U‑Cup Balsele are compact, high-performance rod seals combining a shaped elastomer sealing lip with an integrated, fabric-reinforced base. The radial preload design ensures reliable sealing even at low pressures, while the reinforced support blocks extrusion. They offer excellent wear resistance, compatibility with standard hydraulic oils, and a broad temperature range (≈ –30 °C to +130 °C), making them ideal for demanding industrial and mobile cylinder applications
