Bearings equipped with several rows of rolling elements are different, cylindrical roller bearings can be divided into single row, double row and multi-row cylindrical roller bearings. Where the application is more cage single row cylindrical roller fatigue testing machine bearings. In addition, there are single or double row cylindrical roller filled and other structures roller contact angle measurement bearings.
Single row cylindrical roller bearings under the ring wall is divided into N-type, NU type, NJ-based, NF type and NUP type. Cylindrical roller bearings under radial load capacity, according to the structure of ring wall can withstand a certain one-way or two-way axial load.
NN and NNU type double row cylindrical roller bearings compact structure, strong rigidity, large carrying capacity, the small deformation under load, mostly for supporting the machine spindle.
