BS polyurethane hydraulic seals – high-performance rod seals with dual-lip design. Reduce leakage, extend cylinder life, and lower maintenance costs. Ideal for heavy machinery hydraulic systems.
BS polyurethane hydraulic seals are engineered specifically for dynamic rod sealing applications. Featuring a second lip on the inside diameter, they provide maximum reliability and extended service life in hydraulic cylinders. The durable TPU material ensures excellent wear resistance even under high-pressure and high-speed conditions.
These seals follow PARKER® BS type and size standards, making them ideal direct replacements. Operating temperature ranges from -30°C to +110°C, with maximum pressure up to 30 MPa and speed up to 1 m/s. Suitable for heavy machinery and industrial equipment where leak-free performance is critical.
For hydraulic cylinders suffering from rod seal leakage, pressure loss, or frequent seal failure, BS polyurethane seals provide a proven upgrade. Their dual-lip design enhances sealing reliability and extends maintenance intervals, reducing downtime and total operating costs in demanding environments.
