Pulleys incorporate fastening system
The A6H3 series of pulleys is available from off the shelf stock in double, single or no flange styles.
Stock Drive Products has released the A6H3 series of pitch timing belt pulleys for 3/8-inch wide belts that feature the 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

Adapters save on special shafting
Stainless-steel shaft adapters are high-precision devices with tight tolerances on bores, shank and bore/shank concentricity.
Magnetic attraction for clutches and couplings
Devices feature no friction or wearing parts, use no electricity and have no magnetic particles to leak.
It is compact, self-contained and offers a small pulley hub envelope.
The Fairloc system consists of two slots that are machined into the aluminium 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 economy of the over-moulded black fibreglass re-inforced Polycarbonate pulley, plus the positive fastening characteristics of metal-to-metal contact.
The A6H3 series of pulleys is 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-inch in diameter.
The number of grooves per pulley ranges from 10 to 72.
