Fairloc® Hub Fastening System

Driven Product Finder & Current Prices
 A
new series of 67, 1/5" Pitch timing belt pulleys, for 3/8" wide
belts, manufactured by Stock Drive Products feature the patented Fairloc®
integral hub fastening system. The choice of Fairloc® rotating component
fastening system helps phase adjustment, timing, position adjustment and
frequent removal problems while adding positive metal-to-metal fastening
strength along the entire width of the pulley to reduce wobble or
misalignment. It is compact, self-contained and offers a small pulley hub
envelope.
The Fairloc® system consists of two slots that are machined into the
aluminum hub, one orientated 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. The
design offers the best of both worlds - the economy of the over-molded
black fiberglass reinforced Polycarbonate pulley plus the positive
fastening characteristics of metal-to-metal contact.
Identified as the A 6H 3 Series, they are available from off-the-shelf
stock in double, single or no flange styles. They are designed to fit onto
shafts that range from 3/16" to 3/8" in diameter. The number of
grooves per pulley ranges from 10 to 72. For current prices, look under
