- Paper mill roller compression systems
Installation note:
Requires periodic lubrication (ISO VG32 hydraulic oil recommended).
For vertical installations, use rod-end support brackets to prevent
piston rod deflection. Magnetic switch grooves (5mm width) pre-machined
on cylinder body for sensor mounting.
