Dimension

                                                                    For the fitting drawing of the rod seals.
R = 0.3 or below, R1 = 0.5 or below 
The inner surface of the cylinder tube should be finished by buring (RLB) or honing (GH) to 0.4 to 3.2 μmRz (0.1 to 0.8 μmRa).
Especially under severe lubricating condition, burnishing is required.
● The roughness is JIS B 2601 : 2001. When regulation length cannot be kept, apply Pt.


                                                                                  For the fitting drawing of the piston seals.
R = 0.3 or below, R1 = 0.5 or below
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.
Maximum Service Pressure15MPa32MPa
Material of Backup ring19YF
B dimensionFor Rod sealsB ≦ ø D + 1.0B ≦ ø D + 0.5
For Piston sealsB ≦ ø D - 1.0B ≦ ø D - 0.5

■ 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 piston or rod.
