Why mechanical manual bearing SN series is only suitable for self-aligning ball bearings and roller bearings?
Or directly select UCP2 UCP3 series, as long as the right size, generally you can solve the difficulties of the choice.
If you want to according to the common 0 kinds of bearings, like 6201, you can select the SN2 SN3 series, the two series is designed for the general category of bearing.
Because the SN series of transposable elements, are generally filled with oil, suitable for harsh environment, high temperature and extreme environment, and habits, with the environment can only use precision is not high, but also on the use of environmental requirements is not high self-aligning ball bearings and spherical roller bearings, because they can allow the axial error, not neutral the gap is too large, a series of problems, and they take the lock sleeve after the installation is more convenient, so engineers use habits on selection of the above two!
