The last 3 photos show the advantages of this wheel mount over the traditional installation. I install these wheels in my lane of belt sanders. The advantages of using this wheel in comparison to a standard drive wheel mount. The ability to obtain a higher range of belt surface speed.
Taper mount is a lot more secure than standard key and set screw system. Solid drive wheel with its big mass often gets loose and shifts sideways. Tapered wheel bore allows the use of various motors (including those with metric shafts), because taper bushings are popular and come in many bore sizes. Lighter wheel mass means less starting power that often causes circuit break fuses to blow. Also a better machine balance.Probably the most advantage comes from the fact that this wheel is protruding 3-1/2 from the face of the motor, still being fully inserted on the motor shaft. This is something that many builders have had the biggest problem while assembling their machines, virtually being unable to make such assembly when using standard drive wheel. Less parts or components to align. Improved sander balance, stability and better belt tracking. Greater adjustment, accuracy and alignment. Speed calculation : If your 7 Drive Wheel rotates at 3450 RPMs, then the belt surface speed is 6322 SFPM (Surface Feet Per Minute).
