DSH Seals’ SPN-type shaft Lancaster letter is a two-way piston rod seal consisting of a PTFE bronze composite or a high-hardness polyurethane rod seal ring and an E-ring.
SPN seals are especially suitable for controlling cylinder servo systems, machine tools, cylinder quick response and construction equipment, and two-way piston rod cylinders. This filler has low frictional resistance, which eliminates stick-slip and ensures high wear resistance. When the service range of stress is used, wide and fast sliding speed.

SPN’s sealing ring has high chemical resistance and corrosion resistance. O-rings and sealing rings of different materials can be used. SPN sealing ring can be applied to almost all media. Since the special shape of the sealing structure has good film properties, it can be returned to the oil.

 

Advantages

  • Suitable for one-piece cylinders.

  • Small size installation.

  • Very small start-up and motion friction, ensuring smooth movement even at low.

  • Speeds, no creeping phenomenon.

  • Abrasion, Anti squeeze.

  • Optional high temperature materials.
