4″ Diameter Crowned Tracking Wheel

4″ diameter crowned aluminum tracking wheel commonly used on 2″x72″ belt grinders. Lightening cuts are machined into the front and back of the wheel to make it the lightest aluminum 4″ tracking wheel on the market. The wheels are crowned to provide stable belt tracking. A steel spacer is installed between the bearings to prevent over tightening. One wheel with bearings and spacer installed included.
