The LBH‑type dust wiper seal is a professional external dust‑proof sealing component for hydraulic and pneumatic cylinders, widely deployed in construction machinery, material‑handling equipment, agricultural machines and various industrial reciprocating systems. Produced from high‑grade wear‑resistant polyurethane and elastic compound materials, this LBH dust wiper seal offers superior scraping performance, weather resistance and stable elasticity in tough outdoor working environments.
Its precision‑formed sharp scraping lip firmly contacts the moving rod surface. While the piston rod retracts, it effectively scrapes away dust, sand, mud, metal debris and other external contaminants, keeping foreign particles out of the cylinder interior. It protects main hydraulic seals from abrasive damage and avoids early system failures triggered by dirt intrusion. The outer profile fits standard wiper grooves tightly to prevent shifting or popping‑out during continuous operation.
The LBH‑type dust wiper seal adapts to broad temperature ranges and resists aging from moisture and dust exposure. It works well together with rod seals to form a complete sealing system. Simple installation fits existing standard grooves without secondary processing. Effective dust exclusion prolongs cylinder service life and reduces spare‑part consumption and equipment downtime. Custom sizes and material alternatives can be supplied to fulfill different rod‑diameter demands for global industrial customers.
