TA Oil Seals

TA oil seals are double-lip radial shaft seals that feature an external metal case with an additional internal metal reinforcement case and a garter spring. This design offers maximum strength, enhanced rigidity, and superior protection of the sealing lips and spring, making them highly reliable in demanding environments.
Key Features and Benefits
Enhanced Strength: The double metal casing provides maximum structural rigidity and strength, ensuring a secure fit in the housing bore, even in rugged applications.
Dual Sealing Capability: They feature a primary inner lip to retain lubricants and a secondary outer (dust) lip to prevent the ingress of dust, dirt, water spray, and debris from the external environment.
Spring-Loaded Lip: A garter spring is integrated into the main sealing lip to maintain consistent radial force on the shaft, ensuring an effective seal despite minor shaft runout and wear.
Contamination Control: They offer a high level of protection in harsh, polluted environments compared to single-lip seals.
Durability and Versatility: Available in various materials to withstand a wide range of temperature, pressure, and chemical conditions.
Common Materials
The material of the sealing lips and the casing is selected based on the operating environment's temperature, chemical exposure, and shaft speed:
Nitrile (NBR / Buna-N): The most common and cost-effective material, offering good resistance to petroleum-based oils, greases, and fuels within a temperature range of -30°C to +120°C.
Viton® (FKM): Used for applications requiring resistance to high temperatures (up to +200°C) and aggressive chemicals, acids, and fuels.
Silicone (VMQ): Offers superior flexibility and performance in extreme low and high temperatures.
Metal Case/Spring: Typically made from carbon steel for standard applications, or stainless steel for corrosive environments.
Applications
TA oil seals are suitable for a wide range of industrial and automotive applications where both reliable lubricant retention and superior contamination exclusion are necessary:
Heavy Equipment: Used in mining machinery, construction machinery (excavators, bulldozers), and port loading equipment.
Commercial Vehicles: In drive shafts, steering knuckles, and engine components of trucks and buses.
Agricultural Machinery: Essential for sealing components in tractors and harvesters operating in dirty, dusty field conditions.
Industrial Machinery: Found in motors, gearboxes, and pumps to maintain lubricant integrity and prevent contamination.
