Fastening and Joining

Coupling Nuts

Connect and extend threaded rods

Thread Adapters

Thread Adapters

Join threads of a different type, size, and gender

Power Transmission

Shaft Couplings

Shaft Couplings

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

Shaft Coupling Covers

Shaft Coupling Covers

Shield rigid shaft couplings from dirt, water, and lubricants to extend their life

U-Joints

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

Shaft Adapters

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

Shear Couplings

Shear Couplings

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

Machinable Shaft Ends

Machinable Shaft Ends

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

Flexible Shafts

Flexible Shafts

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

Rod Alignment Couplers

Rod Alignment Couplers

Reduce wear on bearings and seals by flexing when the cylinder and load aren't precisely even

Hydraulic Cylinder Mounts

Hydraulic Cylinder Mounts

Restrain cylinders and secure loads to the end of the rod

Lead Screw Nuts

Lead Screw Nuts

Mate with lead screws to move components in a straight line

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

Torque Limiters

Torque Limiters

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

Building and Machinery Hardware

Mechanical Control Cables

Mechanical Control Cables

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