About Stieber Freewheels Clutch

Stieber Freewheels Clutch

The Freewheels are directional couplings, which means that the driving member rotates the driven member in one direction, while automatically disengaging itself from the driven part when the direction of rotation is reversed. The two operating states are Transmission of torque and Idling (Overrunning).

Type CSK is a sprag type freewheel integrated into a 62 series ball bearing (except sizes 8 and 40). It is bearing supported, delivered grease lubricated and protected against dust of more than 0.3mm. The use of additional "Nilos" type seals is recommended especially when the working temperature exceeds 50 degree C. Oil bath lubrication is also possible.

All the CSK versions are equipped with "Form chromed" sprags. The process increases several times the overrunning life time.

Torque transmission is ensured by a press fit assembly into a rigid outer housing with N6 tolerance, and onto a shaft with n6 tolerance. The initial bearing radial clearance is set at C5, and is reduced if using the press fit as specified.

Reliable Performance and Design

The FS 25 clutch leverages advanced freewheel technology and a single-row structure for effective motion control. Designed to endure high rotational speeds and heavy loads, it is built from quality chrome steel with a steel retainer and anti-corrosive treatment, ensuring longevity and consistent operation.

Versatile Industrial Applications

Stieber Freewheels FS 25 serves essential roles in machinery requiring backstop, indexing, and overrunning functions. Its high-load capacity and broad temperature tolerance make it suitable for manufacturing, automation, and conveyance systems, providing reliable torque handling and motion precision.

FAQs of Stieber Freewheels Clutch:

Q: How does the FS 25 Freewheels Clutch enhance machinery performance?

A: The FS 25 clutch provides precise torque transmission and prevents reverse rotation, ensuring smooth and reliable operation in applications such as backstop, indexing, and overrunning.

Q: What benefits does the anti-corrosive finish offer in industrial settings?

A: The anti-corrosive finish protects the clutch from environmental wear and moisture, significantly extending its lifespan and maintaining consistent functionality in harsh conditions.

Q: Where can the Stieber Freewheels FS 25 clutch be installed?

A: This clutch is shaft-mounted and can be integrated into various industrial machinery, including conveyors, automation systems, and equipment needing rotational motion control.

Q: When should I use a freewheel clutch like the FS 25?

A: A freewheel clutch is ideal when machinery requires prevention of reverse rotation, safe overrunning operations, or accurate indexing, particularly in manufacturing or material handling setups.

Q: What is the process for maintaining the FS 25 clutch?

A: Regular inspection for wear, checking lubrication (grease type), and ensuring seals and casing integrity form the standard maintenance routine for optimal clutch performance.

Q: What is the application advantage of the metal sealed design?

A: Metal seals safeguard internal components from contaminants and mechanical wear, improving reliability and reducing maintenance frequency, especially in high-demand environments.
