Technical Specifications

Description &Advantages

 

The NS-28 is a compact assembly designed and developed specifically for one piece pistons. The assembly comprises a wear-resistant polyurethane slip ring which is loaded by an NBR ring. There are split 'L' shaped anti-extrusion bearings made from POM on both sides of the seal. The proportions of the range have been determined to give a satisfactory performance when used with the recommended operating conditions. NS-28 can be manufactured using two different profiles as shown in the below mentioned picture.

  • Long life due to wear resistant Polyurethane slip-rings
  • Easy installation
  • Excellent working at high pressure
