Bearings - Single Row Ball - Flanged - Precision - Extended Inner

Extended Inner Precision Flanged Single Row Ball Bearings. Single row radial ball bearings with flanges and extended inner rings (wide inner rings).

Single row radial ball bearings are arguably the most common, widely used type of bearing. They consist of an inner ring, an outer ring, a set of balls, and a cage that retains the balls in a circular path.
Single row radial ball bearings are commonly used in a wide range of applications, including electric motors, fans, pumps, gearboxes, agricultural equipment, appliances, and automotive components.
They are versatile, cost-effective bearings that provide reliable support for radial loads and some axial loads in one direction. An expanded range may be available on special order. Please enquire.
If the size you require is not available, you might consider using a standard bearing with shim washers.
