Set Screw Shaft Collars
Aluminum and Stainless Steel Shaft CollarsMaterial is an important consideration in mechanical performance. Aluminum shaft collars are lightweight and have a chromic acid anodize finish to prevent oxidation. Precision shaft collars are heavier but more durable than aluminum. All our shaft collars feature stainless steel socket head set screws.
Precision Grade Standard Stainless Steel Shaft CollarsPrecision 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. Precision Shaft 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.
Commercial Grade Stainless Steel Shaft CollarsCommercial Shaft Collars are made in non-magnetic 303 stainless steel. These stainless steel shaft collars have commercial bores held to +.0005” tolerance. Inch and metric bores are available from 5/64” to 2-3/8”. These Shaft Collars are supplied with one set screw.
Ball Bearing Shaft Collars Stainless Steel and AluminumBall Bearing Shaft Collars have one set screw and a pre-drill at 90 degrees. One side of the collar has a small journal 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, eliminating the installation of a shim spacer. Ball bearing shaft collars have precision bores held to +.0005” tolerance. Inch and metric bores are available from 5/64” to 1 inch.
Four Screw Shaft CollarsFour Screw Shaft Collars are supplied with four set screws at 90 degrees apart. They have a looser bore tolerance than our Precision or Ball Bearing Collars and do not have a pre-drill hole for permanent installation. Four Screw Shaft Collars are generally narrower in width and are supplied in 303 stainless steel or anodized aluminum. Available bore sizes range from 1/8” to 5/8” and from 2.5mm to16mm.
