PU Polyurethane Round Gasket Pad – 50–200mm Dia, 40mm Thick

PU Polyurethane Round Sheet – Oil Resistant Shock Absorbing Gasket Pad (50–200mm Diameter, 40mm Thick)

Discover our premium PU Polyurethane Round Sheet designed for industrial sealing, vibration damping, and shock absorption. Available in diameters from 50 mm to 200 mm (2"–7-7/8"), with a fixed 12 mm (0.47") inner hole and 40 mm (1.57") thickness. This polyurethane round gasket pad combines high resilience, wear resistance, and oil protection to deliver outstanding performance in heavy-duty applications.

Key Features & Benefits

High-Resilience Polyurethane Material
Made of Shore 75A hardness polyurethane (PU), this round sheet exhibits exceptional mechanical strength, high flexibility, and excellent oxidation stability. Its superior elastic recovery ensures long service life even under continuous compression.

Oil-Resistant and Wear-Resistant Performance
The oil-resistant polyurethane disc resists petroleum, solvents, and water, making it ideal for hydraulic systems, automotive equipment, and petroleum industry machinery. By preventing oil degradation, it maintains consistent damping properties in industrial PU damping pads.

Consistent Dimension Precision
Each PU round sheet is CNC-machined to exact tolerances. Outer diameters from 50 mm (2") to 200 mm (7-7/8"), inner diameter fixed at 12 mm (0.47"), and thickness 40 mm (1.57") ensure a perfect fit. You get reliable performance without worrying about size inconsistencies.

Shock Absorption and Vibration Damping
Engineered as a shock absorbing gasket pad, this product dampens vibration in heavy stamping equipment, large presses, mining machinery, and heavy construction tools. It functions as a heavy-duty sealing gasket that reduces noise, prevents equipment fatigue, and extends machine lifespan.

Industrial Applications

• Hydraulic Press Shock Pads: Ideal for cushioning metal stamping dies and punch molds, ensuring smooth operation and protecting tooling from impact damage.

• Automotive & Heavy-Machinery Sealing: Use as PU sealing rings in engine mounts, transmission parts, and suspension systems to reduce vibration and noise.

• Petroleum & Mining Equipment: Provides oil-resistant cushioning for drilling rigs, compressors, and heavy-load conveyors to endure harsh fluid exposure.

• Construction & Manufacturing: Functions as a vibration‐damping pad for large presses, stamping machines, and heavy machinery to minimize wear and tear.
