Use the following formula to calculate the amount of lubricant for the bearing
according to its outside diameter and its height:
where:
G
p
= amount of lubricant [ gr ]
D = Outside diameter of the bearing [mm]
B = Bearing height [mm]
Nevertheless, it is recommended to refer to the bearing manufacturer’s catalog.
Replacement of the bearings:
The bearings must be replaced before 20,000 hours of operation. To replace them,
follow the instructions described in the next section.
Note that the type of bearing is shown in the section: Bearing characteristics in
chapter 3.
Always use the same lubricant for the bearings or one with equivalent specifications.
Do not add too much lubricant so as not to generate high temperatures and contaminate
the motor.
