Introduction to the 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 have high rigidity and high load-bearing capacity, while achieving a good combination of high speed performance and small cross-sectional height. The small cross-sectional height allows for a smaller wheelbase when assembling multiple axes. Since cylindrical roller bearings can compensate for the length changes of mating parts that are subject to heat restrictions, they are an ideal choice for floating bearings.
