Quick Links
rod U-Rings
Compact rod U-Rings have symmetrical lips and are generally 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. Designed for small bore cylinders, the compact collar design generates a higher preload which is an advantage in lower pressures and long stroke cylinders. JIOrings offers a range of 130 standard sizes.
ADVANTAGES
- High degree of sealing thanks to the secondary lip
- Economical sealing solution
- Simple housing design Low axial housing height
- Almost total guarantee that no dirt and/or air enters the system
- Good sealing performance even at low pressures
APPLICATIONS
Construction machinery, forklift trucks, injection molding machines, agricultural machinery, mobile hydraulics, standard cylinders, loading platforms and telescopic 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.
