The URB NN3019KMSP51W33 is a double row precision cylindrical roller bearing manufactured by SC Rulmenti SA Barlad of Romania. Bore diameter measures 95 mm, outside diameter measures 145 mm, and width measures 37 mm. The designation breakdown identifies this as an NN30 series bearing with a tapered bore of 1:12 (K), a machined brass cage (M), spindle bearing precision class SP (equivalent to P5), high precision class 5 tolerance (51), and an outer ring lubrication groove with three holes (W33).

Double row cylindrical roller bearings of the NN30 series feature a solid inner ring with three integral ribs, a solid outer ring without ribs, two rows of cylindrical rollers, and a roller riding solid brass cage. The outer ring is separable from the inner ring and roller assembly, which simplifies mounting and dismounting on machine tool spindles. The double row design provides high radial load capacity, high radial stiffness, and high running accuracy within a compact axial envelope. The W33 lubrication feature allows grease or oil to be supplied through the outer ring directly to the rolling element zone.

Common applications include the main spindles of CNC lathes, milling machines, machining centers, grinding machines, and other rotating equipment that requires precise radial location combined with the ability to accommodate axial thermal expansion of the shaft. The tapered bore allows internal clearance to be adjusted by controlling the press in distance during installation. Item ships in original Bearings Limited factory box as pictured.
