Solution Series, SPARC Master Collars

Stafford MFG Solution Series master collars are used or securing components onto a shaft. They come with a single-piece split design, allowing them to be easily installed and removed without disassembling the entire shaft or components. These precision-machined master collars are designed to mate with 3-D printed inserts (with bores) to fit any type of shaft with ease. They are available in stainless steel, aluminium & steel material variants and can accommodate shaft sizes ranging from 1/8 to 2-3/4 inches (O.D).
