Revolutions

The   maximum permissible number of revolutions of a ball bearing is mainly related   to several aspects: the design and size of the bearing, the type of cage, the   bearing clearance, the method and type of lubrication, the machining   accuracy, the type of dust cap or seal and the load.

Torque   and noise levels

The   higher the accuracy of single row radial ball bearings, the lower their   torque and noise.

Tilting   of inner and outer rings

Poor   accuracy of shafts and housings, faulty mounting and bending of shafts may   cause tilting of the inner and outer rings, although such tilting is   permissible within the range of the clearance.

Normally,   the maximum permissible tilting of the inner and outer rings is about 1/300.

Toughness

Bearings   are subject to elastic deformation under load where the rolling elements and   rings come into contact.

The   degree of elastic deformation is influenced by the bearing type, size and   load.

Mounting   and dismounting

Single   row radial ball bearings are non-separating bearings. Therefore, in order to   facilitate the inspection and replacement of thousands of bearings, it is   necessary to make the necessary design for the shaft and the bearing housing   as well.

Axial   orientation

Bearings   with stop ring type and with flange type are favourable for axial locating.
