The attachment is easy to install and does not require the use of other devices to fixed it.
When used on an optical shaft, the bearing can be fixed in any position on the shaft.
When used on the step shaft, the tight sleeve, in conjunction with the L-shaped spacer ring, allows the bearing to be more precisely fixed at a given position on the shaft, thus facilitating the mounting and dismounting of the bearing.
