The 45# steel compression washer is a critical auxiliary fastening component in slurry pump transmission systems. Tailor-made for the Jch-Tiktop 6/4-AH(AHR) slurry pump and various medium-to-heavy-duty slurry pumps equipped with 45# steel shafts, it is precision-manufactured from high-quality 45# carbon structural steel through quenching and tempering processes. Its core function is to collaborate with round nuts, bearings, and other components to achieve axial positioning and locking of impellers and bearing assemblies on the shaft, preventing loosening or displacement under high-load operations. Working in tandem with 45# steel shafts and DAM series bearing assemblies, it reliably withstands axial pressures during transmission, making it suitable for harsh working conditions in industries such as mining, metallurgy, coal, and construction materials. It is an essential foundational spare part ensuring the stable and reliable operation of slurry pump transmission systems.
Crafted from premium 45# carbon structural steel and professionally quenched and tempered, it boasts a tensile strength exceeding 600MPa and a yield strength of ≥355MPa. With excellent hardness and wear resistance, it resists deformation and abrasion under long-term axial pressure, preventing component loosening caused by washer failure. Its service life is significantly longer than that of ordinary carbon steel washers.
Employing CNC lathes and grinders for high-precision processing, the thickness tolerance is controlled within IT7-IT8 grade, and the surface roughness is Ra≤0.8μm. It maintains uniform fit clearance with the pump shaft and round nuts, ensuring tight adhesion and precise axial positioning of components. This minimizes vibration and displacement during operation, safeguarding the coaxiality of the transmission system.
Strictly matching the assembly specifications of 6/4-AH(AHR) slurry pumps and various medium-to-heavy-duty slurry pumps, it perfectly adapts to the installation requirements of 45# steel shafts and DAM series bearing assemblies. When used in conjunction with round nuts, clamping washers, and other spare parts, the locking effect is doubled, significantly enhancing the stability of the entire transmission system.
The 45# steel material endows the washer with excellent toughness and fatigue resistance, featuring an elongation at break of ≥16%. It effectively absorbs impact loads during slurry pump startup, shutdown, and flow fluctuations. Under heavy-duty conditions involving high-concentration, large-particle slurry transportation, it is less prone to cracks or fractures, consistently maintaining reliable locking performance.
Featuring a simple and rational structural design, it is dimensionally optimized for the pump body’s assembly space. Installation and replacement can be completed quickly using standard tools, eliminating the need for complex debugging. This drastically reduces maintenance downtime and operational costs, catering to the high-efficiency requirements of industrial scenarios.
