Description
If the air supply fails, this cylinder retracts by itself. The return spring inside the ISO 21287 compact body brings the 32 mm piston back to its home position after every 25 mm stroke. Tools and pressure pads screw into the M8x1.25 female thread of the piston rod.
Advantages
- Carbon steel piston rod running in a sintered bronze bearing, PTFE guide ring
- Test pressure 15 bar, speed 30 to 500 mm/s
- Installation and mounting dimensions to ISO 21287, so it swaps with other compact cylinders built to the same standard
- Spring return, only one air line and one 3/2-way valve required
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 25 mm stroke
Accessories and spare parts
A repair kit for compact cylinders with 32 mm bore is available separately. E.MC offers cylinder switches as accessories for end position sensing via the magnetic piston.
