Description
The YSR-20-25-C absorbs up to 60 J per stroke and 92000 J per hour, protecting drives, stops and workpieces from hard end-position impacts. No adjustment is needed on the YSR in size 20 because the cushioning adapts itself to the load.
Benefits
- Energy absorption up to 60 J per stroke and 92000 J per hour
- Impact speed up to 3 m/s
- Stop force up to 3000 N, residual energy max. 0.32 J
- Return time 0.3 s, return force 10 N
- Mounting with lock nut, size 20
- Housing in galvanised steel, CRC 2
Applications
The YSR is used on linear axes, rotary actuators, grippers and stops where masses should come to rest at the end of stroke without rebound. The YSR-20-25-C is rated for -10 to 80 °C ambient temperature, any mounting position.
