Product Overview
Guangzhou Juhong Industrial Co., LTD., relying on over 30 years of experience in precision manufacturing, specializes in the production of high-performance precision embossed shafts (also known as knurled shafts). This product is made of high-quality steel and processed with precise techniques. With its outstanding transmission performance, excellent wear resistance and stable dimensional accuracy, it has become a key component for achieving reliable connection and efficient power transmission in micro-transmission systems. It is widely applied in various precision devices that require anti-slip, precise positioning and torque transmission.
Core features and advantages
Outstanding anti-slip transmission performance
Precision patterns: By using an independently developed process, uniform, clear and burr-free straight patterns, net patterns or other customized patterns are pressed on the surface of the shaft body, significantly increasing the friction coefficient and effectively solving the slippage problem during transmission.
Strong torque transmission: The optimized pattern design ensures a firm fit with matching parts made of plastic, metal or ceramic, achieving efficient and stable torque transmission.
Long-lasting durability and reliability
High-quality materials: Carefully selected high-strength carbon steel or stainless steel to ensure the sturdiness and toughness of the shaft body base material.
Advanced heat treatment: Through precise carburizing, quenching and tempering treatments, the product surface achieves high hardness (specific HRC range can be provided), while the core maintains good toughness, thereby achieving high wear resistance, fatigue resistance and long service life.
Strict precision control
Precision manufacturing: The entire process is numerically controlled to ensure that key dimensions such as the diameter, true roundness, straightness and coaxiality of the steps of the shaft meet strict tolerance requirements (such as ±0.01mm).
Consistency guarantee: A complete quality inspection system ensures the dimensional stability and interchangeability of each batch of products, achieving worry-free assembly.
Comprehensive customization capabilities
Flexible Customization: We can provide you with all-round customization services based on your specific application requirements, including
Material selection: carbon steel, stainless steel, alloy steel, etc.
Pattern types: straight pattern, net pattern, twill pattern and other specific tooth shapes.
Size specifications: Customization is supported for various diameters, lengths and tolerance requirements.
