Replacement of bearings
Both the bearings that have been greased for all their service life and those that need to be greased regularly, as well as hermetic
parts that are subjected to wear and tear (seals and joints, etc.), where applicable, must be replaced after 20,000 operating
hours.
Bearings of the same type as the originals must be installed. Standard bearings for each motor type may be consulted at Table
The procedure for replacing bearings must be carried out as follows:
1.
Disassemble the motor from its location and place it in a safe and clean place.
2.
Remove the accessories from the motor very carefully so as not to damage them and then remove the terminal box and
fan (onlyy in the case that the MAC QM motor has been supplied with tehm). See following sections for more details.
3.
Loosen the gland cable outlet.
4.
Unscrew the motor seals and covers and remove them.
