Bearings - Single Row Ball - Unflanged - Precision - Ceramic HybridCeramic Hybrid Precision Unflanged Single Row Ball Bearings. Steel Races with Si3N4 Ceramic Balls
- 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 minimal axial load in one direction. An expanded range may be available on special order. Please enquire.
- Bearings with steel races and ceramic balls.
- For standard bearings, the balls are usually one of the first components to show wear.
- Ceramic balls are harder than steel and do not wear as easily.
- Items with high speed cages have the suffixes T9H, TNH, TW or KC
