Description
When only a few millimetres of movement are needed, this SF series ISO 21287 cylinder with 20 mm bore and 5 mm stroke saves valuable space. The piston rod ends in an M8x1.25 male thread, so rod eyes, couplings and nuts screw straight on.
Advantages
- Magnetic piston as standard, end positions can be sensed contact-free with cylinder switches
- Piston rod in stainless steel, TPU rod seal, NBR piston seal
- Mounting dimensions to ISO 21287, interchangeable with standardised compact cylinders from other makers
- Barrel, end caps and piston in aluminium alloy keep the weight down to 160 g
Applications
- Ejecting small parts from tools
- Clamping and fixing small parts in assembly fixtures
- Stops and pawls on conveyor lines
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.
