Rulmenţii axiali-radiali cu bile cu dublu efect sunt lagăre de precizie demontabile cu toleranţe reduse în clasa SP. Ei se compun din inele interioare şi exterioare masive, inele de distanţare, precum şi din colivii masive cu bile din alamă. Componentele rulmenţilor sunt imperecheate şi se pot monta dezmembrate. Nu e permisă interschimbarea componentelor mai multor rulmenţi între ele.

Double direction axial angular contact ball bearings are non self-retaining precision bearings with restricted tolerances to class SP. They comprise solid shaft locating washers, spacer rings, housing locating washers and ball and cage assemblies with solid brass cages. The parts of the bearings are matched to each other and can be fitted independently of each other; they must not be interchanged with those of bearings of the same size.
