Category Information

Bearings - Single Row Ball - Unflanged - Precision - High Speed Cage

High Speed Cage Precision Unflanged Single Row Ball Bearings. This product group includes bearings with cages for high speed applications, including phenolic, nylon and polyamide.

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.
Bearings in this group have various types of high speed cages.
Speed ratings range from 20 percent to 80 percent increase on standard cage types.
See individual datasheets, available on request.
Items with high speed cages usually have the suffixes T9H, TNH, TW or KC
This category does not include ceramic hybrid bearings with high speed cages. These are listed under Bearings - Ceramic Hybrid
