SMC CD85N8-80-A AIR CYLINDER

The SMC C85 pneumatic cylinder takes the ISO 6432 standard series and offers it in double-acting, single-rod version, available from Ø 8 to Ø 25 mm. Elastic cushioning is fitted as standard, with pneumatic cushioning offered as an option depending on the bore.

Characteristics:
The C85 cylinder operates on compressed air and provides a double-acting linear movement, with the rod extending and retracting under pressure in both directions. Operation is carried out without lubrication, which limits routine maintenance operations.

Elastic cushioning is fitted as standard across all bores, while pneumatic cushioning can be selected as an option (C suffix) from Ø 10 mm onwards to absorb the piston’s kinetic energy more gradually at the end of stroke.

Several mounting fixings are offered as options, including the angle bracket, flange, clevis pin and articulation, as well as rod ends such as the clevis or the spherical rod end. A magnetic position sensor can also be fitted on CD85 models (with integrated magnet) for end-of-stroke detection.
