Ball Bearing Collar
Ball Bearing Shaft Collars are similar to our Standard stainless and aluminum shaft collars. They are 303 stainless steel and have one set screw and a pre-drill at 90 degrees. On one side of the collar they have a small journal which is designed to mate with the inner race of ball bearings. This permits the collar to preload the ball bearing without interference contact with the outer race of the bearing and thus eliminating the installation of a shim spacer. They have precision bores held to +.0005” tolerance. Inch and metric bores are available from 5/64” to 1 inch.
