ISO 21287 compact cylinder, single-acting, spring return, 25 mm bore, 25 mm stroke, male rod thread - E.MC
Single-acting compact cylinder to ISO 21287: compressed air extends the piston rod by 25 mm and the spring pulls it back. 25 mm bore, M5x0.8 port, a 3/2-way valve is all it takes to control it.

Description
One air connection and one 3/2-way valve are all it needs: the compact cylinder from the E.MC SF series extends 25 mm under pressure and returns to its retracted home position by spring. The bore is 25 mm. An M8x1.25 male thread on the piston rod takes pressure pads or clevises directly.
Advantages
- Stainless steel piston rod, TPU end cushions
- 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
- Ejecting and pushing off parts with a 25 mm stroke
- Stops and separators that spring back to their home position
- Embossing and marking with a short working 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.
