Sealing Excellence, Securing Industry

CFKS NBR TA Oil Seal 120*150*15 Anti-dust TA Rotary Shaft Seal TA Lip Seal

The CFKS TA Rotary Shaft Seal is a premium, double-lip axial seal engineered to provide superior fluid retention and maximum protection against heavy airborne contaminants. Featuring a precision-molded elastomer body and an auxiliary dust lip, it ensures optimal sealing integrity even under intense centrifugal force, making it the ideal choice for demanding industrial drivetrains.

  • Dual-Lip Protection: Primary sealing lip retains lubricants while the reinforced secondary lip blocks external dust and moisture.

  • Optimized Axial Alignment: Engineered to maintain constant contact pressure against the housing, reducing shaft wear.

  • High-Durability Elastomers: Available in premium NBR and FKM compounds to withstand aggressive media and extreme thermal loads.

Product Name: CFKS TA Anti-Dust Oil Seal Specification: 120*150*15 
Material: Premium NBR / FKM / PU Feature: High-Pressure & Abrasion Resistance
Work Temperature: -20℃ to 220℃ Hardness: 70 – 90 Shore A
Type: Double Lip with Garter Spring Usage: Electric motors, gearboxes, pumps, construction machinery, agricultural axles, machine tool spindles.

The CFKS TA oil seal operates on a specialized axial-contact mechanism designed to combat high-contamination environments. Unlike standard single-lip seals, the TA design utilizes a primary sealing lip energized by a garter spring alongside an integrated secondary dust lip. As the shaft rotates, the hydrodynamic action of the primary lip creates a micro-level lubricant film that prevents dry running, while the auxiliary lip leverages centrifugal force to deflect external debris away from the sealing interface. This dual-action geometry drastically minimizes friction and prevents abrasive particles from compromising the bearing chamber.

Component longevity depends entirely on chemical compatibility, which is why CFKS offers the TA profile in both NBR and FKM. NBR provides excellent resistance to petroleum-based oils, hydraulic fluids, and mechanical wear, making it a cost-effective workhorse for standard industrial applications. For operating environments characterized by elevated temperatures or aggressive chemical exposure, our FKM compounds deliver superior thermal stability and aging resistance, preventing the elastomer from hardening and cracking over extended service cycles.

Engineered for seamless integration, the steel-cased OD of the TA seal ensures a tight, static fit within the housing bore, eliminating the risk of OD bypass. During installation, the metal cage provides rigid structural support, allowing for uniform press-fitting without risk of shell distortion. The low-friction coefficient of the optimized elastomer profile ensures a drastically reduced break-in period, significantly lowering localized heat buildup. This translates to an extended maintenance-free lifecycle and prevents the groove-scoring common on shafts paired with lower-grade alternatives.

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.
