Stainless Steel Knurled Shaft
Product Introduction
Stainless steel knurled shaft is a precision transmission shaft with knurled texture on the surface, high strength, corrosion resistance and anti-slip performance. It is used in automation equipment and mechanical structures to achieve efficient fixation and transmission.
Product Features
Excellent Corrosion Resistance
Stainless steel knurled shaft is made of 304 or 316 stainless steel, containing more than 18% chromium, and can be used continuously for more than 5 years without rusting in humid, acidic, alkaline, and salt spray environments.
High-strength Load-bearing Structure
The tensile strength of the stainless steel knurled shaft is 520MPa, and the yield strength exceeds 205MPa. It can withstand high-load conditions such as high-speed rotation and mechanical impact for a long time without deformation.
High-precision Dimensional Control
The diameter tolerance of the knurled shaft is controlled at ±0.003mm, and the straightness is ≤0.05mm/m, ensuring high matching accuracy with bearings and other components, and more stable and reliable operation.
Anti-slip Structure Design
The surface knurling depth is 0.2~0.5mm, which can increase the friction by more than 40%, effectively preventing slipping or loosening in high vibration or rotation scenarios, and improving structural stability.
Product Application
Automation Equipment
In automation equipment, stainless steel knurled shafts are used in fixtures, conveying devices, and transmission mechanisms to achieve high friction positioning and stable rotation to prevent parts from slipping.
Precision Instruments And Equipment
In optical detectors and medical equipment, knurled shafts play a connecting and supporting role.
Mechanical Structure Transmission
In packaging machines, printing equipment, and feeding equipment, stainless steel knurled shafts transmit power while preventing slipping and positioning, and bear high-frequency rotation and impact.
Home Appliance And Tool Manufacturing
In power tools and kitchen appliances, knurled shafts are used as transmission or connecting components to prevent loosening due to vibration after long-term use.

Frequently Asked Questions
What is the working principle of stainless steel knurled shaft?
The stainless steel knurled shaft uses the knurling tool to squeeze the concave and convex texture on the shaft surface, and uses the texture to increase the friction between the contact parts to achieve stable transmission. It is often used in scenes where torque needs to be accurately transmitted or easy to hold and operate.
In what fields are stainless steel knurled shafts commonly used?
It is widely used in mechanical manufacturing, electronic equipment, medical equipment and other fields.
What points should be paid attention to when installing stainless steel knurled shafts?
During installation, the coaxiality of the shaft and the mating parts must be ensured to avoid eccentricity causing running vibration. Clean the installation part, apply an appropriate amount of lubricant, tighten the fixings according to the specified torque, and pay attention to protecting the knurled surface to prevent damage.
How to clean the stainless steel knurled shaft on a daily basis?
For daily cleaning, you can wipe the surface dust and oil with a clean soft cloth. For stubborn stains, you can use a neutral detergent to dilute and wipe, then rinse with clean water and wipe dry, and avoid using corrosive detergents to damage the shaft surface.
How to repair the wear of stainless steel knurled shafts?
Minor wear can be restored to surface finish by polishing; when the wear is severe, it can be repaired by electroplating, spraying wear-resistant coating and other methods, and a new shaft can be replaced if necessary to ensure the normal operation of the equipment.
What are the advantages of stainless steel knurled shafts compared with knurled shafts made of other materials?
Compared with carbon steel knurled shafts, stainless steel knurled shafts are more corrosion-resistant and less prone to rust; compared with aluminum alloy knurled shafts, they have higher strength and hardness, can withstand greater loads, and are suitable for a wider range of working environments.
How to lubricate and maintain stainless steel knurled shafts?
Choose a suitable lubricant, such as lubricating oil or grease, according to the working environment and load. Apply or replenish lubricants regularly, clean the lubrication parts, prevent impurities from entering and affecting the lubrication effect, and reduce shaft wear.
What factors affect the service life of stainless steel knurled shafts?
The service life is affected by factors such as load size, working environment, lubrication conditions, and maintenance. Long-term overload, harsh environment, insufficient lubrication or lack of maintenance will accelerate the wear of the shaft and shorten its service life.
How to repair the wear of stainless steel knurled shafts?
Minor wear can be restored to surface finish by polishing; when the wear is severe, it can be repaired by electroplating, spraying wear-resistant coatings, etc., and a new shaft can be replaced if necessary to ensure the normal operation of the equipment.
What are the manufacturing processes of stainless steel knurled shafts?
The main manufacturing processes include raw material cutting, turning and forming, knurling, heat treatment (to improve hardness and strength), surface treatment (such as polishing, passivation), etc. Each link must strictly control the quality to ensure that the performance of the shaft meets the standards.
