The product was designed to increase the weight capacity of the Standard Auto Dolly from 6,000 lbs. to 10,000 lbs. per set of 4 dollies. Remove the original Standard casters and bolt The Heavy-Duty casters on. The difference between these two caster types is their size and construction. The Heavy Duty caster is upgraded with three sets of bearings and has a larger diameter than the standard ones. While one set of bearings is installed on the swivel and provides a higher weight capacity, two others are on the axle and offer the most minimal start-up effort. The larger diameter allows the wheel to handle expansion joints in a more efficient way.
The wheel is made of polyolefin that is resistant to water, grease, gasoline, and other most used chemicals as well as it’s non-conductive and won’t mar the floor. Moreover, thanks to a yoke made of heavily embossed steel and deeply embossed single-ball raceways, the product offers the highest level of durability and strength. This USA-made item is backed by a limited lifetime warranty to ensure peace of mind that it will bring reliable and excellent service for a long period of time.
