The market recognition of Guanshuo's Single Keyway Motor Shaft stems from our meticulous attention to every manufacturing detail.
1. High-Precision Keyway Machining: Keyway depth tolerance is strictly controlled within ±0.1mm, and keyway symmetry reaches ≤0.02~0.03mm, ensuring precise meshing with mating components and significantly reducing transmission errors.
2. Superior Surface Finishing: The shaft body undergoes precision grinding, achieving a surface roughness of Ra ≤ 0.8μm, effectively reducing frictional resistance and enhancing transmission efficiency. The keyway side roughness is controlled within Ra ≤ 1.6~3.2μm, balancing fit precision with enhanced wear resistance.
3. High-Strength Materials & Heat Treatment: Manufactured from high-strength alloy steel or high-quality carbon steel, combined with quenching and tempering processes, the product offers excellent torsional strength and fatigue resistance. It maintains stable operation even under frequent start-stop and forward/reverse rotation conditions, resisting deformation or fracture.
Every product leaving our facility undergoes rigorous quality inspection to ensure compliance with stringent industrial standards. Leveraging a comprehensive inspection system including hardness testers, two-dimensional projectors, surface finish gauges, and gear testing centers, we perform thorough quality checks. Key technical parameters are as follows:
| Inspection Item | Accuracy Standard |
|---|---|
| Keyway Depth Tolerance | ±0.1mm |
| Keyway Symmetry | ≤0.02~0.03mm |
| Shaft Body Surface Roughness | Ra ≤ 0.8μm |
| Keyway Side Surface Roughness | Ra ≤ 1.6~3.2μm |
