E.MC ✓ Original product Brand new

Description

One air connection and one 3/2-way valve are all it needs: the compact cylinder from the E.MC SF series extends 20 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

  • 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
  • Magnetic piston as standard, identical dimensions with and without magnet
  • Stainless steel piston rod, TPU end cushions

Applications

  • Stops and separators that spring back to their home position
  • Embossing and marking with a short working stroke
  • Clamping and holding workpieces that should be released when pressure drops

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.
