Description
If the air supply fails, this cylinder retracts by itself. The return spring inside the ISO 21287 compact body brings the 25 mm piston back to its home position after every 5 mm stroke. An M8x1.25 male thread on the piston rod takes pressure pads or clevises directly.
Advantages
- Spring return, only one air line and one 3/2-way valve required
- Magnetic piston as standard, identical dimensions with and without magnet
- Stainless steel piston rod, TPU end cushions
- Test pressure 15 bar, speed 30 to 500 mm/s
Applications
- Embossing and marking with a short working stroke
- Clamping and holding workpieces that should be released when pressure drops
- Ejecting and pushing off parts with a 5 mm stroke
Accessories and spare parts
A repair kit for compact cylinders with 25 mm bore is available separately. E.MC offers cylinder switches as accessories for end position sensing via the magnetic piston.
