It is important to note that the elements responsible for the entire shaft locking process, normally used for protection during the entire transport process, in the case of motors having roller bearings or angular contact, must be used for any locomotion of the engine , even if this factor requires the uncoupling of the driven machine. Therefore, all motors with these characteristics, regardless of the bearing category you get, should always keep your rotor locked at the time of transport. Vertical motors containing oil lubricated bearings must be transported in an upright position.
If it is necessary to carry the motor in a horizontal position, the axle locking device must be used on the front and rear sides of the motor. When dealing with the handling of any type of electric motor, any movement that is necessary, must be done in a subtle way, avoiding in this way, any type of impact, or otherwise the bearings found in them, may serious damage, as well as if the eye bolts are subjected to excessive force and can result in eyebolts breaking. In electric motors there are numerous devices whose main function is to ensure its efficient operation. https://www.mrosupply.com/hydraulics-and-pneumatics/hose-reels/2793428_ca33128-l_reelcraft/
