Flexible Shaft Couplings

Set Screw Flexible Shaft Couplings

A set screw bites into your shaft to hold the coupling in place

24 products

High-Torque Set Screw Flexible Shaft Couplings

Take on twice as much torque as standard split spiders while a set screw holds hubs in place

15 products

Shock-Absorbing Flexible Shaft Couplings

Flexible spring steel wraps around hub teeth to absorb sharp, momentary load increases

9 products

Metal-Detectable Flexible Shaft Couplings

Spider contains metal to trigger a detector if a piece breaks off, such as in food industry lines

3 products

Flexible Shaft Couplings for Continuous Motion

High-Speed Vibration-Damping Flexible Shaft Couplings

Gear-shaped for high-speed and high-torque applications

8 products

High-Torque Flexible Shaft Couplings

A rugged roller‑chain design for excellent torque and angular misalignment capacity

6 products

Ultra-High-Torque Flexible Shaft Couplings

The rigid steel gear design transmits more torque than other couplings

6 products

Lightweight Flexible Shaft Couplings

Nylon sleeves reduce weight and lower energy consumption

6 products

Other Products

Rigid Shaft Couplings

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

15 products

Shaft Adapters

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

4 products

Shaft Collars

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

51 products

Machinable Shaft Ends

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

4 products

Chain and Belt Torque Limiters

Prevent chain or belt damage from overloading; loads above the set torque trigger a stop

16 products

Bearing Adapter Sleeves

Close gaps between your bearing and shaft for a tight fit

2 products

Pulley and Sprocket Bushings

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