Precision Long Shaft
product introduction
Precision long shaft is a long shaft component made of stainless steel material. It is widely used in various mechanical equipment to transmit power or support rotating parts.
product Features
Small Dimensional Tolerance
The precision long shaft adopts high-precision CNC machining, and the shaft diameter tolerance is controlled to ±0.003 mm. High precision ensures that the gap is extremely small when it is installed on components such as bearings or couplings, thereby reducing shaking and wear during operation and extending the overall life of the equipment.
High Straightness
The long shaft is first tested for straightness by laser equipment, and the shaft surface is straightened by roller extrusion, so that the straightness deviation of the entire shaft is controlled to ≤0.01mm/m, effectively reducing the vibration and noise caused by axis deviation.
High Surface Finish
The stainless steel long shaft adopts steps such as rough grinding, semi-fine grinding and mirror polishing, and finally the shaft surface roughness is controlled to Ra 0.2–0.4 μm, which can effectively reduce the friction between parts, improve operation efficiency and extend the service life of the equipment.
Product Applications
Automated Production Line
The long shaft can be used as a conveyor drive shaft or a robot arm connecting shaft.
Food Processing Equipment
The precision long shaft can be used as a stirring shaft, cutting shaft or conveying shaft.
Medical Equipment
The precision long shaft can be used as a rotating guide shaft or bed lifting shaft in surgical equipment.
Water Treatment And Pump Equipment
The long shaft can be used as a water pump coupling or impeller main shaft.
Printing And Packaging Machinery
The stainless steel long shaft can be used as a roller shaft or a feeding shaft.

FAQ
Q: What are the common materials for precision long shafts?
A: Common materials include 304, 316 and 17-4PH stainless steel, of which 304 is suitable for most anti-rust requirements, 316 has stronger corrosion resistance, and 17-4PH has higher strength and hardness.
Q: Can precision long shafts be customized?
A: Yes. We support customization according to drawings or samples, including parameters such as number of teeth, module, shaft diameter, length, keyway, hole position, etc.
Q: Does it support sample proofing?
A: Yes. You can provide drawings or technical requirements, and we will first process samples for you to confirm the size, structure and assembly effect, and then mass production after confirmation.
Q: Can hardness or strength test reports be provided?
A: Yes, Rockwell hardness test results can be provided routinely. If required, tensile strength, yield strength and other test reports can also be provided according to customer-specified standards.
Q: Is the long shaft easy to deform during transportation? How to package?
A: To prevent deformation during transportation, we use customized thickened paper tubes or wooden boxes for packaging, and use fixed brackets to protect both ends to ensure that there is no bending damage during transportation.
Q: Do you provide supporting parts such as bearings and couplings?
A: We provide one-stop procurement services, and optional supporting bearings, couplings and other parts are available.
Q: Can you mark or engrave on the surface of the shaft?
A: Yes, laser marking, inkjet coding or engraving are supported, which are often used to mark dimensions, batch numbers, brand logos, etc., to facilitate subsequent identification and traceability.
Q: What types of connections are suitable for stainless steel long shafts?
A: Suitable for key connection, threaded connection, spline connection, expansion sleeve connection and other methods.
Q: How long is the service life of stainless steel long shafts usually?
A: Under the conditions of reasonable material selection, normal load and good lubrication, the service life can reach 5-10 years or even longer, which is much higher than ordinary carbon steel shafts.
Q: How much load can a stainless steel long shaft withstand?
A: The load-bearing capacity of the shaft depends on the material, diameter and processing technology. Taking a 304 stainless steel shaft with a diameter of 25mm and a length of 1000mm as an example, its static load can reach 3000N. The specific application needs to be combined with the use scenario for engineering calculation.
Q: Is the stainless steel long shaft magnetic?
A: Commonly used 304 and 316 stainless steel long shafts are non-magnetic or weakly magnetic, but the cold working process may cause slight magnetism. If you need to be completely non-magnetic, you can specify it and we can provide full demagnetization service.
