Warning

 

A deceleration circuit or shock absorber may be required. 

When a driven object is operated at high speed or the load is heavy, the cushioning of 

the cylinder will not be sufficient to absorb the shock. Install a deceleration circuit to 

reduce the speed before cushioning, or install an external shock absorber to relieve the 

shock. In this case, the rigidity of the machinery should also be examined.
