The spindle of a machine tool has extremely high requirements for the rotational accuracy of the bearing. 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. This issue will introduce the structural characteristics of cylindrical roller bearings and tapered roller bearings through a video. For details, please click on the video below to learn~
