Flexible Shaft Couplings

Spider Couplings

A rubbery center fits between hubs to enable torque transfer and damp vibration

52 products

Precision Beam Couplings

Slits on the one-piece body flex to help transfer full torque and compensate for tiny misalignments

136 products

Precision Spider Couplings

Position shafts on motors, pumps, and other equipment that requires highly controlled movements

14 products

High-Torque Spider Couplings

A thicker split spider helps transmit higher torque than standard split spider couplings

4 products

High-Axial-Misalignment Sleeve Couplings

A gear-shaped sleeve helps withstand high axial misalignment and damp vibration

11 products

High-Torque Chain Couplings

A roller chain locks onto teeth on the hubs to withstand high torque

8 products

Sleeve Couplings

More lightweight than other sleeve couplings to reduce energy consumption

15 products

High-Parallel-and-Angular-Misalignment Precision Double Loop Couplings

Offset hubs compensate for high parallel and angular misalignment

119 products

Torque-Limiting Shear Couplings

When torque is too high, sever the connection between shafts so connected parts don't break

21 products

Precision Bellows Couplings

A thin-walled, corrugated-metal center tube flexes to handle all types of misalignment

10 products

Shock-Absorbing Grid Couplings

Flexible spring steel absorbs sudden load increases from starts, stops, and reversals

7 products

High-Parallel-Misalignment Slotted Disc Couplings

Handle parallel misalignment by allowing shafts to slide independently

7 products

Non-Contact Magnetic Couplings

Magnetic hubs compensate for misalignment by transferring torque without wear or contact

4 products

Other Products

Rigid Shaft Couplings

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

93 products

U-Joints

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

80 products

Shaft Collars

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

506 products

Flexible Shafts

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

41 products

Torque Limiters

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

90 products

Clutch/Brakes

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

5 products

Clutches

Start and stop the transmission of power to machinery

31 products

Mechanical Control Cables

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