UPI type Packing for Both Piston and Rod Seals

Brand :

NOK

Caution

Product Description

Main applicable fluid

- General petroleum hydraulic fluid oil.

Feature

- This can be used both for piston and rod seals.

- This packing has large section and can be used for wide range of operations.

- Material, Iron rubber U801 has excellent wear resistance and sealing ability.

Dimension

For the fitting drawing of the piston 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.

For the fitting drawing of the rod seals.
R = 3 or below.
The inner surface of the cylinder tube should be finished by burnishing (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.

How to Determine B dimension
■ When using backup ring. Please determine B dimension according to the table below.

Maximum Service Pressure		14MPa	21MPa	35MPa	35MPa
Material of Backup ring		19YF			80NP
B dimension	For Rod seals	B ≦ ø D + 1.0	B ≦ ø D + 0.5	B ≦ ø D + 0.2	B ≦ ø D + 0.8
B dimension	For Piston seals	B ≦ ø D - 1.0	B ≦ ø D - 0.5	B ≦ ø D - 0.2	B ≦ ø D - 0.8

■ 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.
