Slide ring: Filled PTFE or PU
O ring: Nit rile Rubber NBR or FKM
* Other material combinations can be customized
according to working conditions.
The JBRS is an important rod sealing solution in hydraulic cylinders. It’s composed of 2 parts,a dynamic bronze filled PTFE slide ring and an energizer O ring for static sealing.
Strong corrosion resistance
Good resistance to extrusion
Stable size, no temperature impact
Excellent cushioning effect on strong impact pressure
High speed operation allowed
Good dynamic and static sealing performance
Simple groove design & installation
No stick-slip tendency
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.
Hydraulic oil (mineral oil base)
* Further specifications on request,we also supply turning products or semi-finished materials.
1. Could you sell only the PTFE slide rings?
Yes,buying single piece of either the slide ring or the rubber ring is accepted.
2. Could you make seals with customized size(s)?
Yes,we can make custom seals according to your cylinder operating conditions.
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;
2) Custom logo packaging,we will need logo authorization from you if this option is necessary.
