LBIK type wiper seal, also known as dust seal, is a specialized external sealing component mounted on the outer side of hydraulic cylinder glands. Its core function is scraping off dust, mud, sand, water and other contaminants attached to the piston rod surface during reciprocating movement. It prevents foreign particles from entering the cylinder interior, protecting the main rod seals and hydraulic system from abrasive wear and premature damage.
Manufactured from high-quality polyurethane material, the LBIK wiper seal boasts excellent abrasion resistance, good flexibility and strong scraping performance. Its sharp lip profile maintains steady contact with the rod surface without scratching the rod. The optimized structure delivers reliable dimensional stability, resisting deformation under harsh outdoor working conditions. It works stably within temperature range from -30℃ to 100℃.
Compatible with mineral hydraulic oil and most common hydraulic media, LBIK dust wiper seals are widely applied in excavators, loaders, forklifts and other heavy construction hydraulic cylinders. It matches standard installation groove sizes for simple assembly and direct replacement. By blocking external pollutants and extending the service life of internal sealing sets, the LBIK wiper seal provides an essential dust-proof sealing solution for heavy-duty hydraulic equipment.
