Example: In punch press feeding systems, the FA 82 SFT is used with a lever arm for cyclic control, and the RIDUVIT® sprag coating extends the service life
– Typical applications: Inclined conveyors, pressing machines, or any system requiring anti-backdriving
– Indexing applications: Suitable for stepwise or ratchet-type movement
Recommended for medium torque loads (≤ 2,500 Nm) and standard shafts up to 85 mm, where compact design and low maintenance are critical requirements.
