Description
Structural Design:
MD-L seals are double-acting piston seals and have a nitrile rubber (NBR) sealing ring with thermoplastic polyester elastomer (TPC) anti-extrusion rings on both sides, which incorporate the polyacetal (POM) guide rings.
Elastomer has an good sealing effect in both dynamic and static conditions,back up ring prevent the elastomer be extruded into the sealing gap.
The role of the guide ring is to help the piston in the cylinder guide and absorb the radial force.
Summary of Advantages:
- Well proven design
- Long service life
- Excellent load holding capability
- Superior load bearing capability with special reinforced material for guide ring
- No additional guide ring requirement at low and medium duty applications thanks to compact design
Typically made from polyurethane, alternative materials can be provided upon request to suit your specific needs.
