Power Transmission

Spur Gears

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

Spur Gear Racks

Spur Gear Racks

Match with spur gears to convert rotary motion to linear motion

Internal Spur Gears

Internal Spur Gears

Teeth on the inside mesh with standard spur gears to save space

Helical Gears

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

Spur Gear Stock

Spur Gear Stock

Machine your own gears to an exact face width and shaft diameter

Helical Gear Racks

Helical Gear Racks

Pair with a helical gear to convert rotary motion to linear motion

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

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

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

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 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

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
