Speed-up split spool for quick installation or replacement. Large diameter spools are often used for accumulation zones. Fits together tightly, no need for adhesives. Fits 1" or 25mm shafts. 1.6" wide, 1.67" diameter.

The bore on these spools didnt form perfectly round after leaving the mold, so they fit tighter on the shaft. Normally the spool should be slightly loose and drives using friction supplied by a tight belt.
