This is a super-precision angular contact ball bearing in the 65 mm bore x 100 mm outside diameter x 18 mm width envelope — the ISO 7013 size.
The suffix string decodes as follows: C is a 15 degree contact angle, T is the machined cage, DUM is duplex universal with medium preload, P4 is ABEC 7 precision, and -1/2PR means HALF OF A PAIR.
Check that last point before ordering, because DUM describes the behaviour of two bearings mounted together while 1/2PR means you are buying one of them — a complete duplex medium-preload set requires two.
Universal grinding is what makes that work: any two matched halves stack back-to-back (DB), face-to-face (DF) or in tandem (DT) and arrive at the specified preload with no shimming or custom grinding.
Medium preload sits between light and heavy, giving more axial rigidity and tighter shaft location than light without the heat generation that limits heavy preload at high speed. The 18 mm width in a 65 mm bore makes this a slim-section spindle bearing, chosen where axial space is tight.
RHP is now part of NSK, and this part also carries the designations B 7013 X2 TA DUM EP5 and cross-references to Timken 2MM9113WI CR DUM. Typical duty is machine-tool spindles, precision grinders, high-speed motion control and rotary tables.
