The mechanical seal IN0120.103L.BVPGG is a high-precision bellows-type sealing device engineered for reliable operation in rotary equipment such as pumps, mixers, and compressors. This model is a key component within the extensive **каталог торцевих ущільнень** for series IN103/IN103A, designed to prevent fluid leakage along the shaft. Its construction is defined by a carefully selected combination of materials and exact **розміри торцевого ущільнення**, ensuring compatibility and durability in demanding service conditions.

This seal is characterized by its robust material configuration. The primary sealing face, the fixed part, is manufactured from ceramic, providing exceptional hardness and wear resistance against abrasive media. The complementary moving ring is crafted from graphite, a self-lubricating material that ensures smooth running and effective sealing with minimal friction. The critical bellows element, which accommodates axial and angular shaft movements, is made from NBR (Nitrile Butadiene Rubber), offering excellent resistance to oils, fuels, and a wide range of industrial fluids. The structural metal components are fabricated from AISI304 stainless steel, guaranteeing corrosion resistance and mechanical integrity in various environments.

Precise dimensional parameters are fundamental to its performance and correct installation. The seal is designed for a nominal shaft diameter (d1) of 12 mm. The external diameter of the fixed part (d7) measures 26 mm, while the outer diameter of the moving part (d3) is 23.5 mm. The overall seal length (L3) is 15 mm. These specific **розміри торцевого ущільнення** are critical for ensuring a proper fit within the seal chamber and achieving the designed sealing interface pressure. The model designation IN0120.103L.BVPGG incorporates the seal grade 103, indicating its specific design lineage and performance characteristics within the product family.

The bellows-type (сильфонное) design eliminates the need for a dynamic O-ring, reducing friction points and enabling reliable performance in applications where shaft fretting or clogging of springs might be a concern. This makes the IN0120.103L.BVPGG particularly suitable for handling fluids containing particles or in situations with slight shaft runout. When selecting a seal from the **каталог торцевих ущільнень**, this model represents an optimal solution for applications requiring a compact, resilient, and chemically resistant seal for a 12 mm shaft. Its material synergy and precise engineering ensure extended service life, reduced maintenance downtime, and effective containment of process media.
