Rotary Shaft TG4 Oil Seal Global Applications and Reliable Solutions

The TG4 design is based on a multi‑lip structure. One lip retains the
lubricant inside the housing, while the other prevents external contaminants
from entering. This dual function makes it suitable for a wide range of
rotating equipment.

Common material options include:

NBR (Nitrile Rubber): A cost‑effective choice for general hydraulic and
mechanical systems.

FKM (Fluoroelastomer): Excellent resistance to heat and oil, widely used in
engines and gearboxes.

In terms of performance, TG4 seals typically handle pressures between 0.03
and 0.3 MPa. Reinforced versions can withstand higher loads. Depending on
the compound, the temperature range extends from –40°C up to +250°C,
covering the demands of automotive, wind power, metallurgy, chemical, and
heavy machinery industries.

Where the TG4 Seal Makes a Difference

Pumps and Motors: Prevents lubricant leakage and extends bearing life.

Gearboxes and Engines: Maintains sealing under high temperature and speed,
reducing downtime.

Industrial Robots and Robotic Arms: Minimizes friction losses, ensuring
precise and repeatable motion.

Wind Turbines and Metallurgical Equipment: Protects against dust, humidity,
and heavy loads, extending service intervals.

Automotive and Heavy Trucks: Keeps drivetrains sealed even under demanding
road conditions.

These examples show that the TG4 oil seal is not tied to a single sector but
is instead a cross‑industry component that supports multiple supply chains.
