**Mechanical Seal IN0180.58BQQVGG: Technical Description and Specifications**

The IN0180.58BQQVGG is a precision-engineered mechanical face seal belonging to the IN59B/IN58B series catalog. This model is designed for reliable rotary shaft sealing in pumps, mixers, and other industrial rotating equipment. Its construction ensures effective containment of process fluids and exclusion of contaminants, contributing to enhanced operational safety and reduced maintenance intervals.

**Key Design Features and Material Composition**

This seal is configured as a cartridge-type unit with a clamping ring (с прижимным кольцом), which simplifies installation and ensures correct alignment. The primary sealing faces utilize silicon carbide (карбид кремния) for both the rotating and stationary components. This material pairing offers exceptional resistance to abrasion, corrosion, and thermal shock, ensuring long-term sealing integrity and stable performance under demanding conditions. The metallic structural components are manufactured from AISI304 stainless steel, providing robust mechanical strength and good corrosion resistance. The secondary elastomeric sealing element is made from NBR (Nitrile Butadiene Rubber), a material chosen for its compatibility with a wide range of oils, water, and fluids within its operational temperature range.

**Precise Dimensional Configuration**

Accurate **розміри торцевого ущільнення** are critical for proper fit and function. The IN0180.58BQQVGG is engineered for a nominal shaft diameter (d1) of 18 mm. The external diameter of the fixed part (d7) measures 33 mm, while the outer diameter of the moving part (d3) is 36 mm. The overall seal length (L3) is 31.5 mm. These precise dimensions ensure compatibility with standard housing geometries and facilitate straightforward replacement procedures. Consulting the comprehensive **каталог торцевих ущільнень** for the IN58B series is recommended to verify exact application suitability and interchangeability.

**Application and Operational Benefits**

The 58B seal grade denotes a specific design profile optimized for balanced performance in general industrial service. The use of silicon carbide faces minimizes wear and friction, leading to lower power consumption and extended service life. The cartridge design with a clamping ring significantly reduces the potential for installation errors, promoting reliable sealing from initial startup. This mechanical seal is suitable for applications involving water, light chemicals, and various process fluids where the materials of construction are compatible.

**Summary**

The Mechanical Seal IN0180.58BQQVGG represents a robust and reliable sealing solution characterized by its durable silicon carbide faces, corrosion-resistant AISI304 metal parts, and practical cartridge design. Its specified dimensions ensure easy integration into equipment designed for this seal series. For engineers and maintenance specialists, this unit offers a dependable component to maintain system integrity, reduce leakage, and support efficient equipment operation.
