JIC-1542931C1, Rod Seal, ID 63.5mm

A PU rod seal is a dynamic sealing component made from polyurethane (PU) elastomer, designed to prevent fluid leakage and protect piston rods in hydraulic and pneumatic systems. These seals are widely used due to their superior wear resistance, durability, and ability to handle high-pressure conditions.

Features & Benefits:

✔ Excellent Wear Resistance – Polyurethane outperforms rubber (NBR, HNBR) in abrasive environments, extending seal life.
✔ High Pressure Resistance – Withstands pressures up to 40 MPa (5800 psi) or more, depending on design.
✔ Good Elasticity & Tear Strength – Maintains sealing integrity even under dynamic movement.
✔ Oil & Chemical Resistance – Compatible with hydraulic oils, water-glycol fluids, and some solvents.
✔ Low Friction – Reduces stick-slip effect for smooth rod movement.
✔ Temperature Range – Typically -30°C to +80°C (–22°F to +176°F), with specialty PU grades up to 110°C (230°F).

Replacement Part Description:

The inch piston seal fits European brand construction machinery, such as CASE, CATERPILLAR, JOHN DEERE, etc.

• Can also be used for single-acting applications.
• Good wear resistance.
• Long service life thanks to application-optimized compounds.
• Constantly low dynamic friction throughout the part’s service life.
• Insensitive to extreme pressure peaks.
• Improved lubrication due to pressure medium deposit in the dynamic contact area.
• Extremely high extrusion resistance.
• Simple fabrication of the housing.
• Installation in open housings.
