1. Product Advantages
Superior Protection: Made of high-quality polyurethane (PU), the seal effectively blocks dust, particles, and foreign contaminants from entering hydraulic systems, preventing abrasion to reciprocating piston rods and reducing equipment failure risks.
Durable Performance: Features 90±2A Shore hardness for excellent wear resistance and low friction, ensuring long service life even in frequent motion scenarios.
Flexible Adaptability: Operates stably in a wide temperature range (-35℃~+80℃) and is compatible with hydraulic oil, emulsions, and air, fitting diverse working conditions.
Easy & Space-Saving: Compact cross-section design suits space-constrained installations; tool-free assembly saves time and labor costs for maintenance.
2. Working Principle
The J-style structure of the skeletonless seal creates a tight contact with the piston rod’s surface. When the rod reciprocates, the seal’s lip scrapes off external dust and debris in real time, while its elastic PU material maintains a reliable seal—preventing contaminants from penetrating the hydraulic cylinder and safeguarding internal components (e.g., seals, oil) from pollution.
