Abstract
A rotor shaft is supported in a housing of a rotor assembly for a laser level. Bearings support the rotor shaft for rotation relative to the housing. An adhesive fixes an outer race of at least one of the bearings in position between the rotor shaft and the housing. The adhesive is a low viscosity, quick setting anaerobic adhesive, which when cured prevents angular drift of the shaft relative to the housing by eliminating the clearance that would have existed between the outer race and the housing.
