In the world of rotating machinery, sealing performance is a decisive factor for operational stability and service life. The Rotary Shaft TG4 Oil Seal, developed under the DEDE brand, has become a trusted solution across pumps, electric motors, gearboxes, engines, industrial machinery, robotic arms, wind turbines, metallurgy, chemical plants, hydraulic systems, agricultural machinery, as well as automotive and heavy-duty truck applications.
Structure and Material Advantages
The TG4 oil seal is designed with multiple lips, ensuring both dust exclusion and fluid retention. Common material options include:
FKM (Fluoroelastomer): Excellent resistance to heat and oil, ideal for engines and gearboxes;
NBR (Nitrile Rubber): Cost-effective, suitable for general hydraulic and mechanical systems;
In terms of performance, TG4 seals typically operate under pressures of
0.03–0.3 MPa, with reinforced versions handling higher loads. Temperature ranges
vary from -40°C up to +250°C depending on the compound, making them adaptable to
diverse industrial conditions.
Application Benefits
Pumps & Motors: Prevent lubricant leakage and ensure bearing stability.
Gearboxes & Engines: Maintain sealing under high temperature and speed, reducing downtime.
Robotics & Automation: Minimize friction losses during continuous high-speed motion.
Wind Power & Metallurgy: Resist dust, humidity, and heavy loads, extending equipment life.
Automotive & Heavy Trucks: Secure sealing in demanding road conditions, enhancing reliability.
