Ball Bearings RLS Series

Ball Bearings RLS Series
For the same type of RLS series bearing, the smaller the size, the higher the allowable speed.When choosing bearings, it should be noted that the actual speed should be lower than the limit speed.

Bearing travel and axial displacement: normally, a shaft is supported by two bearings at a certain distance.In order to adapt to the influence of different degrees of thermal expansion of the shaft and housing, one bearing should be fixed in the axial direction when installed, and another bearing should be allowed to move on the shaft (that is, to move the bearing), to prevent the dead phenomenon caused by the extension or contraction of the shaft.Cylindrical roller bearings with inner or outer rings without baffles and needle bearings are usually chosen as floating supports.At this point, the inner ring and the shaft, the outer ring and the housing hole can be used for tight coordination.When non-separable bearing is used as swimming support, such as deep groove ball bearing and centering roller bearing, outer ring and outer hole must be allowed in the installation, or inner ring and shaft should adopt loose fitting, so that axial direction can be free swimming.

Tapered roller bearings, centering roller bearings and deep groove ball bearings are basically of the positioning type, when used as non-positioning, loose fit installation is adopted.All thrust roller bearings and RLS series are positioning bearings.

Convenience for bearing installation and disassembly:

when choosing the bearing type, consideration must be given to the convenience of bearing installation and disassembly, especially for the installation and disassembly of large and very large bearings.Generally, angular contact ball bearings, tapered roller bearings, cylindrical roller bearings and needle bearings with detachable outer rings are more convenient to be installed and disassembled, and their inner and outer rings can be respectively installed on the shaft or inside the shell bore.In addition, centering roller bearings, double row cylindrical roller bearings and centering ball bearings with tapered bore and tightener sleeves are easier to install and disassemble.
