When it comes to protecting powertrain components in industrial equipment, choosing the right oil seal is more than just a detail—it’s a critical decision that directly affects performance, safety, and service life. The TG4 oil seal series, engineered for environments with high rotational speeds and demanding pressure conditions, offers a robust sealing solution for a wide range of mechanical systems. Known for its dual-lip design and reinforced structure, the TG4 series is particularly well-suited for dynamic sealing in gearboxes, pumps, and motor shafts.
But what makes the TG4 series a trusted choice for manufacturers and maintenance professionals?
Let’s explore.
Technical Features and Applications
TG4 oil seals are characterized by a spring-loaded inner lip combined with an auxiliary dust lip. This dual-action profile helps maintain effective fluid retention while preventing external contaminants like dust, moisture, or abrasive particles from penetrating the system. Made from durable elastomers such as NBR or FKM, TG4 seals offer excellent resistance to petroleum-based lubricants and fluctuating temperature cycles.
TG4 seals are widely used in:
1. Industrial machinery such as gear reducers, hydraulic pumps, and processing equipment.
2. Automotive systems including engines, transmissions, and heavy-duty axles.
3. Energy and power equipment such as wind turbines and electric motors.
4. machinery, where dust and vibration are constant challenges.
5. Hydraulic and chemical processing systems, where leakage can compromise
both safety and efficiency.
