A TC Oil Seal, also known as a lip seal or rotary shaft seal, is a critical component in mechanical systems designed to prevent the leakage of lubricants and the ingress of contaminants. T stands for double lip and C stands for. rubber coated. The main lip of the double-lip skeleton oil seal is used to prevent oil, and the secondary lip. is used to prevent dust.TC stands for “Triple Contact,” signifying the unique ability of this seal to engage with the shaft surface in three distinct points. This feature significantly enhances its effectiveness in retaining oil while simultaneously preventing dirt, dust, moisture, and other aggressive elements from entering sensitive machinery.

The TC Oil Seal comes with a multi-part construction that includes three essential elements:

1. Seal Body: Typically made from elastomeric materials like Nitrile Rubber (NBR), Viton, or Silicone, the seal body provides the necessary flexibility and resilience to withstand a wide range of temperatures and pressures. The choice of material depends on the specific application requirements, including oil compatibility and environmental conditions.

2. Spring Element: Many TC Oil Seals incorporate a stainless steel or carbon spring, which exerts a constant force against the sealing lip. This ensures that the lip maintains contact with the shaft, achieving a reliable seal even under varying operational pressures and speeds. The spring also compensates for wear and tear over time, extending the overall lifespan of the seal.

3. Sealing Lips: The most critical part of the TC Oil Seal, the sealing lips are specially designed to create a barrier against leakage. The lip geometry is optimized for low friction and high conformity, ensuring a tight seal with minimal wear. The inner (or dynamic) lip is specifically tailored to retain oil, while the outer (or static) lip serves to prevent the ingress of contaminants.
