good morning WW
I thought that some of you might be interested in seeing some of the details on how large industrial BS tires are changed. If you have ever looked at some of the on line auctions of 36" bandsaws, you may have seen photos of the wheels. Many modern 36" bandsaws used "carter high speed wheels" or some close clone of them. The carter wheel has a few nice features that have made them pretty much the industry standard. They are capable of 180 mph speeds without flying apart ( older cast iron wheels had a limit to their speed because of this potential problem ), and they are easily "re-tired" as opposed to the glue on or vulcanized rubber tires. although my saw was in very good shape, the tires were somewhat worn and so I decided to replace them. The photos below show some of that process.
the carter wheel is a split rim that unbolts and the tire slips off. the new one slips on and is held in place by the little "nubs" inside of the tire. Those nubs lodge themselves in the indentations of the rim and prevent the tire from spinning on the rim. The tire itself is a combination of steel and rubber vulcanized, ground to shape and balanced.
I thought you might also like to see the size of the " Hub and brake" setup on this particualr saw. The motor shaft you see in the photo is 1 7/8" diameter ( the saw has a 30 hp motor frame size that is direct drive to the wheel... no belts )
enjoy
