pulleys
Here's How It Works!
Two slots are machined into the hub, one oriented
radially, the other angularly, to create a trans-
verse 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 cantile-
vered 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.
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 Sys-
tems, Machine Tools, N/C Machines, Computer Input / Output Systems, Military Fire Control Systems,
Medical Equipment, Business Machines, Optical Equipment, Power Drives.
