1.Clarify the model of Sendzimir bearing

The model of Sendzimir bearing indicates the basic size of the bearing, original clearance, cage type, sealing form, lubrication requirements, etc. Therefore, it is necessary to clarify whether the bearing model is correct before starting the installation

2. Positioning of Sendzimir bearings

In order to run smoothly, a shaft generally has at least two points for axial and radial support, and each point has at least one or more bearings. Under normal condition, one bearing plays a role in positioning, while the other bearing does not. Positioning bearings provide radial support and axial guidance. Therefore, the positioning bearing must be fixed on the shaft and the bearing housing at the same time. Deep groove ball bearings, spherical roller bearings, double row angular contact ball bearings, paired single row angular contact ball bearings can all be used as positioning bearings. Paired tapered roller bearings can also be used. Cylindrical roller bearings without flanges can also be used as locating bearings when matched with thrust bearings with radial clearance.

Non-locating bearings only provide radial support, which must be movable in the axial direction. The axial movement can be generated by the bearing itself (for example, cylindrical roller bearings), or it can be the relative movement between the inner or outer ring of the bearing and its support.
