All Results

Power Transmission

Rotary Shafts

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

Idler Shafts

Support idler sprockets and pulleys in tensioning applications

Mounted Bearings

Mounted Bearings

Ball, roller, and sleeve bearings ready to bolt in place

Ball Bearings

Create less friction than other bearings for use at high speeds

Linear Bearings

Linear Bearings

Minimize friction as parts move along a shaft

Flanged Sleeve Bearings

Flanged Sleeve Bearings

A sleeve and thrust bearing in one to support both parallel and perpendicular loads

Sleeve Bearings

Sleeve Bearings

With no moving parts, the plainest type of bearing

Roller Bearings

Roller Bearings

Support higher loads than ball bearings, but run at lower speeds

Thrust Bearings

Thrust Bearings

Support loads parallel to the shaft with plain, ball, or roller bearings

Ball Screw/Splines and Bearings

Ball Screw/Splines and Bearings

Transmit rotary power, move loads along the shaft, or do both at once

Bevel Gears

Reduce speed while transmitting motion at a right angle

Worm Gears

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

Spur Gears

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

Ratchet Gears and Pawls

Ratchet Gears and Pawls

Transmit motion in one direction and stop it in the other

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

Miter Gears

Connect shafts at a right angle without changing speed or torque

Ball Splines and Bearings

Ball Splines and Bearings

Combine ball splines and bearings to create linear and rotary motion systems

Flexible Shaft Couplings

Flexible Shaft Couplings

Connect two shafts that are misaligned to transfer rotary motion from one to the other

Rigid Shaft Couplings

Rigid Shaft Couplings

Join two shafts that are aligned and handle higher torque than flexible shaft couplings

Shaft Collars

Hold and position parts on a shaft, or limit shaft movement

Drive Sprockets

Drive Sprockets

Mount directly onto a shaft to transmit rotary motion and torque

Idler Sprockets

Idler Sprockets

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