Structural features of cylindrical roller bearings and tapered roller bearings

Machine tool spindles have extremely high requirements for bearing rotation accuracy. High-precision cylindrical roller bearings not only have high rigidity and high load-bearing capacity, but also achieve a good combination of high-speed performance and small cross-sectional height. The small cross-sectional height makes the wheelbase smaller during multi-axis assembly. Cylindrical roller bearings are ideal for floating bearings due to their ability to compensate for thermally limited length changes in mating components.
