What is the difference between TC oil seal and TG oil seal?TC oil seal: rubber shell, suitable for conventional working conditions, cost-effective, easy to install.TG oil seal: metal shell, suitable for high-strength, high-precision, high-speed environment, stronger performance but slightly higher cost.
Comparison Items | TC OIL SEAL | TG OIL SEAL |
---|---|---|
Shell material | Rubber covered metal case | Full metal case |
Lip structure | Double lip structure (one main lip + one dust lip) | Double lip structure (one main lip + one dust lip) |
spring | Yes (used to enhance the sealing force of the main lip) | Yes (used to enhance the sealing force of the main lip) |
Pressure resistance | General (applicable to normal pressure conditions) | Stronger (suitable for mild high pressure and high speed) |
Installation Features | Rubber outsourcing has strong adaptability and better sealing | Metal housing is suitable for high-precision assembly and hard shell |
Corrosion resistance | Stronger (rubber surface anti-corrosion) | Weak (pay attention to the shell material, such as stainless steel, etc.) |
price | Relatively cheap | Slightly higher cost |
✅ 2. Application scenarios of TC oil seals
-Automobile gearbox, differential
-Agricultural machinery, power tools, pump equipment
-Working conditions that require both oil sealing and dust prevention
-Equipment with dusty or easily contaminated external environment
✅ 3. Application scenarios of TG oil seals
-Places with relatively clean interiors, such as the inside of motors and compressors
-Parts that only require oil sealing and do not require dust protection
-Applications with limited space or cost sensitivity
