Product Information
DURAPAC – Hydraulic Cylinders are engineered to meet ANSI/ASME B30.1 Standards for
Performance and Safety. The RFJ-Series is a single acting, spring return, low height, flat design
cylinder for use in narrow spaces and areas with low overhead clearance. They can be used in
maintenance, machinery levelling, construction and mining applications.
All RFJ Series cylinders feature a hard chrome cylinder bore and piston rod for maximum corrosion-
resistance and bronze overlay piston bearing area to resist side load induced damage. Mounting
holes are standard on all models and a grooved piston rod end improves load grip.
Cylinder Stack Plate Kits are an effective economical solution where an extra increase in closed
height is desirable. They are designed for use with the RFJ Series flat cylinders and incorporate a
magnet to attach to the cylinder. All kits include an RFJ cylinder and carry case.
Special skill, knowledge and training may be required for a specific task and the product may not be
suitable for all jobs. The user must ultimately make the decision regarding suitability of the product
for any given task and assume the responsibility of safety for all in the work area. Contact a Durapac
representative if you are unsure of your cylinder’s suitability for a particular application.
