Quick LINKS
Piston U-Rings
Piston U-Rings have a higher 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. Its asymetrical lips design provides a continuous contact with the bore, even in case of high misalignments and a good response to load peaks and low friction in the low-pressure range. JIOrings offers a range of 330 standard sizes.
ADVANTAGES
- Superior static and dynamic sealing effect
- Economical sealing solution
- Simple groove design
- Easy assembly into closed grooves
- Not affected by structural deformation
- Very good resistance to wear and extrusion
APPLICATIONS
Construction machinery, fork-lift trucks , injection moulding machines, agricultural machinery, loading platforms and standard cylinders.

INSTALLATION
Easily assembled into closed grooves according to the minimum diameter values that are given in the below table. Open grooves or special assembly tools should be used for the values that are outside this table. It is very important that the assembly tools must be of soft material and have no sharp edges. Before installation the wiper must be oiled with system oil.

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.
