Description
294.5 N advancing force at 6 bar, 350 mm stroke and a piston Ø of 25 mm: these are the key values of the standards-based cylinder DSNU-25-350-P-A. The end positions can be sensed with proximity switches.
Benefits
- Theoretical force at 6 bar: 294.5 N advance, 247.4 N return
- Piston Ø 25 mm and stroke 350 mm, defined by the order code DSNU-25-350-P-A
- Elastic cushioning rings at both ends (P), permissible impact energy 0.30 J
- Cylinder barrel and piston rod in high-alloy stainless steel
- Conforms to CETOP RP 52 P, ISO 6432, standard mounting accessories fit
- Prepared for proximity switches to sense the end positions (code A in the type)
Applications
In fixtures, test stations and special machines the DSNU-25-350-P-A moves workpieces and flaps over 350 mm. The DSNU-25-350-P-A is mounted with DSNU series mounting accessories. For load coupling the piston rod carries the thread M10x1.25, matching accessories for piston Ø 25 mm. For replacement please compare the type DSNU-25-350-P-A with the installed cylinder.
