Do you know why the spindles need to add double row cylindrical roller bearings?Let's learn it together with Henan Weichuang Bearing Precision Technology Co., Ltd.
Generally, the double row cylindrical roller bearing bearing has the advantages of compact structure, large rigidity, large bearing capacity, small deformation after being loaded, and the like, and is particularly suitable for the spindle support of the machine tool.
1. Firstly, for the machine tool spindle, it mainly bears radial load, and sometimes the spindle speed is required to be high. Therefore, the required bearing must have a large radial bearing capacity, and the structure is compact, that is, the shape is small.
2. The double row can effectively improve the radial bearing capacity. The cylindrical roller is in line contact with the inner and outer rings of the bearing, which can also improve the bearing capacity.
3. Cylindrical roller bearings provide large radial bearing capacity (compared to ball bearings) when the outer diameter is small, which can effectively reduce the limitation of centrifugal force on the spindle speed.
