How Does the TCN Pressure‑Resistant Oil Seal Work to Prevent Leakage？

When rotating equipment is in operation, oil leaks aren’t the only concern. High pressure, elevated temperatures, violent pulsations, and shaft eccentricity all pose constant threats—where even the slightest misstep can lead to equipment failure.

NQKSF understands these challenges—that’s why we’ve launched the TCN pressure-resistant oil seal series, engineered specifically for complex pressure environments.

It's more than just an oil seal; it's a stabilizer for your equipment.

Where's TCN's secret weapon?

NQKSF understands these challenges—that’s why we’ve launched the TCN pressure-resistant oil seal series, engineered specifically for complex pressure environments.

Reinforced frame and spring support: Like the ribs of an umbrella, the sealing lip resists deformation or curling—even under extreme pressure.

Outer diameter elastomer coating: Especially effective in light alloy housings—ensuring a tight fit and stable performance, even amid temperature fluctuations.

Material Options:

Nitrile (NBR): Oil-resistant and wear-resistant, cost-effective, and suitable for everyday use.

Fluororubber (FKM): resistant to high-temperature chemicals and suitable for more demanding working conditions.

Spring/frame: Stainless steel or carbon steel, focusing on corrosion resistance and strength.

How much pressure can it handle? And how broad is its range of applications?

TCN pressure-resistant oil seals are rated for pressures up to 0.3 MPa, with certain models capable of exceeding this under specific conditions. With proper cooling and lubrication, they can help overcome performance bottlenecks.

Widely used in:

Water pumps, sewage treatment

Hydraulic motors, gear pumps

Gearboxes, engines

Industrial robots, wind turbine equipment

Construction machinery, agricultural machinery

Chemical equipment, marine machinery

Automotive and heavy-duty truck transmission systems

From urban factories to farmland, wherever there's rotating equipment, you'll find TCN oil seals.
