Description
For longer travel of 125 mm, this 20 mm bore compact cylinder stays considerably shorter than a standard cylinder with the same stroke, so it fits into tight machine frames. The piston rod ends in an M8x1.25 male thread, so rod eyes, couplings and nuts screw straight on.
Advantages
- Piston rod in stainless steel, TPU rod seal, NBR piston seal
- Mounting dimensions to ISO 21287, interchangeable with standardised compact cylinders from other makers
- Magnetic piston as standard, end positions can be sensed contact-free with cylinder switches
- Operates from -20 to 70 °C on clean compressed air filtered to 40 µm
Applications
- Feeding small parts over longer distances
- Moving light slides and pushers
- Opening and closing flaps and doors
Accessories and spare parts
A matching repair kit for the 20 mm bore is available for servicing. The end positions can be sensed through the magnetic piston contact-free with cylinder switches.
