• 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.
