Category Information
Bearings - Single Row Ball - Unflanged - Precision - High Speed CageHigh 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
