Schematic Diagram:

Parameters:

HGT KA angular contact ball bearing bore diameters ranging from 1.000 inches to 20.000 inches.  Cross-section range from 0.1875 X 0.1875 inch to 1.000 X 1.000 inch. In these series, the materials of rings could be GCr15 and stainless steel. Please pay attention to the detailed reference table when you choose the bearings:

The open style angular contact Bearing is used widely in the Textile printer, Medical devices, Rotary tables, Radar, Communication, Aircraft, Aerospace, Astronomy instrumentation, Industrial robotics, etc., where needed bearings that have higher capacity, lightweight, and have low friction.  They are used to advantage in applications where space and weight considerations are meaningful.
