WDH TGA oil seal is a specialized textile-rubber oil seal designed for radial sealing applications such as industrial gearboxes, pumps, or heavy machinery.
ABOUT TGA TYPE OIL SEAL
• A textile-rubber reinforced backing, offering flexibility and added structural integrity .
• A rubber sealing lip, supported by a garter spring to maintain contact and compensate for wear over time .
• Axial (A) and radial (R) lubrication grooves, which facilitate lubricant distribution and help extend service life in demanding conditions .
The construction provides enhanced reliability by preventing leaks while accommodating lubrication needs.
Key Features & Benefits
| Feature | Description |
| Textile-Rubber Back | Flexible yet robust, it adapts to imperfect housings and absorbs vibrations. |
| Multiple Sealing Lips | Includes cleaner and auxiliary lips—with a primary sealing lip—for superior redundancy. |
| Threaded Outer Surface | Many TGA seals feature a threaded outer surface for better static sealing and ease of installation compared to smooth TC-type seals . |
| Grooved Design | Dual lubrication grooves (axial + radial) help distribute lubricant and reduce friction . |
| Garter Spring Embedded | Ensures consistent lip pressure and prevents spring loss during assembly . |
TC-type seals: Common design with a smooth outer surface and double lips; widely used but lacks threaded outer surface. TGA enhances this with a threaded outer ring for better sealing and installation retention .
TG (or TG Series): Similar to TGA, but may omit specific groove or backing features. TG variants typically also incorporate three-lip designs and threading for improved performance .
Industrial Textile Rubber Seals (by FP Paris): TGA models from suppliers like FP Paris offer similar construction (textile-rubber backing, grooves, garter spring) and are optimized for heavy-duty sealing environments .
Summary
A TGA oil seal is a robust and advanced sealing solution tailored for industrial radial applications:
Combines textile-rubber reinforcement, multi-lip sealing, and a garter spring for durability.
The threaded outer surface secures the seal and enhances static sealing.
Designed with lubrication grooves to optimize performance and longevity.
