Product Features
1. Ultra-high precision, stable transmission
Using five-axis linkage CNC machining center and ultra-precision grinding technology, the shaft diameter size accuracy can reach IT5-IT6 level, the cylindrical error is ≤0.001mm, and the surface roughness is Ra≤0.2μm. The precise manufacturing process ensures that the shaft and bearings, gears and other components are perfectly matched, the transmission is smooth and vibration-free, and the equipment operation noise and energy consumption are effectively reduced.
2. High strength, long life
Using high-strength materials such as 42CrMo and 30CrMnTi alloy steel, after quenching, tempering and other heat treatment processes, the tensile strength can reach more than 1200MPa and the hardness can reach HRC50-60. The shaft has excellent wear resistance and fatigue resistance, can withstand high speed and heavy load conditions, and has a service life of more than 10 years.
3. Strong corrosion resistance and wide application
Stainless steel shaft parts (such as 304, 316L) have excellent anti-rust and anti-corrosion capabilities after passivation treatment; titanium alloy shafts can still maintain stable performance under extreme environments such as high temperature, strong acid and alkali, and are suitable for special fields such as chemical industry and marine engineering.
4. Customized design and flexible adaptation

Support customization of shaft diameter, length, keyway, thread and other parameters according to customer needs to adapt to the installation and transmission requirements of different equipment. Some common specifications and parameters are as follows:

Type	Material	Diameter range (mm)	Length range (mm)	Main application scenarios

Product Details
1. Material Type
Alloy steel: Alloy steels such as 42CrMo and 30CrMnTi have high strength and toughness after heat treatment, and are suitable for heavy-loaded and high-speed transmission spindles, such as automobile engine crankshafts and machine tool spindles.
Stainless steel: 304 stainless steel has good comprehensive performance and is suitable for general industrial environments; 316L stainless steel adds molybdenum elements, which has stronger corrosion resistance and is often used in food, medicine, and water treatment equipment.
Titanium alloy: Titanium alloy has low density, high strength, and excellent high temperature and corrosion resistance. It is widely used in aerospace engine shafts and deep-sea exploration equipment transmission shafts.
2. Manufacturing process
CNC machining: Through turning, milling, boring and other processes, the outer circle, inner hole, thread, keyway and other structures of the shaft are accurately machined to ensure dimensional accuracy and surface quality.
Ultra-precision grinding: High-precision grinders and grinding processes are used to finely process the key parts of the shaft to further improve the surface finish and dimensional accuracy.
Surface treatment: We provide blackening, hard chrome plating, nitriding, nickel plating and other surface treatment processes to enhance the wear resistance, rust resistance and aesthetics of the shaft.
