Professional O-Ring and Oil Seal Manufacturer, Sealing Solution Supplier Since 2008.
High-Performance GSZ2 Thin Composite Dust Seal
For Seamless Protection in Hydraulic Systems
The GSZ2 thin-type combined dust seal is a high-performance sealing solution integrating a wear-resistant ring (often BROZE PTFE or PU) and a preloading O-ring (NBR or FKM), designed for compact installations where space is limited. Its dual functionality—effectively wiping away external contaminants and residual oil film—ensures reliable protection for hydraulic cylinders, servo systems, and industrial machinery, even under high-speed motion or varying temperature conditions. With excellent sliding properties, deformation compensation, and broad compatibility with hydraulic fluids and media, it guarantees long-lasting, stable operation across diverse applications.

1.Product Advantages
The GSZ2 thin-type combined dust seal boasts a range of outstanding advantages. Firstly, it has excellent sliding performance. The sealing ring made of filled PTFE or polyurethane ensures smooth sliding on the piston rod or plunger with a low friction coefficient, effectively reducing energy loss. Secondly, it eliminates stick-slip and crawling phenomena, ensuring stable operation of equipment, especially in high-frequency reciprocating motions. Moreover, it has strong deformation compensation ability, which can compensate for the deformation of the piston rod or plunger caused by force, temperature changes and other factors, maintaining good sealing and dust-proof effects. In addition, its compact structure saves installation space, making it suitable for equipment with high space requirements. Finally, it has a good dirt-scraping effect, which can effectively scrape off external pollutants, even firmly bonded soil and other impurities, and scrape off the residual oil film attached to the surface of the piston rod from the inside to keep the surface of the piston rod clean.
2.Product Action Principle Diagram
![High-Performance GSZ2 Thin Composite Dust Seal 8]()
The GSZ2 thin-type combined dust seal works through the cooperation of its two main components. The wear-resistant ring with sealing and dust-proof edges is in direct contact with the piston rod or plunger. When the piston rod or plunger moves, the wear-resistant ring can scrape off external contaminants and internal residual oil film due to its structural design. The O-ring, as a preloading element, provides a certain pre-tightening force to the wear-resistant ring, ensuring that the wear-resistant ring is always in close contact with the piston rod or plunger, thus maintaining effective sealing and dust-proof performance. Even if there is deformation of the piston rod or plunger, the O-ring can compensate to a certain extent, ensuring the stability of the dust seal's function.
