China OEM Turbocharger Thrust Bearing - NN3012KTN/SP Super-precision Double-row cylindrical roller bearing – CWL Detail:

These bearings are therefore particularly well suited for machine tool spindles where the bearing arrangement must accommodate heavy radial loads and high speeds, while providing a high degree of stiffness, double row bearings are more suitable for heavier loads.

Double-row cylindrical roller bearings have two structures: cylindrical inner bore and conical inner bore (the bearing rear code plus K). The conical inner hole can also play the role of micro-adjustment of the clearance, and can simplify the structure of the positioning device and facilitate installation and disassembly.

Commonly used double row cylindrical roller bearings have the following types: NN series, NNU series, and NNF series.Tolerances: SP, UP, SP and UP for 1:12 tapered bore.
