High-precision stainless steel bushings 304 Trustworthy CNC machining wear-resistant parts
Ganyuan Factory boasts over twenty years of experience in manufacturing precision bushing components, specializing in providing CNC machining solutions for various industries, including straight bushings, flange bushings, tapered bushings, bearing bushings, and custom-made stainless steel bushings. Equipped with high-precision CNC lathes, internal and external grinding machines, and a complete set of roundness testers, roughness testers, and pneumatic measuring instruments, the factory ensures that the entire process, from material pretreatment and precision forming to final grinding, achieves micron-level dimensional tolerances, excellent surface integrity, and stringent coaxiality and perpendicularity requirements.
We focus on one-stop precision manufacturing from raw materials to finished products, and are dedicated to the research and development and production of CNC-machined stainless steel bushings. Leveraging advanced CNC turning, precision grinding, and professional heat treatment processes, we transform high-quality stainless steel materials into critical transmission and support components with precise inner bores, smooth outer surfaces, and excellent corrosion and wear resistance.

I. CNC Machining of Stainless Steel Bushings Product Description:
Based on the specific working conditions of the bushings, we scientifically select stainless steel materials with different properties, such as 304, 316, 440C, and 17-4PH, and manufacture them through precision CNC turning, grinding, drilling, and oil groove machining. Stainless steel is renowned for its excellent strength, hardness, corrosion resistance, and achievable high-gloss surface finish. Through optimized machining strategies and online compensation technology, we ensure that the inner bore diameter tolerance, outer diameter tolerance, wall thickness uniformity, and oil groove position of the bushings all meet strict tolerance zones.
II. Our precision-manufactured stainless steel bushings are committed to meeting three core performance requirements:
Precision internal and external cylindrical grinding ensures that the bushing’s dimensional tolerances reach H6/h5 grade, with roundness and cylindricity controlled at the micron level. This provides an ideal uniform clearance for the rotating shaft, ensuring the establishment of a lubricating oil film, effectively reducing friction and wear, and improving operational smoothness.

II. Excellent wear resistance and corrosion resistance
The high hardness of the stainless steel material, achieved through heat treatment, gives it excellent wear resistance, enabling it to withstand the rotational friction of the shaft for extended periods.
1. CNC Machining of Stainless Steel Bushings: A Systematic Process Chain Ensuring Performance and Consistency
We have established a comprehensive quality control system covering the entire process, from material selection and pretreatment, multi-process machining planning, online dimensional and geometric tolerance inspection, to surface integrity analysis, oil groove and oil hole burr removal, cleanliness control, and rust-proof packaging. We pay particular attention to deformation control during the machining of thin-walled bushings, ensuring the coaxiality of inner and outer circles, and dimensional consistency in mass production.
We are committed to becoming your trusted partner in the field of high-performance stainless steel sliding components through our deep knowledge of stainless steel materials, professional bushing manufacturing technology, and a quality culture centered on reliability. From application condition analysis and material and process selection consultation to sample production, performance testing, and mass supply, we provide professional, rigorous, and high-performance manufacturing solutions throughout the entire process, providing core guarantees for the smooth, reliable, and long-term rotation and support of your precision equipment in harsh environments.
