Partial bearings consist of a limited number of contact points between the bearing and the rotating or sliding shaft. Unlike traditional bearings, which encircle the shaft completely, partial bearings might cover only a portion of the shaft’s circumference, or they may consist of discrete elements arranged to provide partial support over a limited section of the moving part. The two primary types of partial bearings are:

Partial-Arc Bearings: These bearings typically feature a bearing surface that covers only a segment of the shaft’s circumference. The arc can vary depending on the design requirements.

Segmented or Point Contact Bearings: These bearings may consist of multiple small bearing segments that are spaced around the shaft, such as needle bearings or ball bearings in selective locations.

The size and positioning of the bearing elements in partial bearings are designed based on the expected load distribution, speed of rotation, and thermal conditions in the system.
