The CFKS 90*146*12 Tb Oil Seal is specifically engineered for high-precision industrial applications where structural stability is paramount. As a specialized Tb Type NBR Oil Seal, it features an external metal casing that ensures a secure, high-tension press-fit into the housing. This metal-to-metal contact prevents the seal from shifting or popping out under pressure, making it an ideal pump seal for high-vibration environments. The rigid design of the TB series provides better heat dissipation than rubber-covered alternatives, which is critical for the longevity of high-speed rotating shafts.

 

Utilizing high-grade Nitrile (NBR) rubber, this Tb Oil Seal offers exceptional resistance to mineral oils, hydraulic fluids, and grease. The double-lip construction includes a primary sealing lip reinforced with a garter spring to maintain constant radial pressure on the shaft. This is complemented by a secondary anti-dust lip that acts as a vital shield against grit, moisture, and debris. This dual-protection mechanism significantly extends the service life of the 9014612 assembly, ensuring peak performance for industrial gearboxes and hydraulic systems.

Designed to meet or exceed OEM standards, the CFKS Tb Type NBR Oil Seal is the trusted choice for heavy-duty machinery and agricultural equipment. Its robust construction makes it a versatile pump seal capable of withstanding the rigorous demands of continuous operation. By choosing a CFKS Tb Oil Seal, maintenance professionals can minimize downtime and prevent costly oil leaks. We provide reliable, leak-free sealing solutions that protect your internal bearings and drivetrain components from premature wear in the toughest industrial conditions.

Frequently Asked Questions (FAQ)

Why does my CFKS oil seal fail prematurely? Common causes and prevention tips2025-06-26T15:44:39+08:00

Premature oil seal failure can result from improper installation, poor shaft finish, incorrect material selection, or excessive pressure. To prevent this, ensure the shaft surface is smooth and within tolerance, use correct tools during installation, and choose seals made from materials compatible with your media and temperature.

How to correctly install a CFKS industrial oil seal to avoid leakage2025-06-26T16:04:32+08:00

Always clean the shaft and bore before installation. Use appropriate seal drivers to avoid deformation. Lubricate the lip before fitting to reduce friction during the first rotation. Ensure the seal is seated evenly and not tilted to avoid leaks.

What to do when your CFKS hydraulic seal is leaking under pressure2025-05-20T16:33:14+08:00

Check if the pressure exceeds the seal’s rated limit. Examine for wear, hardening, or improper installation. Replace the seal if damaged, and consider upgrading to a high-pressure CFKS seal variant. Also, verify that the housing and shaft are properly aligned.

How to choose the right CFKS oil seal for extreme operating environments2025-05-20T16:34:39+08:00

For high temperatures, aggressive chemicals, or abrasive environments, choose CFKS seals made of FKM, PTFE, or high-performance elastomers. Consider using seals with protective dust lips or metal casing. Our team can recommend the best fit for your application.
