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. This model has a design specially adapted for heavy working conditions and a great performance in static applications.
ADVANTAGES
- Superior sealing capacity in static applications
- Easy installation in closed grooves
- Good performance in eavy working conditions
- Very good static tightness due to its geometry
- Resistant up to 250 bar pressure with a back-up ring
APPLICATION
Construction machinery, forklift trucks and standard cylinders.
WORKING CONDITIONS
NBR90
FLUIDO | Mineral oils (DIN 51524) | HFA & HFB | HFC |
TEMPERATURE | -30 °C to +105 °C | +5 °C to +60 °C | -30 °C to + 60°C |
PRESSURE | ≤150 Bar | ≤150 Bar | ≤150 Bar |
SPEED | ≤0,5 m/sn | ≤0,5 m/sn | ≤0,5 m/sn |
Note:
For special applications requiring high temperatures, U-rings can be manufactured in FPM.
ROUGHNESS SURFACE
| Ra | Rmax |
Dynamic surface | ≤0,4 μm | ≤3,2 μm |
Groove base | ≤1,8 μm | ≤10,0 μm |
Groove flanks | ≤3,0 μm | ≤16,0 μm |
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.
Maximum permissible gap NBR
C/S | Pressure (Bar) | ||
50 | 100 | 160 | |
≤5 | 0.40 | 0.20 | 0.10 |
>5 | 0.45 | 0.25 | 0.15 |
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.
