Application Suggestion

JBRS step seal is used in hydraulic reciprocating system. In high, medium, low pressure and heavy load, the sealing situation under high frequency conditions is very good. Suitable for a wide range of strokes and a wide range of fluids and high temperature applications, as well as a large piston rod clearance. This seal is also suitable for a wide range of strokes and a wide range of fluids and high temperature applications, for larger piston rod clearances. For example, bulldozers, excavators, forging presses, ceramic presses, rolling mills, servo valves and machine tools.

3. What are your commonly used rubber seal materials?

NBR is the most frequently used material of o ring. If the operating temperature is high and harsh,FKM o ring is recommended.

4. How do you pack the items?

Generally,there are 2 ways to pack the seals.

1) Proper packaging with No Marks;
