Allied Systems Company Y010190 Ball Bearing Race

Allied Systems Company Y010190 Ball Bearing Race is the annular track element of a large-diameter ball bearing assembly, identified by the part number Y010190 and the DR2B2 designation. The race measures 2 1/2 by 13 1/2 inches, specifying the inner/outer dimensions that define the bearing surface and the envelope for rolling elements. This component functions as the race surface that interfaces with the accompanying ball set and mating inner or outer race in compatible bearing housings and shafts, enabling controlled rotation under load in industrial equipment. The DR2B2 tag ties the race to Allied's catalog reference for this size class, aiding cross-reference with service manuals or procurement records when sourcing replacement parts. Typical applications for large-diameter bearing races include conveyors, heavy machinery, and gearbox assemblies where a matching set of race, balls, and companion race is used to form a complete bearing. Buyers should confirm fitment against Allied Systems documentation or NSN cross-references to ensure correct mating parts and shaft dimensions before replacement. This description conveys the exact Y010190 race and its 2.5 in × 13.5 in footprint, helping buyers verify the correct Allied Systems part for applications requiring this specific size without speculating on material, tolerances, or additional features beyond the confirmed dimensions and identifier.
