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

Flanged Sleeve Bearings

Flanged Sleeve Bearings

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

Linear Bearings

Linear Bearings

Minimize friction as parts move along a shaft

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

Pivot Bearings

Best for applications that require small, precise oscillating motion with limited twisting

Sleeve Splines and Bearings

Sleeve Splines and Bearings

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

Ball Screw/Splines and Bearings

Ball Screw/Splines and Bearings

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

Ball Splines and Bearings

Ball Splines and Bearings

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

Flexible Shafts

Flexible Shafts

Snake around curves and obstructions to transmit rotary motion along any path

Rigid Shaft Couplings

Rigid Shaft Couplings

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

Flexible Shaft Couplings

Flexible Shaft Couplings

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

Gear Box Shafts

Gear Box Shafts

Convert output drives from female to male

Spur Gears

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

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

Miter Gears

Connect shafts at a right angle without changing speed or torque

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

Drive Sprockets

Drive Sprockets

Mount directly onto a shaft to transmit rotary motion and torque

Timing Belt Pulley Stock

Timing Belt Pulley Stock

Machine your own timing belt pulleys to fit an exact width and shaft diameter

Idler Sprockets

Idler Sprockets

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

Pulley and Sprocket Bushings

Pulley and Sprocket Bushings

Mount between a rotating shaft and equipment to secure the shaft and reduce vibration

Shaft Collars

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

Linear Drive Nuts

Linear Drive Nuts

Create a linear positioning system on a rotary shaft without a lead screw
