Accu-Flange Collars

Accu-Flange Collars are machinable collars similar in many respects to our shaft mounting collars but without predrilled holes, allowing for full customization of the flange by the customer.

They feature a standard keyway and integral clamp that provides a high-strength, non-marring hold. Applications include use in cam, pulley, and component mounting devices.

If needed, users can customize the standard product to unique specifications to meet precise application requirements.

Accu-Flange™ Shaft Mounting Collars

Accu-Flange mounting collars are machinable flange collars that feature a standard keyway with three through holes and three tapped holes and an integral clamp design and relief groove mechanism. They’re also available in metric.

These easy-to-adjust components maintain perpendicularity to <0.001 TIR, allow for the attachment of gears, pulleys, and sprockets without the need for welding, and eliminate the risk of shaft damage. They are suitable for use in a wide range of applications, including in cam, pulley, and component mounting devices.

For users with unique needs, standard Accu-Flange shaft mounting collars accommodate use in custom solutions as the individual parts can be machined to highly specific dimensions upon customer request.
