Angular contact ball bearings are classified with different accuracy and tolerance ranges for ball bearings on the ABEC bearing rating scale. A higher ABEC number indicates that the bearing tolerances are tighter. When searching for your angular contact bearing, it is important to consider aspects like operation specifics and dimensions.
Operating Specifics for Angular Contact Ball Bearings
· Static radial load: the maximum radial load the bearing can withstand without succumbing to the pressure
· Dynamic radial load (calculated constant radial load): the amount of load a set of similar bearings with fixed outer rings can withstand against a rating life of one million revolutions of the inner ring
· Rated speed: Grease lubrication gives a lower rated speed for bearings as compared to a bearing with oil lubrication
There are a variety of materials used in the construction of the angular contact bearing, including stainless steel, ceramic, and plastic. This type of ball bearing can also be plated. The materials that are commonly used to plate these bearings include chrome and cadmium.
