new series of Modules 0.5, 0.8, and 1 spur gears from Quality
Transmission Components features the patented Fairloc®
integral hub fastening system which eliminates marred
shafts. These 20° pressure angle precision gears conform to
JIS N8 Grade standards. These SUS303 stainless steel gears
are identified as the SUSL Series. The Fairloc®
integral hub fastener is the ideal choice where phase
adjustment, timing, position adjustment and frequent removal
of the component are factors in the specific application. In
offers full component support along the entire hub section.
These very cost-effective gears are compact, self-contained
and offer a small gear hub envelope.
These gears are designed to
fit shafts ranging from 4 mm to 10 mm in diameter. They are
stocked with face widths ranging from 5 to 8 mm. Their sizes
range from 14 to 120 teeth.
system consists of two slots that are machined into the 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 socket head cap 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.
