Judging from the raceway geometry, these bearings can be considered similar to angular contact bearings. They support bidirectional axial loads and low radial clearance; they can then be dismounted, in fact they have an external ring, balls and cage integral and independent from the internal part, which is made up of two half rings specially coupled to the external group and therefore not interchangeable with others, even if of the same series and size. The four-point contact ball bearings have a reduced axial thickness, a high axial load capacity and an inner ring in two halves which facilitates assembly and disassembly operations. The cage can be in brass for working conditions from -30 ° C to + 150 ° C or in polyamide loaded with glass fibre for temperatures up to a maximum of + 120 ° C.
