Angular Contact Ball Bearings

Angular Contact Ball Bearing Series. Many angular contact bearing manufacturers have three or more dimensional series to accommodate higher speeds or higher loads than “standard.” In particular, the most common series names are: ISO 18 Series - highest speed, lowest load bearings.Bearings Angular Contact Bearings are available with single-row or double-row radial ball bearings. Single-row bearings accommodate axial loads in 1 direction in addition to radial loads. Self-retaining unit with solid inner and outer rings and ball and cage assembly.

Angular contact ball bearings are often preloaded to enhance their rigidity and rotating performance. For high-precision matched pair angular contact ball bearings of class 5 or higher, which are used in machine tools and other precision equipment, the standard preload is specified in three levels: light , medium , and heavy.
