Details

1. Application and properties

  Suitable for two-way and reciprocating piston seal, especially for fast-response cylinders in control cylinders, servo
cylinders, machine tools and construction machinery.
  It has a low friction coefficient, wear resistance, and a long service life. It can work with or without lubrication and
can be used for non-oil lubrication cylinder seals. The adaptability to working media and working temperature range
can be changed by replacing the material of the O-ring. Can be used in special working conditions such as extremely
high speed, extremely low speed, micro-stroke, etc.
  Suitable for integrated pistons and the installation groove is small, which is conducive to design cylinder size
  Complies with the standards of GB/T 15242.1-94 and GB/T 15242.3-94.
  Good extrusion resistance and can adapt to larger installation clearances.
  Different cross-section products can be selected according to the actual working pressure value. Generally, the
larger the working pressure, the larger the cross-section product should be selected.
  This seal is particularly suitable for frequent and rapid directional changes in hydraulic cylinder applications

2. Standard material

  Sealing ring: filled PTFE
  O-Ring: NBR / FKM
