Back up ring 105x120x3 BRT

The support ring 105x120x3 BRT is an indispensable component in the construction of hydraulic cylinders, especially those intended to operate under high load.
It acts as a stable support for the U-type sealing ring, thereby increasing the efficiency of the entire sealing system.
The ring is made of PTFE composite with an addition of 40% bronze, which ensures its appropriate strength and wear resistance.

The technical dimensional data of the support ring is as follows:
- Inner diameter (d): 105 mm
- Outer diameter (D): 120 mm
- Height / thickness (H): 3 mm

The size in inches for the d × D × H format is: 4.13" × 4.72" × 0.12
