Application Data
The proper application of a fluid power cylinder requires tension loading on the rod, mounting attitude, the speed
consideration of the operating pressure, the fluid of stroke, and how the load in motion will be stopped.
medium, the mounting style, the length of stroke, the Information given here provides pressure rating data for
type of piston rod connection to the load, thrust or pneumatic and hydraulic cylinders.

Pressure Ratings
Pressure ratings for Series 3L hydraulic cylinders vary by higher than those indicated, Series 2H heavy duty cylinders
bore size and rod size as shown in the table. For pressures should be used.
