Cylindrical Roller Bearings

Machine tool spindles have extremely high requirements on bearing rotation accuracy. High-precision cylindrical roller bearings have high rigidity and high load-carrying capacity, as well as high rotational speed and small cross-sectional height. The small cross-sectional height enables a smaller wheelbase for multi-axis assembly. Cylindrical roller bearings are ideal for non-locating bearings due to their ability to compensate for length variations of mating components that are thermally limited.
High-precision cylindrical roller bearings used in machine tools are available in a variety of structures. Dimension series 19 and 10 are single-row bearings, while dimension series 30 and 49 are double-row bearings. The bore diameter and outer diameter of single-row and double-row cylindrical roller bearings are exactly the same within each diameter series.
Tapered bore high-precision cylindrical roller bearings are marked with the suffix symbol K and are produced with a taper angle of 1:12. Mainly used in dry machine tool manufacturing, the tapered hole can adjust the radial clearance and preload through the axial movement of the shaft tapered support surface during assembly.
