KOYO bearings are widely used in aviation technology; computer components; motors; high-speed trains; MRT trains; industrial machinery; CNC lathes; high-precision processing machines; automotive industry; locomotive industry;
Outer spherical bearings are primarily used to accept radial and axial combined loads with radial loads; it is generally not advisable to accept axial loads alone; such bearings can be separated from the inner ring of the device (with full set of rollers and retainers) and圈. This kind of bearing does not allow the shaft to be skewed relative to the outer casing; additional axial forces will occur under radial load commissioning.
The outer spherical bearing is preferably applied to the occasions where the required equipment and components are simple; for example, for home machinery; transportation system or construction machinery. An outer spherical ball bearing unit consists of a double-sided sealed spherical outer ring deep groove ball bearing and a Gray cast iron or stamped steel bearing housing.
Most of the outer spherical ball bearings are fixed bearings; therefore, they are uniquely suitable for supporting short shafts; and they are suitable for applications where only a small thermal expansion occurs. The small thermal expansion of the shaft can be compensated by the axial clearance of the bearing.
Application of outer spherical bearings:
The outer spherical ball bearing can compensate for the static error of 5 degrees against the center line. The requirement for the smoothing of the bearing from the head can not exceed 2. 5 degrees; otherwise the smooth hole on the outer ring will be blocked.
Type of outer spherical bearing:
Usually the outer spherical bearing types are: UC type; UK type; NA type; SB type; SU type; ER type; RB type.
