4″ Diameter Crowned Drive Wheel with 5/8″ bore

4″diameter crowned drive wheel for 2″x72″ belt grinders. Lightening cuts are machined into the front and back of the wheel to make it the lightest aluminum 4″ drive wheel on the market. Benefits of lightening cuts to reduce weight equals less rotational mass for faster start ups and decreased loss of power giving you more power to apply for grinding. The wheels are crowned to provide stable belt tracking. A 1725 RPM motor will run at approximately 1800 SFM and a 3450 RPM motor will run approximately 3600 SFM.
