Sprag-based freewheel (TFS)
The TFS series comprises sprag-based freewheel clutches without their own bearings, which are designed for an interference fit of the outer ring. They have two vertical fitting grooves at both ends of the outer ring. The external dimensions correspond to those of the 63 series ball bearings.
MOVET TFS Cam Clutch: Precision, Performance and Compact Design for Industrial Applications
The TFS series cam clutches are high-quality, non-bearing type one-way clutches based on roller cam technology, specifically designed for compact, precise drive solutions. They are intended for a press fit of the outer ring and feature two vertical keyways on both ends of the outer ring. Thanks to their design, the external dimensions match those of Series 63 ball bearings, allowing easy integration into existing housings originally designed for ball bearings.
Compact, Non-Bearing Design
TFS cam clutches are bearing-free, meaning they can be installed directly into housings or machine components where the bearing arrangement is provided separately. This offers maximum flexibility in design and enables space-saving, compact drive solutions.
Accurate Fit and Easy Integration
The bore of the TFS cam clutch is manufactured to H7 tolerance, ensuring a precise connection to the shaft. In combination with the press-fit outer ring and the vertical keyways for secure location, the cam clutch can be reliably integrated into a wide variety of machine designs.
Broad Application Range
MOVET TFS cam clutches are available in various sizes and torque capacities – from 1 Nm to 150 Nm. Whether used in packaging machinery, conveyor systems, assembly automation or special-purpose machines, these cam clutches provide consistent, precise performance. Typical applications include:
-
Overrunning clutch – disengages the drive at overspeed
-
Backstop – prevents reverse rotation of shafts
-
Indexing clutch – transmits torque in one direction only
