Power Transmission

Spur Gears and Racks

Spur Gears and Racks

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

Worm Gears

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

Miter Gears

Connect shafts at a right angle without changing speed or torque

Bevel Gears

Reduce speed while transmitting motion at a right angle

Helical Gears and Racks

Helical Gears and Racks

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

Ratchet Gears and Pawls

Ratchet Gears and Pawls

Transmit motion in one direction and stop it in the other

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 transfer motion from a rotating shaft

Idler Sprockets

Idler Sprockets

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

Timing Belt Idler Pulleys

Timing Belt Idler Pulleys

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

V-Belt Drive Pulleys

V-Belt Drive Pulleys

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

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

Flat Belt Drive Pulleys

Flat Belt Drive Pulleys

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

Round Belt Idler Pulleys

Round Belt Idler Pulleys

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

V-Belt Idler Pulleys

V-Belt Idler Pulleys

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

Gear Boxes

Adjust motor speed to achieve the right torque for your machine; transmit motion at a 90° angle

Gear Box Mounts

Gear Box Mounts

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

Rotary Shafts

Pair with gears, sprockets, and bearings to transmit rotary motion

Measuring and Inspecting

Gear Tooth Gauges

Gear Tooth Gauges

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

Calipers

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

Fabricating and Machining

Gear Cutters

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

Gear and Bearing Pullers

Gear and Bearing Pullers

Remove gears and bearings from hollow shafts and housings

Material Handling

Conveyor Belt Drive Sprockets

Conveyor Belt Drive Sprockets

Transmit power to chain belting to keep it running smoothly

Lubricating

Oil

Thinner than grease to flow in smaller gaps; dissipates heat and removes dirt and metal shavings
