Durapac RFJ-50 Single Acting Low Height Flat Cylinder
The RFJ-50 is a spring return, compact flat cylinder designed 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 pancake cylinders (jacks) 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.
- For applications requiring extra closed height flexibility the RFJ stack plate kits from 5-30 ton capacity are the perfect tool.
