Bearing arrangements

locating and non-locating bearing arrangements

The Locating and non-locating bearing arrangements is the most common.

The locating bearing at one end of the shaft provides radial support and at the same time locates the shaft axially in both directions. It must, therefore, be fixed in position both on the shaft and in the housing. Apply to the fixed end bearing types are: e.g. deep groove ball bearings, self-aligning ball bearings,spherical roller bearings,double row or paired single row angular contact ball bearings, matched tapered roller bearings and Cylindrical roller bearing(NJ+HJ and NUP design)

Locating bearings provide radial support and, if necessary, can withstand thermal expansion of the shaft relative to the axial displacement of the bearing. For floating-side bearing, axial displacement occurs between one of the bearing ring and its mating surface, usually between the outer ring and the housing bore, the bearing type is suitable for locating include: deep groove ball bearings, self-aligning ball bearings spherical roller bearing

Adjusted bearing arrangements

In adjusted bearing arrangements the shaft is axially located in one direction by the one bearing and in the opposite direction by the other bearing. This type of arrangement is referred to as "cross located" and is generally used for short shafts.Any can withstand axial load in at least one direction radial ball bearings and roller bearings are suitable for cross-locating bearing configurations, including: deep groove ball bearings, angular contact ball bearings, tapered roller bearings.
