A Consolidated NN3011KMSP5 double-row cylindrical roller bearing with a 55 mm tapered bore, a 90 mm outside diameter and a 26 mm width. It is a precision spindle bearing with a machined brass cage, ground to ABEC 5.
NN — double-row cylindrical roller design, rollers guided by the inner ring, outer ring ribless3011 — 30 series, 55 mm bore, 90 mm OD, 26 mm widthK — 1:12 tapered boreM — machined brass cageS — Consolidated execution letter, retained as a search termP5 — precision class 5, equivalent to ABEC 5
Two rows of cylindrical rollers give a long total contact line in a narrow section, so the bearing carries very high radial load and holds the shaft radially stiff. The design is non-locating: the ribless outer ring lets the shaft grow axially through the bearing as it heats, and axial location comes from a thrust or angular contact bearing elsewhere in the spindle. An NJ or NUP cylindrical bearing locates the shaft axially and a single-row NU has half the roller complement, so neither substitutes for this design.

Supplied as 1 Pc, bearing only.
The 1:12 tapered bore seats directly on a matching tapered spindle journal. Radial internal clearance is set by how far the inner ring is drawn up the taper, so mounting position is the clearance adjustment. This design does not use an adapter sleeve.
Genuine equivalents are P5 double-row tapered-bore cylindrical roller bearings in the same 55x90x26 mm envelope with a machined cage: SKF NN3011 KTN9/SP, FAG NN3011-AS-K-M-SP, NSK NN3011TBKRE44CC1P4 and URB NN3011K. The straight-bore NN 3011 is a related size rather than an interchange, because it needs a cylindrical shaft seat and gives no clearance adjustment.
