NBI single row deep groove ball bearings with fi- lling slots are non-separable bearings. They consist of an inner and outer ring equipped with one filling slot each, to enable incorporating more and larger balls than in single row deep gro ove ball bearings Thank to the designing, single row with filling slots bearings allow greater radial load, thereby having more radial load capacity. On the con- trary, the axial load that these bearings can car is affected, as the speeds that they can operate They are less than the speeds that the single row deep groove ball bearings can support. Their main dimensions are standardized in iso 15:1998

NBI cam followers have an internal design very similar to that of a needle or cylindrical roller bearing. They are characterized by a thick walled outer ring that enables them to accommodate shock loads while reducing distortion and bending stresses. The outside running surface is crowned as standard. However, cam followers with cylindrical (flat running surfaces are available for certain appli cations, Instead of an inner ring, cam followers have a solid stud(pin) that is threaded so that the cam follower can be quickly and easily attached to appropriate machine components by means of a hexagonal nut. Axial guidance for the outer ring is provided by an integral flange at the head of the stud and a lange ring pressed onto the stud, or by the roller complement. Cam followers are pre-greased ready-to-mount units that are suitable for all types of cam drives,tracks and conveyor systems. NBI cam followers are available in three different designs: · KR design · NUKR design · PWKR design All three designs of cam followers have the same main dimensions The differences are in their in- ternal design, which make them suitable for va rious operating conditions. All designs are available with a concentric seat or an eccentric collar, which is shrunk onto the stud enables less stringent manufacturing lerances to be specified for associated components. The ues for the adjustable eccentricity are listed in the product tables.
