WG9003321820 Подшипник качения 61820

This 61820 thin-wall deep groove ball bearing is a special supporting bearing for Sinotruk gearboxes. It is precisely forged from high-chromium bearing steel and processed through super-precision grinding and vacuum quenching, with a uniform and compact internal microstructure.
The product features high precision grade, good rotational concentricity, low friction coefficient and smooth rotation, capable of bearing combined radial and bidirectional axial loads.
It is suitable for positioning and supporting gear shafts of gearboxes, resistant to high-speed operation, heavy-load impact and high-temperature oil contamination environments. It has excellent dustproof and sealing performance to effectively block the intrusion of impurities. Fully compliant with original factory standard dimensions, it allows easy replacement and installation, and is applicable to the working conditions of various heavy-duty truck gearboxes.
Selected high-carbon chromium bearing steel as raw material, featuring high strength and high hardness, outstanding wear resistance and fatigue resistance, and resistance to pitting and peeling, ensuring long service life.
Adopting precision superfinishing technology, it operates with low noise and small transmission resistance, effectively improving the transmission efficiency of the gearbox.
With thin-wall and lightweight structure, it has strong load-bearing capacity, fits narrow installation space and delivers excellent compatibility.
It is high temperature resistant, oil pollution resistant, dustproof and impurity-proof, maintaining stable operation even under harsh working conditions.
Compliant with original standard dimensions with good interchangeability, it can be directly replaced and installed, reducing disassembly and commissioning time. It effectively alleviates gearbox abnormal noise and stagnation failure, and saves maintenance costs.v
