Power Transmission

Spur Gears and Racks

Spur Gears and Racks

The simplest type of gear for transferring motion, with straight, parallel teeth

Miter Gears

Connect shafts at a right angle without changing speed or torque

Worm Gears

Reduce speed while transferring motion at a right angle in only one direction

Bevel Gears

Reduce speed while transmitting motion at a right angle

Ratchet Gears and Pawls

Ratchet Gears and Pawls

Transmit motion in one direction and stop it in the other

Helical Gears

Curved teeth stay in contact longer to transmit heavier loads at higher speeds than spur gears

Drive Sprockets

Drive Sprockets

Mount directly onto a shaft to transmit rotary motion and torque

Timing Belt Drive Pulleys

Timing Belt Drive Pulleys

Pair with a timing belt to keep your drive system in sync

Idler Sprockets

Idler Sprockets

Press against your chain to take up slack and reduce wear and vibration

V-Belt Drive Pulleys

V-Belt Drive Pulleys

Pair with a V-belt to transfer motion from a rotating shaft

Timing Belt Idler Pulleys

Timing Belt Idler Pulleys

Add to your timing belt setup to minimize vibration and keep belts from wearing out

Round Belt Drive Pulleys

Round Belt Drive Pulleys

Mount directly onto a shaft and pair with round belts to transmit rotary motion and torque

Flat Belt Idler Pulleys

Flat Belt Idler Pulleys

Spin freely on built-in bearings to reduce wear and vibration on flat belts

Round Belt Idler Pulleys

Round Belt Idler Pulleys

Spin freely on built-in bearings to reduce wear and vibration on round belts

Flat Belt Drive Pulleys

Flat Belt Drive Pulleys

Pair with a flat belt to transfer motion from a rotating shaft

V-Belt Idler Pulleys

V-Belt Idler Pulleys

Spin freely on built-in bearings to reduce wear and vibration on V-belts

Gear Boxes

Transmit rotary motion without changing speed, or reduce speed while increasing torque

Gear Box Shafts

Gear Box Shafts

Convert output drives from female to male

Gear Box Mounts

Gear Box Mounts

Secure gear boxes that can’t be attached directly to a machine or other surface

Idler Shafts

Support idler sprockets and pulleys in tensioning applications

Measuring and Inspecting

Calipers

Take inside, outside, and depth measurements with more precision than a ruler

Gear Tooth Gauges

Gear Tooth Gauges

Identify your gear's pressure angle, pitch, and module

Fabricating and Machining

Gear Cutters

Mill spur gears with a 14 1/2° pressure angle

Material Handling

Conveyor Belt Drive Sprockets

Conveyor Belt Drive Sprockets

Transmit power to chain belting to keep it running smoothly
