extended inner ring

(V) full complements of balls

(N) with snap ring of balls

(NR) with snap ring groove and snap ring

(F) with flanged outer ring

examples of special designs:


LOAD Single row radial ball bearings with ball separated by a cage can support radial loads, axial loads and tilting moments. A full completment V-type ball bearing can support only radial loads and some low axial loads.
SPEED Maximum permissible speeds for ball bearings are mainly related to the bearing design and size, cage type, bearing internal clearance, method and type of lubrication, manufacturing accuracy, sealing methods and loads.
TORQUE AND NOISE LEVEL Single row radial ball bearings are precision components and have low torque and noise levels.
INCLINATION OF INNER/OUTER RINGS Shaft and housing seats with poor accuracy, fitting errors and shaft bending might cause inclination beteween the inner and outer rings although the internal clearance of the bearing will permit this to a certain extent. Generally, the maximum permissible inclination between the inner and outer rings is approximately 1 in 300.

Bearings under load deform elastically at the contact point between the rolling element and bearing ring. This is influenced by the bearing type, size, form and load.

INSTALLATION AND REMOVAL The single row radial ball bearing is a non-separable bearing. Therefore, shaft and housings should be so designed to enable bearing inspection and replacement when necessary.
AXIAL LOCATION Improved axial location is obtained with NR and F type bearings.
