  Hydraulic pump bearing

Bearing without inner ring or needle roller and cage assembly can be selected according to different applications. At this time, the journal surface and housing hole surface matched with the bearing are directly used as the inner and outer rolling surfaces of the bearing. To ensure the same load capacity and running performance as the bearing with ring, the hardness, machining accuracy and surface quality of the raceway surface of the shaft or housing hole should be similar to the raceway of the bearing ring. This type of bearing can only bear radial load.
7311B It has compact structure and small volume, high rotation accuracy, and can withstand high radial load and certain axial load at the same time.
