SPGW Piston Seal for Hydraulic Cylinders
SPGW
Quantity:
1. Application and properties
Suitable for long stroke and wide range of pressure conditions, and performs excellently in heavy-duty double-acting piston sealing occasions under high pressure conditions.
Good static sealing performance, can be applied to larger piston clearances, and has good leak control, extrusion resistance, and wear resistance in the seal system of heavy-duty and engineering machinery oil cylinder pistons.
Suitable for integral piston, and the installation groove is small.
Compliant with GB/T 15242.1-94 and GB/T 15242.3-94 standards
The outstanding advantages of this seal are good extrusion resistance, low leakage, and long service life. It is widely used in high-pressure heavy-duty oil cylinders (such as excavator oil cylinders).
2. Standard material
Sealing ring: filled PTFE
O-Ring: NBR / FKM
Back-up ring: POM/PA
3. Working conditions.

4. Related Dimensions
R1=0.2～0.5; R2=0.5～1; C=(0.5～1.0)L; e=0.1～0.5, The specific value is selected according to the size of the section of the seal and the level of the working oil pressure, and the remaining values are listed in the Installation Dimensions table.
5. Marking method
Mark with the dimension of installation groove
For example: SPGW100×85×12
