Rotary Shaft Seal 40x65x10 FPM FKM Viton® TC Double Lip

Fluorocarbon Rotary Seal for Demanding Industrial Applications

FPM FKM Viton® Material and TC Double Lip Protection

Technical Data and Installation Recommendations

Main Description:
The Rotary Shaft Seal 40x65x10 FPM FKM Viton® TC is a high-performance double lip oil seal designed for rotary sealing in aggressive and high-temperature environments. As a precision-engineered rotary shaft seal, it ensures reliable lubricant retention while preventing dust, moisture and external contaminants from entering the system.

The dimensions 40x65x10 indicate a shaft diameter of 40 mm, housing bore of 65 mm and seal width of 10 mm. The TC double lip oil seal construction includes a primary sealing lip supported by a garter spring to maintain consistent radial pressure, along with a secondary dust lip for enhanced environmental protection. Compared to a single lip oil seal (SC type), the TC configuration provides improved sealing security in contaminated or heavy-duty operating conditions.

Manufactured from FPM FKM fluorocarbon elastomer, commonly known under the Viton® brand, this shaft sealing ring offers outstanding resistance to oils and grease, fuels, hydraulic fluids and many aggressive chemicals. FPM material provides superior thermal stability and high durability compared to standard NBR compounds, making it suitable for continuous operation at elevated temperatures in industrial applications.

This rotary oil seal is widely used as an engine seal, gearbox seal or technical seal in pumps, compressors, hydraulic units and automotive drive systems. It operates effectively alongside bearings and rotating assemblies to protect lubrication systems and ensure consistent performance. Correct shaft surface finish, proper housing tolerances and professional installation are essential to maximize sealing efficiency and service life.

For B2B customers in manufacturing, maintenance and distribution, the 40x65x10 FPM TC oil seal represents a reliable solution for hydraulic and automotive seals requiring chemical resistance and long-term operational stability.

FAQ

1. What is the difference between TC and SC oil seals?
A TC double lip oil seal includes an additional dust lip for contamination protection, while an SC single lip oil seal has only one primary sealing lip.

2. Why choose FPM FKM Viton® material?
FPM offers superior resistance to oils, fuels and high temperatures compared to NBR, making it ideal for demanding industrial and automotive environments.

3. How do I select the correct rotary shaft seal size?
The first number matches the shaft diameter, the second the housing bore and the third the seal width. Accurate measurement ensures proper fit and sealing.

4. In which applications is a 40x65x10 FPM seal typically used?
It is commonly applied in gearboxes, engines, hydraulic systems, compressors and heavy machinery.

5. Can this seal handle high temperatures?
Yes. FPM fluorocarbon material is designed for elevated temperature operation within its specified limits.
