Special wheel bearing (innovation bearing) 12x31x8 suitable for the original front Sachs sheet metal hubs of wire spoke rims with bearing shells, which have an outer diameter of 31 mm.
The ball bearings are fitted with a dust cover on both sides. They replace the originally installed individual cone bearings, which consist of bearing balls, cone and bearing shell. With the new complete ball bearings, laborious installation is no longer necessary for every overhaul on your moped, moped and small motorcycle.
For installation, an intermediate sleeve must be created between the wheel bearings, which varies in length depending on the wheel hub type so that the bearing is not axially loaded.
