Riken ULF Series Pancake Jacks
Single-acting, load-return 2000 bar (200MPa) pancake jacks.
- The piston is allowed to be inclined at a maximum angle of 4°
CAUTION: The ULF Series Cylinders have no piston stop ring. If the piston advances 10mm or more (when the stroke-end indicating groove appears), it will be ejected - causing oil leakage which may result in the cylinder needing repair.
