Product Information of SPN-High Pressure Rod Seal PTFE Bronze, NBR/FKM

Company Advantages
1. No harsh chemicals are used in processing DSH ptfe rod seal . And it is tested in terms of strength, durability, and overall safety before shipping. It can work for a long time in acid, alkali, oil and other media
2. DSH set up a strict, well-coordinated and effective quality-guarantee system, with a view to fixing the quality of ptfe rod seal . It features a linear load curve and excellent deflection range
3. The product has excellent deformation resistance. It does not permanently deform or go out of shape even under prolonged compression pressure. It is suitable for applications requiring higher compressive strength and rigidity
4. The product features weather resistance. It has the ability to resist severe cold, hot, dry and humid environment for a long time. It is resistant to virtually every known chemical and solvent

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.
