QUICK LINKS
ROD U-RINGS
Rod U-Rings have a lower inner lip than the outer lip and are generally used in single-acting applications, either hydraulic in the case of PU/TPU or pneumatic in the case of NBR.
Their design presupposes a preloading of the seal body which allows easy absorption of stem deflections and excellent sealing thanks to the compression of the lips during installation. During operation, the system pressure is added to the radial mechanical contact forces. JIOrings offers a range of 400 standard sizes.
ADVANTAGES
- Superior static and dynamic sealing effect
- Economical sealing solution
- Simple grrove design
- Easy assembly into closed grooves
APPLICATIONS
Construction machinery, fork-lift trucks , injection moulding machines, agricultural machinery, loading platforms and standard cylinders.

Note:
The largest sealing gap value occurring on the non-pressurized side of the seal does have a vital importance for the function of the seal and in this respect it is quite important to use the S value lower than the above indicated numbers.
