IUIS Piston Rod Seal Hydraulic and Cylinder Use
Description:
IUIS is a type of Piston Rod Seal.Rod seals are used in hydraulic cylinders for fluid sealing. They are external to the cylinder head and seal
against the cylinder’s rod, preventing leakage of fluid from within the cylinder to the outside.

How to Determine B dimension :
■ When using backup ring. Please determine B dimension according to the table below.
Maximum Service Pressure | 14MPa | 21MPa | 35MPa |
Material of Backup ring | 19YF | ||
B dimension | B ≦ ø D + 1.0 | B ≦ ø D + 0.5 | B ≦ ø D + 0.2 |
Maximum Service Pressure | 35MPa | 42MPa |
Material of Backup ring | 80NP | |
B dimension | B ≦ ø D + 0.8 | B ≦ ø D + 0.4 |
■ When not using backup ring.
To determine B dimension, please refer to the graph in the right for the maximum extrusion gap (one side)
considering the eccentricity of operating condition of the rod.
