Precision Knurled Shaft
Product Introduction
Precision knurled shaft is a shaft part, whose surface is formed into regular convex patterns through precision knurling process. It has high matching accuracy, anti-slip and high mechanical stability. It is widely used in motors, printing equipment, home appliances and transmission assembly fields.
Product Features
Strong Corrosion Resistance
Precision knurled shaft adopts SUS304 or 316 stainless steel, which has excellent corrosion resistance and will not rust even in salt spray, high humidity or seaside environment for a long time.
High Strength And Fatigue Resistance
After tempering or carburizing heat treatment, the surface hardness of the knurled shaft can reach HRC55, the tensile strength exceeds 600MPa, it can withstand repeated load impact, and the service life of the whole machine exceeds 8 years.
Strong Anti-slip Bite
The knurled structure is mechanically pressed with a depth of 0.2~0.3mm to form regular convex patterns, which strongly bite with plastic or metal holes, and the anti-rotation slip effect is increased by more than 3 times, especially suitable for high torque connection.
Product Application
Electronic Equipment Industry
In the electronic equipment industry, precision knurled shafts are used as the core rotating parts of small motors and micro motors. Their knurled surfaces increase friction, ensuring stable power transmission during high-speed operation, avoiding slipping, and ensuring stable operation of the equipment.
Automobile Manufacturing Field
In the automotive manufacturing field, precision knurled shafts play a role in engines, transmissions, and steering systems. Power conversion is achieved in the engine, the transmission assists in shifting, and the steering system accurately controls the direction, improving driving performance and safety.

Frequently Asked Questions
Q: What fields are precision knurled shafts mainly used in?
A: It can be widely used in mechanical processing, electronic equipment, toys, automobiles and other fields. In the mechanical field, it is used to transmit torque and increase friction; in electronic equipment, it is used as a rotating shaft; in toys, it is used to achieve specific movements; in automotive parts, it is used to improve performance.
Q: What should be paid attention to when installing the knurled shaft?
A: Ensure the coaxiality of the center of the shaft and the mating parts to avoid eccentricity. Avoid damaging the shaft surface and the knurled part during installation, tighten the connecting parts according to the specified torque, and ensure a firm installation.
Q: What should I do if the knurled shaft is worn during use?
A: Minor wear can be repaired by grinding; severe wear requires replacement. Daily lubrication and maintenance should be done to reduce wear, choose a suitable lubricant and add it regularly.
Q: How to clean and maintain the knurled shaft?
A: Regularly wipe the surface dust and debris with a clean soft cloth, and clean it with a suitable cleaning agent when there is oil. For shafts with complex structures, some parts can be disassembled for deep cleaning when necessary.
Q: What are the advantages of precision knurled shafts compared to ordinary shafts?
A: Knurling increases surface friction, performs better in transmitting torque and preventing slipping, can adapt to scenarios with high requirements for torque and stability, and can achieve specific functions through pattern design.
Q: What will affect the performance of High-precision knurled shaft in a high temperature environment?
A: High temperature may cause the shaft material to expand and deform, affecting the accuracy; accelerate the aging of lubricants, reduce the lubrication effect, increase wear, and even cause damage to the knurled parts.
Q: What are the key steps in the production process of High-precision knurled shaft?
A: The production process includes raw material processing, shaft turning, knurling, heat treatment (to improve hardness and strength), surface treatment (rust prevention, etc.), and each step requires strict control of parameters to ensure quality.
Q: How to detect whether the quality of precision knurled shaft is qualified?
A: By measuring indicators such as dimensional accuracy, surface roughness, and hardness, check the uniformity and clarity of the knurled pattern, and conduct torque testing and flaw detection to judge the quality.
Q: If the precision knurled shaft vibrates, what may be the cause?
A: The reasons may be improper installation leading to eccentricity, shaft imbalance, bearing wear, uneven load, resonance, etc., which need to be investigated and solved in a targeted manner.
Q: How to ensure the stability of precision knurled shafts when they are running at high speed?
A: Ensure that the shaft is well balanced, select appropriate bearings and lubrication systems, control installation accuracy, reduce vibration and noise, and perform dynamic analysis on the shaft to optimize the structural design.
