DLSEALS PU seal U shaped UNS/UN Piston Rod Seal 75*90*10

Product description

The UNS/UN Piston Rod Seal has a wide cross-section and is an asymmetrical u-shaped sealing ring with the same height of the inner and outer lips. It is easy to fit into a monolithic structure. Due to the wide cross-section, UNS Piston Rod Seal is generally used in a hydraulic cylinder with low pressure.Having been used very widely in hydraulic cylinders, UNS can be used for piston and rod applications because of having the height of both sealing lips equal.   

Polyurethane (PU) is a special material that offers the resilience of rubber combined with the toughness and durableness. It allows people to substitute rubber, plastic and metal with PU. Polyurethane can reduce factory maintenance and OEM product cost. Polyurethane has better abrasion and tear resistance than rubbers, and offering higher load bearing capacity.  

Advantages

● Low friction resistance, no creeping phenomenon ● The dynamic and static sealing effects are quite good ● no viscous phenomenon ● Good performance when there is lubrication and no lubrication ● The groove structure is simple ● High-pressure resistance and adaptability to working conditions ● Multiple choices of specifications
