Quick LINKS
ROD U-RINGS
Rod U-Rings have an inner lip that is smaller than the outer lip and are typically used in single acting applications. Unlike standard rod U-rings design, this shape also has a lip on the inner face, which greatly improves sealing by reducing the thickness of the oil film and preventing contaminants from entering the system. Almost total guarantee that no dirt and/or air enters the system.
The design involves preloading of the seal body, which allows for easy absorption of stem deflections and excellent sealing due to lip compression during installation. During operation, system pressure is added to the radial mechanical contact forces. JIOrings offers a range of 750 standard sizes.
ADVANTAGES
- Superior static and dynamic sealing effect
- Economical sealing solution
- Simple groove design
- Easy assembly into closed grooves
- Almost full guarantee of
- Good resistance to wear
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.

Nota: 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.
