Spindle bearings are key to the precision and performance of CNC lathes. Their accuracy depends on two main factors: Rotational accuracy: radial/axial runout of rings Dimensional accuracy: inner/outer diameter tolerances Here are the main factors that affect bearing accuracy: 1. Manufacturing Errors Raceway roundness errors cause uneven load, vibration, and wear. Surface roughness or waviness affects lubrication, wear, and stability — especially at high speeds. 2. Assembly Issues Misaligned shafts or housings deform raceways and reduce stiffness. Incorrect preload or clearance leads to instability, friction, and heat. Non-perpendicular mounting surfaces cause tilting and uneven loading. 3. Design and Material More rollers reduce runout, but with diminishing returns. Larger radial clearance increases runout. Poor heat treatment causes early wear and hardness loss. 4. Operating Conditions Heat from friction changes dimensions and affects preload. Poor lubrication increases wear and noise; too much grease causes overheating. Dynamic loads (e.g., cutting forces) increase stress and reduce life. Tips for Better Accuracy Use high-precision bearings with low roughness and waviness. Ensure correct alignment and controlled preload during installation. Choose suitable materials and lubrication for your application. Monitor temperature, vibration, and wear regularly. Summary To keep spindle bearings accurate:

At Beining Technology, we specialize in providing customized bearing solutions that meet the unique needs of industrial applications. One example is our successful customization of the 6816 deep groove ball bearing used in drive wheel reducers.
