Special Packing for Rod Seals
R = 0.3 or below, R1 = 0.5 or below, R2 = 1
The surface of the rod should be finished by buffing (SPBF) to 0.8 to 1.6 μmRz (0.2 to 0.4 μmRz).
•The roughness is JIS B 2601 : 2001. When regulation length cannot be kept, apply Pt.
How to Determine B dimension
■ When using backup ring. Please determine B dimension according to the table below.
■ When not using backup ring.
To determine B dimension, please refer to the graph in the right

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.
