Truly a 5 star product with a 3 star description. The product description states that adapters are included to use this wheel on a 1/2" shaft. Not true; only 5/8" and 3/4" shafts can be used for the items supplied. Built in 5/8" bearing comes with an alternate set of 3/4" bearings. To install this on my Coleman washer with a 1/2" axle shaft I had to use copper tubing with a 1/2" ID and 5/8" OD buy pipe into the wheel and marked the spot where both bearings would be worn. I used a pipe cutter to cut it to length and my "fixture" worked great. However the cost of the copper pipe and the hassle of traveling to the hardware store didn't add up to the theoretical convenience of buying online through Revain I have bought 9 of these wheels at various times and they have all served me well, previous uses have used a 5/ 8 inch stock that was installed without an adapter. high.
