  Single column spherical roller bearings

Single row bearing. The rolling element is a single row bearing. This type of bearing is simple in design and non separable. It is suitable for high speed, even very high speed. It is very durable in operation and almost requires no maintenance. For example, single row angular contact ball bearings can only bear axial load in one direction. When bearing pure radial load, this kind of bearing must be installed and used in pairs because the rolling element load action line and the radial load action line are not in the same radial plane and generate internal axial force components.
20312MB Single row bearing, a kind of rolling bearing, with 1 row of rolling element. It is a precise mechanical element that changes the sliding friction between the running shaft and the shaft seat into rolling friction, thereby reducing the friction lo
