B thE rfJ-SerIeS is a spriNG rEturN, compact
fLat cyLiNDEr DEsiGNED for usE iN Narrow
spacEs aND arEas with Low ovErhEaD
CYLINDERS 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. For applications requiring extra closed
height flexibility the RFJ stack plate kits from 5-30 ton capacity
are the perfect tool.
