TC Oil Seals

TC oil seals are double-lip radial shaft seals with a metal case and a garter spring, designed to provide superior protection against contaminants while sealing in lubricant. They are widely used across various industries due to their robust and reliable design.
Key Features and Benefits
Dual Sealing Capability: The primary inner lip retains the internal lubricant, while the secondary "dust" lip provides enhanced protection against the ingress of dust, dirt, water spray, and debris from the external environment.
Integrated Metal Case: The metal case provides structural rigidity, making the seal suitable for high-stress applications, and the rubber-covered outer diameter helps secure the seal in the housing, even with thermal expansion.
Spring-Loaded Lip: A garter spring is integrated into the main sealing lip to maintain consistent radial force on the shaft, compensating for minor shaft runout, wear, and material changes over time.
Enhanced 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 rubber covering 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 (e.g., -60°C to +200°C).
EPDM: Primarily used for resistance to water, steam, and ozone in non-oil-based applications.
Applications
TC oil seals are suitable for a wide range of industrial and automotive applications where both lubricant retention and contamination exclusion are necessary:
Automotive Industry: Used in engines (crankshafts, camshafts), transmissions, and axles to prevent oil leakage and protect internal components.
Industrial Machinery: Found in gearboxes, pumps, and compressors to maintain lubricant integrity and prevent contamination.
Agricultural and Construction Equipment: In components of tractors, excavators, and other machinery operating in dirty, dusty environments.
Aerospace and Marine: Employed in various aircraft and ship components where reliable sealing under demanding conditions is paramount.
