50Hydraulic PTFE rotary seals
High pressure Rotary Seals is one bidirectional rotary seal which can bear both sides of pressure and alternating pressure.
High pressure rotary seals are used in pneumatic and low to medium load rotary or swing applications. The rotary piston seal is a two-piece design consisting of a standard size O-ring that powers the wear-resistant PTFE cover.
The rotary piston seal provides long-term wear and low friction without stick slip. The PTFE outer diameter has special interference with the O-ring design to eliminate the rotation between the O-ring and the seal. The inner diameter of polytetrafluoroethylene (PTFE) is designed with special grooves to provide lubrication and produce labyrinth effect to reduce leakage.

Advantages: 1. Simple groove, small dimension. 2. Good friction resistance, no creeping. 3. Good abrasion resistance, crumpling resistance, high temperature resistance. 4. With good chemical corrosion resistance, also can choose different material o-rings, it almost can work with all medium. 5. The maximum diameter of product can reach 2000mm. |

High-pressure Rotary shaft seals are one bidirectional rotary seal which can bear both sides of pressure and alternating pressure. It is made with slip ring and o-ring/square ring.
Rotary shaft seals with PTFE ring have been specially developed for use in harsh conditions. They are used when shaft seals with classic elastomer lips reach their performance limits.
PDR rotary shaft seal extends the boundaries of elastomeric radial shaft seals, utilizing advanced materials and design techniques to provide optimal sealing performance for each application. The result is a superior sealing solution that retains a compact sealed casing.
Swivel joint ball plug is working together with hammer union seals, to seal the balls of high pressure elbows and grease.
JST's metal end cap seal is elastomer bonded onto 2 steel caps. This provides high level of extrusion resistance.
The FHB seal is made of a helical wound spring and a polymer jacket, which is mainly used as a Flange internal face seal.
DKBI wipers are installed in the sealing configurations of hydraulic cylinders to prevent contaminants such as dirt, dust and moisture from entering the cylinder as they retract back into the system.
Phenolic wear rings are designed with tubing made from fine weave cotton fabric wound on molds and imbued with phenolic resin. It has high mechanical properties, good oil resistance, low water absorption and high wear resistance.
