HBW Cushion Seal – Heavy-Duty Hydraulic Buffer Seal for Cylinder End-of-Stroke Cushioning.
HBW heavy-duty cushion seal for hydraulic cylinder end-of-stroke buffering. Impact-resistant, low-friction, high-cycle durable. PU, –40°C~110°C, ≤45 MPa, ≤3 m/s.
HBW Cushion Seal – A rugged hydraulic buffer seal engineered to absorb impact energy and provide controlled deceleration during cylinder end-of-stroke cushioning. This double-acting cushioning seal features a pressure-energized lip geometry that delivers reliable sealing while metering fluid flow for smooth deceleration. The impact-resistant polyurethane compound withstands repeated shock loads, pressure spikes, and high-cycle operations without compromising seal integrity. The robust cross-section resists extrusion and deformation under extreme cushioning pressures, while the optimized contact profile minimizes friction and heat generation. This heavy-duty buffer seal is ideal for mobile hydraulics, construction equipment, mining machinery, and industrial cylinders requiring reliable end-stroke deceleration. Material: high-modulus impact-resistant polyurethane. Temp: –40°C to +110°C. Pressure: up to 45 MPa. Speed: up to 3 m/s.
