Single-row self-aligning roller bearing, with single-row self-aligning roller, mainly bears radial load, but also can bear axial load in any direction. It has high radial load capacity and is applicable to work under heavy load or vibration load. Its centering performance is good and can compensate for coaxiality error. The common single-row self-aligning roller bearing cages are mainly solid brass cages, especially the medium and large single-row self-aligning roller bearing cages are only solid brass cages. For this reason, the existing design has been improved and the stamping steel cage has been added.
