A flexible drive shaft assembly transmits rotary motion much like a solid shaft, but it can be routed over, under, and around obstacles that would make using a solid shaft impractical.  A “Flexible Drive Shaft Assembly” consists of a rotating shaft (sometimes called a core) with end fittings for attachment to the driving and driven mating parts.  A protective outer casing is used when necessary.  This casing has its own fittings, called ferrules, which keep it stationary during use.   A flexible drive shaft assembly is a highly effective means of transmitting rotary motion and is more efficient than Universal Joints, Gears, Sprockets and Chains, or Belts and Pulleys.  It is typically lower in cost than these other devices and offers the added benefit of compensating for misalignments in a system that can greatly reduce cost and assembly time.

Flexible shaft can be employed as an alternative to other forms of rotary power transmission;

Design freedom:

Design your system and place your driving and driven elements in the preferred position.

Design simplicity:

No need to spend precious time ensuring tight drive system tolerances. Flexible shafts take up large misalignments by design.

Moving parts:

Ideal for hand tools or situations which involve constantly changing positions.

Dampens vibration:

Tolerates vibration


Minimum moving parts ensures reliability through simplicity.


Designed to deal with the most complex design requirements.


Supplied as a self-contained drive, the system is fully contained. (MasterFlex)

Simple installation:

Flexible to allow installation in the smallest of spaces.
