Category Information
Bearings - Single Row Ball - Unflanged - Precision - Chrome SteelChrome Steel Precision Unflanged Single Row Ball Bearings. Chrome steel radial ball bearings.
- 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.
- Standard single row radial ball bearings.
