The Italian scooter racing scene, often at the forefront of scooter racings technological innovation, is not content with the current standards of crankshaft bearings available for their racing scooters. The almost doubling of the amount of engine revs available from modern race motors, as opposed to standard set ups, puts existing bearings under great strain.
The MALOSSI flywheel side crankshaft bearings are delivered as pairs, especially for race use. The bearing cage is constructed using fibre-reinforced poly-amid 66 and is ball bearing based with a high load capacity.
The TB-P6 bearing is a C3 rated ball bearing, has a bearing cage made of phenolic resin with material based reinforcement and stands out with its extremely precise dimensions and manufacturing tolerances. It is ideally suited for use with high-revving motor set ups.
The single row, angularly arranged ball bearing units are designed to be able to deal with both radial and axial forces. They are available with a bronze alloy bearing cage or as a version without a cage, that contains 11 ball bearings. It is no easy job to install this bearing type correctly and we recommend the use of the DRT mounting chuck for best results.
The SKF TN9 are the bearings required for use with FALC crankshaft assemblies. One of these items though can also be used on the flywheel side of non FALC crankshafts...
