Decoding the designation

2MM — Timken/Fafnir super-precision class. ISO P4 / ABEC 7 running accuracy, with a 15° contact angle.

9326 — the ISO 71926 size: 130 mm bore, 180 mm outside diameter, 24 mm width.

CR — machined phenolic cage.

SUM — universally ground single bearing, medium preload. Any two of the same execution mount as a matched pair back-to-back, face-to-face or in tandem.

What these specs mean in practice

Contact Angle: 15°. A 15° angle favours speed and radial stiffness; a larger angle trades those for axial capacity.
