Create your own working prototype of special-purposed shaft collars and components within hours.
Accepts 3-D printed inserts for unlimited bore possibilities.
Master collars available in three sizes in steel, stainless steel and aluminum.
SPARC™ - the Stafford Prototype and Repair Collar System - enables users to create their own working prototypes of special-purposed shaft collars within a few hours.
Precision machined shaft collar masters are available from stock and accept 3-D printed inserts with bores to fit virtually any type of shaft.
3-D printed inserts in the SPARC™ system can be either user-defined or selected from a library of designs offered free from Stafford.
The inserts are designed to mate securely with the master to create a unified working part and can include holes, bosses, slots, tabs, hubs, pulleys, and other features.
Using the customer’s own 3-D printer, Stafford’s or a third party, the insert is produced in a fraction of the time it would take to machine the part.
Supplied in steel, stainless steel, or aluminum, masters come in three sizes to accommodate shafts from 1/8” to 2-3/4” O.D.

Provides bi-directional axial adjustability along a shaft.
Can be used as a locator or stop
Knurled edges for easy turning
Wrench flat for applying added torque to move heavy parts
Superior axial holding power
The Adjustable Thrust Collar Assembly clamps directly to a shaft and provides infinite controlled movement in either direction. The collar assembly consists of two knurled collars which clamp directly onto a shaft and feature a male-female connecting hub that provides a range of adjustment. Each side includes a wrenching flat to impart added torque.
Providing 3/8" to 3/4” axial adjustability, depending on bore size, it can be used for applications ranging from pre-loading bearings to moving heavy components along a shaft. Since the entire assembly consists of two one-piece collars which clamp directly to a shaft and screw into each other, it provides superior axial holding power.
To make a simple axial adjustment, just clamp one side of the assembly on a shaft, move the other side, then clamp it, and repeat the process infinitely as needed.

Maintains shaft alignment
The 100:1 Phase Adjuster Coupling is a multi-function component with unique capabilities. As a coupling it makes it easy to adjust the phase relationship between two shafts. As a component mount, it makes it easy to adjust the phase relationship between shaft and a mounted component.
Phase adjustment is accomplished when the drive system is stopped. Adjustments are made by hand in either direction by adjusting the knurled outer ring producing infinitely variable relative rotation of the hubs through a 100:1 reduction ratio.
Rotary Encoder Collars add speed sensing capability to shafts. Machined from aluminum, they feature steel targets that can be read from both the face and O. surfaces. Since they are fully split, they can be mounted to shafts without the need to remove other components. Suitable for new and retrofit applications, they are designed to operate in the presence of oils or coolants.
