40Cr CNC Machined Flanged Bearing End Cover

This precision-machined flanged bearing end cover is crafted from premium 40Cr alloy steel and undergoes professional quenching and tempering heat treatment, achieving a hardness range of HB255-285. It features outstanding structural strength, strong impact resistance and good comprehensive mechanical properties, perfectly suited for long-term operation under heavy-load and variable-load working conditions. The part is professionally engineered to perform three core functions in mechanical systems: effective internal sealing, accurate axial positioning of bearings, and all-round protection for internal bearing assemblies and transmission components.

Key Features

High-Strength Heat-Treated Material: Adopting high-quality 40Cr alloy steel with standardized quenching and tempering process, the product boasts remarkable toughness, surface wear resistance and fatigue resistance. It can withstand frequent impact and heavy pressure without deformation or damage, fully adapting to harsh industrial operating environments.

Precision Tolerance Control: Processed by high-precision CNC machining, the internal stepped bores adopt strict H8 precision fit standard. Equipped with evenly arranged fixing mounting holes, it guarantees high coaxiality and flatness after installation, realizing precise bearing positioning, stable assembly and smooth rotation of the overall shaft system.

Fine Craftsmanship & Long Service Life: All edges are fully deburred and properly chamfered to avoid scratching mating parts and enable quick, convenient assembly and disassembly. The integral solid structure improves overall rigidity and sealing performance, effectively preventing dust, impurities and moisture from entering the cavity, as well as avoiding lubricant leakage, greatly extending the service life of bearings and the whole equipment.

Applications

Widely applicable to heavy-duty gearboxes, speed reducers, engineering machinery transmission systems, hydraulic pumps, as well as various automation equipment and general industrial machinery. It is the ideal matching component for occasions that demand high-precision bearing installation, reliable sealing effect and durable positioning performance.
