Acetal spur gears incorporate hub fastener

The S1VZ05M, S1VZ08M and S1VZ10M are 20 degree, pressure angle metric gears that feature the Fairloc integral hub fastener.

Sterling Instrument has released 0.5, 0.8 and 1 Module acetal spur gears which meet ISO Class 7 specs with 303 Stainless Steel hubs.

They feature the Fairloc integral hub fastener.

The S1VZ05M, S1VZ08M and S1VZ10M are 20 degree, pressure angle metric gears.

Fairloc is an integral hub fastener which eliminates marred shafts.

The choice of Fairloc hubs permits frequent phase adjustment, timing and position adjustment while adding positive metal-to-metal fastening strength along both hub sections.

The Fairloc integral hub fastener consists of two slots that are machined into the hub, one 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.

They are stocked in 5mm face widths and are designed to fit shafts that are 5 or 8mm in diameter.

They are stocked in a range of sizes from 15 to 95mm in diameter and with 15 to 186 teeth.

Gears with 10mm bores are stocked without the Fairloc hub.
