Typically, the shaft is in two INA Bearing support radial and axial direction, known as the fixed end side of the rolling bearing, which two kinds of radial and axial loads, from the fixed shaft between the bearing housing relative axial displacement effect. Called the free end of the other side, only radial load, axial relative movement can.
With both fixed-end bearings must be fixed to the shaft and bearing housing, more appropriate INA bearings can bear radial load composite bearings, such as deep groove ball bearings, spherical roller bearings and double row angular contact ball bearings or pairing or cone roller bearings. Subjected to pure radial load radial bearing assemblies, such as the inner and outer ring without ribs Cylindrical roller bearings and deep groove ball bearings or via four-point contact ball bearings or bi-directional thrust bearing combination, can be used as a fixed end bearings. At this time, the second bearing provides bidirectional axial location, but the installation of the bearing housing must maintain a certain radial interval. The free end of the bearing due to thermal expansion of the shaft, the length change, the extrusion does not occur within the bearing. Axial displacement can occur in the bearing, the bearing ring may also occur with the bearing.
"Cross-fixed 'refers to a INA Bearing configuration, where each one-way bearing is positioned on the shaft and in the opposite direction. This combination is mainly used for short axis. All at least able to withstand axial load in one direction, the radial bearing are applicable, including deep groove and angular contact ball bearings, tapered roller bearings and cylindrical roller bearings NJ, with angular contact ball bearings or tapered roller bearings in some cases, the pre-load must be applied.
