full complement bearing的意思|示意

'

Full complement bearing is one type of rolling bearing consisting of all the rolling elements provided, with no cage as the maximum capacity of load bearing per contact point. Full complement bearings are used in applications that require high load capacity, such as machine tool spindles, cranes, heavy machinery, and rotating machinery.

Full complement bearings can be divided into two types: cylindrical roller bearings and needle roller bearings. Cylindrical roller bearings are mainly used in heavy-duty machines, and its capacity is much higher than ordinary bearings. Needle roller bearings are mainly suitable for cases where its radial size is small and allows for compact outer diameters.

In addition, full complement bearings have the advantages of high loading capacity, large number of rolling elements, low friction, wear-resistance and being able to bear the axial load in either direction.

When using full complement bearings, one should remember that it has some limitations like not being able to bear radial loading and its inability to be used in high-speed applications. Moreover, regular lubrication should be performed to make sure its full load capacity is reached.
