CDQ2B25-20DCZ Applications
This is the cushioned sibling of the standard CDQ2B25-20DZ: the C body option fits a rubber bumper so the piston does not bottom out hard at either end of the 20 mm stroke. Specify it for fast-cycling stoppers, part ejectors, clamp arms and transfer pushers where impact noise, vibration or fixture damage is a concern. The 25 mm bore delivers solid thrust and the compact through-hole body keeps the installation shallow.
