Stafford SPARC collar system accepts 3D printed inserts for special-purposed shaft collars.
Stafford Manufacturing Corp. has introduced SPARC (Stafford Prototype and Repair Collar), a rapid prototype and repair collar system that lets users create their own 3D printed special-purposed shaft collars. The SPARC system features precision machined shaft collar masters that accept 3D printed inserts. The inserts can be either user-defined or selected from a library of designs offered free from Stafford. The printing can be done free by the user or from Stafford for a fee. The inserts are designed to mate securely with the master to create a unified working part. Supplied in steel, stainless steel, or aluminum, masters come in three sizes to accommodate shafts from 1/8 to 3-inch O.D.
