Lowspeed pins and bushings are a form of journal bearing in which the shaft or shell generally does not make a full rotation. The partial rotation at low speed, before typically reversing direction, does not allow for the formation of a full fluid film and thus metaltometal contact does occur within the bearing. Pins and bushings continually ...
