Ball Bearings

Used and surplus ball bearings for sale. MRO Exchange carries a rotating selection of industrial ball bearings available for immediate purchase and fast nationwide shipping.

Ball bearings are the most widely used bearing type in industrial applications. Their ability to handle both radial and axial loads in a compact, low-friction package makes them the default choice across a broad range of rotating equipment from electric motors and gearboxes to CNC spindles, pumps, and conveyor systems. Deep groove ball bearings cover the majority of general industrial applications where moderate radial and axial loads are present. Angular contact ball bearings, also called contact bearings, are engineered for applications combining significant axial load with radial load, making them the standard choice for CNC machine tool spindles and precision rotating assemblies where axial rigidity is critical.

Selecting the correct ball bearing requires matching bore diameter to the shaft, outer diameter and width to the housing, and load rating to the application requirements. For precision applications like CNC spindles, accuracy class and preload specification are additional considerations that must match the original bearing specification. MRO Exchange lists manufacturer, part number, and condition for every ball bearing in our inventory.

Every ball bearing listed on MRO Exchange ships nationwide from our facility in Illinois at prices well below new distributor cost.
