Our bearing NN3020MBKRE44CC1P4 is a Machine tool spindle roller bearing, also belongs to NSK Cylindrical roller bearing, double tow, tapered bore, with a machined brass cage, which can be separated into separate inner ring (NNU) and separate outer ring (NN), in most cases using NN series for machine tool spindle bearing, it is more convenient to install in the spine with the inner ring taper 1:12.

As we know, we also can get information from bearings themselves, just like NSK NN3020MBKRE44CC1P4: 30 indicates width series, 20 means inner dimensions, MB says machined bass cage, K indicates inner taper 1:12, RE44 inner structure code and CC1 means axial movement, etc. And this spindle bearing can interchange this bearing to SKF NN3020KTN9/W33P4, FAG NN3020B.MB.P4, NTN NN3020B.D1.P4.
