Description
The Norgren RM/940/920 is a double-acting tie-rod cylinder with a 4 in (101.6 mm) bore, 920 mm stroke and a theoretical force of 4420 N.
Benefits in use
- Compressed air drives the piston of the RM/940/920 in both directions, so extending and retracting are both powered.
- The RM/940/920 runs on compressed air within a 2 to 10 bar pressure range.
- The adjustable end-position cushioning of the RM/940/920 can be set to load and speed and protects the attached parts.
- On the RM/940/920 the barrel is made of anodised aluminium alloy and the piston rod of martensitic stainless steel.
- Compressed air is supplied to the RM/940/920 through G3/8 ports.
- The RM/940/920 is rated for ambient temperatures from -20 to 80 °C.
Applications
Typical tasks for the RM/940/920 are linear motion and clamping in pneumatic systems, as well as replacing an identical Norgren cylinder from the Martonair RM/900 series.
