6" x 1-1/4" No-Matic Thermoplastic Rubber (TPR) Wheel w/ Ball Bearings - 150 Lbs Capacity

Recommended - 6" x 1-1/4" No-Matic Thermoplastic Rubber (TPR) Wheel Quality: Fit and Finish are first quality Density: Tubeless. Tire is firm, does not depress with thumb pressure. Floor Marking: Tire does not mark floor when under load and slid sideways with some effort on a smooth concrete floor. Other Observations: The optional 5/16 inch Delrin bushing is advertised as shortening the hub length compared to the metal ball bearings, however, I'm finding the bushing increases the hub length. My comments to Mapp were well received. Mapp personnel advised they forwarded my findings about the 5/16 in. Delrin bushing to their technical and engineering department. This is what good companies do.
