The invention discloses a radial loading device of a multifunctional bearing testing
machine. The radial loading device comprises a bottom plate, a guide rail, a radial loading base, an axial guide base, a loading cylinder installation base, an installation base location pin, an installation base connection bolt, an installation base T-shaped locking bolt, an axial loading cylinder, a front guideseat, a coupler, a
pressure sensor, a rotation stop pin, a force applying shaft, a bearing test installation tool, a tool connection bolt, a sensor installation assembling body and a front guide basefixed T-shaped bolt. The present invention relates to a combined type rolling bearing
life test machine, concretely a radial loading device of a multifunctional bearing testing
machine cooperative with the axial loading tool and an inclined loading tool to complete applying of three different loads for the test bearing, and the radial loading device of the multifunctional bearing testing machine can apply radial loads in two
modes of pulling or pressing for the test bearing, and is convenient and rapid in loading, simple to operate, convenient to maintain and convenient to dismount and
mount.
