Rod-piston seal 57,15x66,68x9,52 UPN PU

Rod-piston seal UPN PU 57.15x66.68x9.52 is used in hydraulic systems, combining piston and rod sealing functions.
The UPN profile is an evolution of the UP seal, merging the elasticity of rubber with the wear resistance of polyurethane.

Material:

• Polyurethane SEALPUR 93 – hardness 93°ShA

• NBR (nitrile rubber) – hardness 70°ShA

Working principle:

• The UPN profile adheres closely to the cylinder or rod surface, preventing leakage.

• An energizing O-Ring improves sealing performance at low pressures.

• The design provides resistance to pressure shocks, low friction, and extended service life.

Technical parameters:

• Pressure: ≤ 400 bar

• Speed: ≤ 0.5 m/s

• Temperature range: –40°C ÷ +100°C

• Fluids: mineral oil-based hydraulic oils

Dimensions:

• Inside diameter (d): 57.15 mm

• Outside diameter (D): 66.68 mm

• Height (H): 9.52 mm

• Inch size: 2.25x2.625x0.375
