Freewheels
Festo freewheels allow a pneumatic rotary actuator or piston rod to rotate freely and with low resistance in one direction while locking against rotation in the opposite direction. The FLSM series (external thread for direct piston rod mounting) and FLSR series (sleeve version) are available in sizes from 6 to 40 mm in both left-hand (L) and right-hand (R) versions. The range covers 28 items for all common mounting geometries.

How to choose Freewheels
What matters when choosing: properties, comparison and typical applications.
Technical features
FLSM and FLSR type overview
| Series | Bore (mm) | Rotation direction |
|---|---|---|
| FLSM | 6, 8, 10, 12, 16, 25, 32, 40 | Left (L) and Right (R) |
| FLSR | 10, 12, 16, 25, 32 | Left (L) and Right (R) |
Typical applications
Typical applications: Rotary actuators requiring torque in one direction only while allowing free return rotation under load, ratchet-principle indexing drives, and rotary drives in packaging machinery where a backstop is required to prevent reverse movement.
