Product Detail
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
◆◆ PTFE, nbr / fkm rubber
| Material description | PTFE filled Bronze, PTFE filled carbon fiber and MoS2, PTFE filled Graphite, PTFE filled PI, PTFE filled Ekonol, and so on. |
| Available Color | Black, green, coffee, gold and so on |
| Material Strength | With the same performance as SPNO, this is used in case the service range of pressure is wide and sliding speed is high. The packing has low frictional resistance, eliminating stick slip and assuring high wear resistance. |
