Why use a
flexible drive shaft?

A flexible drive shaft carries rotary power between components while following a curved or offset route. It can help where alignment is difficult, space is restricted or the driven equipment needs to move.

The correct shaft depends on its torque, speed, rotation direction, length, bends, environment and end connections.

Accommodates alignment differences

Flexible Shafts have no need for the tight tolerances that solid shafts require.

mechanics icon

Provides greater design freedom

Limitless possibilities in positioning motor and driven components.

mechanical icon

Supports efficient power transmission

Flexible Shafts are 85%-95% efficient. Gears, U-Joints Belts and Pulleys give much lower performance due to greater frictional losses.

mechanical icon

Handles substantial offsets

Flexible couplings allow only 5 degrees of offset and U-Joints 30 degrees, but with a 40-50% decline in efficiency. Flexible Shafts permit a full 180 degree off-set while maintaining their high efficiency.

mechanical icon

Compact and lightweight

Flexible Shafts have a 3 to 1 weight advantage over other design solutions while transmitting greater power loads.

Can simplify installation

Flexible Shafts install in minutes without special tools or skills. Solid Shafts, Gears, Pulleys, and Universal Joints require precise alignment and skilled mechanics for their installations.

cost icon

Can reduce component count

Bearings and housings for Solid Shafts and Gears require precise machining operations. Flexible Shafts eliminate the need for such demanding tolerances and their excessive costs.

Straightforward to connect

Need no special installation tools.

frequently asked questions

Flexible drives, also known as flexible drive shafts or flex shafts, are versatile components used in various mechanical systems. Here are some of the most frequently asked questions about them:

What is a flexible drive shaft?
A flexible drive shaft transmits rotary motion between a power source and a driven component while following a curved or offset route.
Yes. The inner core, outer casing and end fittings can be selected or designed around the operating duty, route and connection requirements.
Useful information includes torque, speed, rotation direction, overall length, bend radius, operating environment and details of both end connections.
Yes. Photographs, measurements, drawings, identification marks or an existing sample can help the team assess a replacement.
