Description
For 25 mm of travel, the standard cylinder DSNU-20-25-P-A with a Ø 20 mm piston produces a theoretical force of 188.5 N at 6 bar. The DSNU-20-25-P-A is rated for 1 to 10 bar operating pressure and -20 to 80 °C ambient temperature.
Key benefits
- Theoretical force at 6 bar: 188.5 N advance, 158.3 N return
- Elastic end-position cushioning P at both ends, up to 0.20 J
- End positions can be sensed with proximity switches
- Dimensions to ISO 6432 and CETOP RP 52 P
- Stainless cylinder barrel and piston rod, CRC 2
- Port G1/8, rod thread M8
Typical applications
The slim round cylinder fits fixtures, test stations and handling modules where a Ø 20 mm piston and 25 mm stroke are sufficient. The DSNU-20-25-P-A runs on compressed air to ISO 8573-1:2010 [7:4:4], and it can be mounted in any position.
