Shaft Collars

Set screw shaft collars are used to position components on shafts. Ondrives.US manufactures precision 303 stainless steel shaft collars and aluminum shaft collars.

Standard Shaft Collars are made in non-magnetic 303 stainless steel. These stainless steel shaft collars have precision bores held to +.0005” tolerance. Inch and metric bores are available from 5/64” to 16mm.  Standard Collars are supplied with one set screw and a spot or pre-drill at 90 degrees from the screw. Use the pre-drill to drill through the collar and shaft to install a dowel or spring pin.

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.                           

Four Screw Shaft Collars are supplied with four set screw at 90 degrees apart. They have a looser bore tolerance than our Standard or Ball Bearing Collars and they do not have a pre-drill hole for permanent installation.  Four Screw Collars are generally narrower in width and are supplied in 303 stainless steel or anodized aluminum. These aluminum and stainless steel clamp collars have available bore sizes ranging from 1/8” to 5/8” and from 2.5mm to16mm.
