Polyurethane ring

Polyurethane ring, also known as PU ring, is a ring-shaped sealing and wear-resistant (based on actual reports) accessory made of polyurethane elastomer. It has good hardness, elasticity, and special wear resistance (based on actual reports), and is widely used in mechanical, hydraulic, and mining equipment.

Main Features

Strong performance, much more practical than ordinary rubber

Good elasticity, compression resistance, and resistance to deformation

Oil resistance, aging resistance, long service life

Wide range of hardness, both soft and hard can be customized

Suitable for dynamic sealing and wear-resistant (based on actual reports) working conditions

Common uses

Hydraulic cylinder seals (U-rings, O-rings, seals, etc.)

Wear resistant mining machinery and conveying equipment (based on actual reports)

Mechanical buffer pad, coupling buffer ring

Cylinder, valve, pipeline sealing components

Rubber wheels, rubber rollers, mold protection rings

Applicable working conditions

Suitable for environments with medium low pressure, medium temperature, wear and tear, and oil stains; Not suitable for long-term exposure to strong acid-base, high-temperature hot water, and strong organic solvents (based on actual reports).
