The reason why CNC-machined bearings occupy a central position in the field of precision transmission stems from their outstanding advantages in machining accuracy, structural stability, service life, and adaptability. Each of these characteristics precisely meets the stringent requirements that high-end equipment places on transmission components.
Advantages
With their exceptional performance, CNC-machined bearings provide stable and reliable power transmission assurance for various types of equipment, driving the mechanical manufacturing industry toward higher precision and greater efficiency.
Ultra-high machining accuracy
CNC machining utilizes high-precision numerical control systems to achieve micron-level accuracy, with surface roughness as low as Ra0.4μm or below.
Exceptional structural stability and superior load-bearing capacity
CNC machining enables precise control over bearing structural parameters-such as raceway curvature radius, contact angle, and cage pocket dimensions-ensuring uniform contact between rolling elements and raceways while effectively distributing load pressure.
Superior surface quality for extended service life
During the CNC machining process, the relative motion between the tool and workpiece remains smooth with consistent cutting forces. This results in bearing surfaces free from scratches and burrs, while the uniform microscopic texture of raceways effectively reduces friction wear between rolling elements and raceways
Excellent adaptability to complex structures
CNC multi-axis machining (e.g., 5-axis CNC machining centers) easily handles specialized bearing configurations-such as flanged bearings, full-complement roller bearings, and combined bearings-that are challenging for traditional manufacturing methods.
Materials
CNC lathe turning is compatible with a wide range of metal and plastic materials, including but not limited to: Stainless Steel (304, 316, 430, #45 etc.) ; Aluminum Alloys (6061, 7075, etc.); Copper, Brass, bronze; Titanium Alloys; Plastics (POM, Nylon, PEEK, PTFE)
Surface Finish
We can provide paint, polish, silk-screen printing(logo custom), anodize, electronic plating, sandblast, powder coating, laser engraving, etc. If you have the requirement on color, you can provide us the pantone code, our colleague will help to process with high quality treatment.
Process
Firstly, we will assign programming tasks to the CNC engineering team, who will program and arrange CNC machining based on the 3D drawings.
After processing, surface treatment will be carried out according to the customer's requirements.
After all the parts have been completed, we will measure and verify them according to customer's information or drawings.
This step is quality control. We have a dedicated quality inspection department to ensure that all products meet the drawing requirements before shipment. If there have impacted parts, we will remake and check again to ensure every step is right.
After passing the inspection, we will proceed with packaging and then contact the freight forwarder for shipment. We will report every step of producing, aiming to provide customers with quality assured products.
