Split-Tapered Bushing-Bore Sprockets for ANSI Roller Chain
Since these sprockets grip bushings more tightly than taper-lock sprockets, they’re often used in high-torque applications. The same sprocket can be used with different shaft diameters; choose a compatible split-tapered bushing with the bore size you need.

Metal Worms and Worm Gears
Worm gears use screw threads to make large reductions to shaft speed while transmitting motion at a right angle. They transmit motion from worm to gear and cannot be reversed. For gears and worms to mesh correctly, they must have the same pressure angle and pitch/module. These worms are compatible with plastic worm gears.
Speed ratio is the ratio by which output shaft speed is reduced. As speed decreases, torque increases.
Cast iron gears are strong and durable.
