Shaft Couplings

Shaft Couplings

Connect two shafts to transfer rotary motion from one to the other

Shaft Adapters

Increase or reduce your shaft's diameter to fit equipment, or replace damaged shaft ends

U-Joints

Transfer torque between shafts at an angle; handle more torque and misalignment than flexible shafts

Machinable Shaft Ends

Machinable Shaft Ends

Mill custom pulleys, threaded hubs, sprockets, collars, and sensor targets and mount them to shafts

Shear Couplings

Shear Couplings

Sever the connection between shafts when there's too much torque to protect parts from breaking

Flexible Shafts

Flexible Shafts

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

Shaft Collars

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

Torque Limiters

Torque Limiters

Keep torque at or below a set limit to control tension or braking or protect machinery from overload

Brakes

Control how much and how quickly your drive system slows down

Clutches

Start and stop the transmission of power to machinery

Clutch/Brakes

Control when to transmit power with a clutch and when to hold a load in place with a brake

Rod Ends

Use with connecting rods to support loads and control steering, tensioning, or pivoting motion

Rod End Inserts

Rod End Inserts

Attach to rod ends to increase the amount of misalignment they can handle

Rod End Nuts

Attach to rods, pipe, and tubing to make pivot and hinge points

Rod End Seals

Keep dirt out and lubrication in to extend the life of rod ends

Building and Machinery Hardware

Joint Covers

Shield rotating joints to keep lubricants in and contaminants out

Control Cables

Weave around obstructions to operate valves, throttles, and other machinery from a distance
