Spherical roller bearing and shaft concentricity of what is required
First of all, choose "C" precision bearings (B class accuracy is highest, I do not know whether the current national standard);
First of all, choose "C" precision bearings (B class accuracy is highest, I do not know whether the current national standard); secondly, according to your shaft load to decide. Can not use self-aligning bearings, you can consider "tapered roller bearings."".
