Shaft-Hub Connections are suitable for friction locked fastening of all kinds of hubs on shafts and axles. They can be applied wherever conventional shrink fits, wedge, keyed andpolygonal connections, splined shafts, etc. have been used so far. Cog wheels and sprockets, levers, lifters, cams, pulleys and brake discs, flywheels, couplings, slip-on gears, flanges, sheaves and impellers are thus fastened precisely and securely.
