High Pressure Shaft Seal
Details
High Pressure Shaft Seal is a heavy-duty rotary sealing solution specially engineered for shafts under sustained high hydraulic pressure. Equipped with spring pre-tightened lip structure, it fixes the leakage defect of ordinary standard oil seals failing under pressurized environments, locking lubricant steadily for long-cycle continuous rotary equipment.

Description

DEDE Seal Co., Ltd. is one of the most reliable manufacturers and suppliers of high pressure shaft seal in China. If you're going to buy bulk high pressure shaft seal made in China, welcome to get pricelist from our factory. All customized seals are with high quality and competitive price.

 

Conventional radial oil seals easily lose sealing tightness when internal system pressure rises, causing oil blow-by and premature failure. Our High Pressure Shaft Seal adopts an upgraded spring-loaded sealing lip structure, which delivers persistent radial compression force to keep the lip closely attached to the shaft surface even under elevated pressure. It effectively retains internal lubricating fluid, cuts leakage rate drastically, and stops external dust, water and grit from invading the bearing cavity, extending the service life of core transmission components. Two industrial-grade rubber materials (NBR & FKM) are optional to match general pressure and high-temperature high-pressure harsh working scenarios.

 

Key Features

 

Specialized structural design exclusive for high-pressure rotary shaft working conditions

Built-in stainless steel garter spring, provides constant preload to maintain stable lip-shaft contact

Greatly suppresses oil blowout and medium leakage under system pressure

Dual material selection: NBR for standard pressure, FKM for high temp & chemical resistant high-pressure environments

Stable mechanical performance for non-stop 24-hour continuous industrial operation

Optimized anti-extrusion skeleton structure, prevents lip deformation under pressure surge

 

Typical Applications

 

 

  • Hydraulic power equipment, hydraulic motors and hydraulic drive units
  • Heavy-duty industrial gearboxes, speed reducers under internal pressure
  • High-pressure industrial transfer pumps, chemical metering pumps
  • Large construction machinery: excavators, loaders, road rollers
  • Farm heavy agricultural equipment: tractors, harvesters, irrigation high-pressure pumps
  • All continuous-running rotary machinery with pressurized lubrication chambers

 

FAQ

 

 

Q1: What performance requirements should rotary sealing components meet under high-pressure operating conditions?

A: Sealing elements need strong lip follow-up capability and stable contact preload. They must resist pressure impact, adapt to slight shaft eccentricity and run-out, and keep good wear resistance to prevent medium leakage under long-term pressure load.

Q2: Does the high pressure shaft seal need special installation requirements?

A2: Yes. The shaft edge should be chamfered to prevent lip scratch during assembly. Apply compatible lubricant on sealing lip. Control installation pressing force; excessive force will deform the seal and reduce pressure-resistant performance.

Q3: Can high pressure shaft seal be used for static sealing scenarios?

A3: It is mainly designed for rotary dynamic sealing. While it can bear static pressure, repeated static-dynamic switching will accelerate lip wear. For long-term static sealing, static gaskets are more recommended.
