Description Precision glass filled nylon tracking wheel with sealed bearings for DIY style 2×72 grinders like GIB, EERF, NO WELD etc. Also work well on any professionally manufactured 2×72″ belt grinder. We designed these wheels with weight in mind, they really zip & will give your grinder extra help if you started off with a slightly underpowered motor. Made with the exact same injection molding technology & material as used on modern automotive engine serpentine belt idler wheels for extreme durability & longevity under very harsh conditions. The wheel is 4″ in diameter & crowned to ensure accurate belt tracking. We make our wheels 2-1/4″ wide to accept any commercial 2″ grinding belt. Includes sealed bearings which can easily be replaced when worn. Bore of the bearings is 1/2″ so you can use any 1/2″ diameter bolt as an axle. We use these wheels in our top quality grinders & have tested them extensively.
