Product Introduction

The JB-3 polyurethane seal is a rod seal with asymmetric lips and double lip in hydraulic cylinders. The Mainly used as a piston rod seal for heavy-duty construction machinery and industrial hydraulic applications.


Characteristics


Excellent wear resistance

High resistance against extrusion

Unaffected by transient loads and high pressure

Small compression deformation

Adapt to the harsh working conditions

Prevent entry of outside air

Simple installation

Application Suggestion

JB-3 rod seal is mainly used for the sealing of piston rods and plungers in heavy-duty machinery. It is mounted on its outer diameter by positioning. The rear dynamic sealing lip improves leakage characteristics while preventing contaminants from entering the atmosphere. Compared to JB-2, JB-3's inner lip is shorter and more flexible, so it can better adapt to working conditions and piston rods bending deformation. Groove and diameter dimensions are in accordance with ISO5597/1 and ISO3320 international standards respectively.
