FAQ

What does the ‘H’ in the type number RM/920H/75 signify?

The ‘H’ designation in older Norgren cylinder series often indicates the use of high-temperature seals, typically made from Viton (FKM). These seals allow the cylinder to operate reliably in environments with higher ambient or fluid temperatures compared to standard NBR seals.

Is this cylinder magnetically cushioned for position sensing?

This specific model from the RM/900 series does not inherently include a magnetic piston for use with external sensors. The standard configuration relies on mechanical or adjustable pneumatic cushioning. If position sensing is required, you would need a model with a magnetic piston and appropriate sensors.

What is the thread size for the air ports and the piston rod?

For a 2-inch (50.8mm) bore cylinder in this series, the air ports are typically G1/4 (BSPP). The piston rod thread is likely M16x1.5. It is always recommended to verify with a thread gauge before connecting fittings to prevent damage.
