POLYPAC – SELEMASTER SM

Description

Rod seal range has been designed to meet the needs of hydraulic equipments operating at high pressures and subjected to severe loading and vibration conditions.

The main sealing element is manufactured in a highly compression set resistant nitrile. The most important quality of this element is the design of the multiple sealing lips for maximum sealing efficiency and end face configuration, which ensures that the selemaster can tolerate vibrations and severe misalignment.

Support ring is made in cotton fabric reinforced nitrile elastomer; the ‘’U’’ shape is energised when pressure is applied.

The last element is the anti-extrusion ring manufactured in POM.

2) Support ring in cotton fabric reinforced nitrile, NBR 80 Shore A
3) Sealing element in nitrile, NBR 80 Shore A

Note

  • For low-temperature application -50_C to +110_C a special material – code N7C0 – Polypac Ref.: /1AX – 2187 is available
  • For a simple change in the field Selemaster SM in a cut version (Polypac Ref.: /1AXLS) is available on request

Advantages

– High sealing efficiency
– Effective sealing during vibration and shock loading
– Extrusion resistance at high pressure

Application Examples

  • Earth-moving machines
  • Excavators
  • Lift platforms

Technical Data
