Precision TG Type Oil Seals – Advanced Corrugated OD Sealing Solutions

TG Type Oil Seals (Ribbed Outer Diameter Seals) are specialized radial shaft seals engineered for high-integrity static sealing in demanding industrial environments. Unlike smooth-bore alternatives, the TG profile features a corrugated elastomer outer shell which provides superior grip and compensation for thermal expansion within the housing bore. This design is particularly critical for light-alloy housings or applications subject to high-frequency vibration, where maintaining a leak-free static interface is as vital as the dynamic seal on the shaft.

Xiamen Best Seal manufactures TG Oil Seals using high-modulus NBR, FKM (Viton), and specialized polymers to support extreme pressure and temperature variables. Our TG series incorporates ISO 9001:2015 manufacturing protocols and PPAP Level 3 documentation, ensuring every seal meets the micron-level tolerances required for precision power transmission and hydraulic systems. Advanced CCD automated optical sorting ensures that the corrugated profile and sealing lip are perfectly molded for zero-defect performance.

✵ Static & Dynamic Integrity ✶

The Advantage of Ribbed Outer Diameter Engineering

The TG's unique Corrugated OD isn't just a design choice; it's a mechanical solution for high-tolerance bores. The "valleys" between the ribs act as stress-relief points, allowing for easier press-fit installation while maintaining a higher radial force against the housing wall.

◌ Superior Static Sealing: The ribbed profile creates multiple sealing points, effectively blocking leakage paths even in roughly machined or worn housing bores.
◌ Reduced Insertion Force: Corrugation reduces the contact area during installation, preventing seal tilting or damage during assembly.
◌ Thermal Expansion Compensation: Ideal for aluminum or light-alloy gearboxes where expansion rates differ between the seal and housing.
◌ Primary Dynamic Lip: Features a garter-spring energized lip for precise contact pressure and optimized film thickness on the shaft.

Expert Technical Support Q&A

Q: Why is the corrugated OD preferred for aluminum housings?
Aluminum has a higher thermal expansion coefficient than steel. The ribbed OD (corrugation) of the TG seal allows it to maintain consistent sealing pressure against the bore even as the housing expands and contracts during thermal cycles.

Q: Does the TG seal require specialized installation equipment?
No, but the ribbed design actually makes manual and hydraulic installation easier by reducing the initial insertion force compared to a smooth-bore rubber seal.
