Consolidated Bearings Cylindrical Roller Bearing NN-3010-KMS P/5 50 x 80 x 23 mm

The Consolidated Bearings NN-3010-KMS P/5 is a double-row precision cylindrical roller bearing with a tapered bore and machined bronze cage, rated to ABEC 5 (ISO P5) tolerance class. Dimensions are 50 mm bore, 80 mm outside diameter, and 23 mm width. The KMS suffix designates the tapered bore profile with a 1:12 taper, and the M suffix confirms a machined bronze cage construction. The P/5 designation indicates ABEC 5 precision with ABEC 7 running accuracy equivalency per Consolidated's specification standard.

This bearing type is commonly used in machine tool spindle applications where high radial stiffness, precise running accuracy, and the ability to accommodate preload adjustment via tapered bore mounting are required. The double-row cylindrical roller design provides high radial load capacity in a compact envelope. The outer ring is separable from the inner ring assembly, facilitating installation and removal in tight housings.

Bearing dimensions and tolerance specifications conform to standard NN30 series geometry: 50 x 80 x 23 mm. The bronze cage provides guidance for the cylindrical rollers and is well-suited to higher-speed and higher-temperature operating environments compared to pressed steel alternatives. This unit is supplied in its original Consolidated Bearings box. The box label reads NN-3010-KMS P/5 with barcode 6 44075 0761. The inner ring is marked FAG NN3010ASX M.SP, indicating this bearing was manufactured by FAG (Schaeffler) and rebranded or cross-referenced by Consolidated.
