Considerations for lubrication frequency and quantity for electric motors (and generators) include the following:
- Is the lubricant grease or oil?
- Is the bearing type sleeve, ball or roller?
- If it is a ball bearing, is the enclosure open, shielded or sealed?
In this article we will address the above by breaking them down into the following categories:
- Grease lubrication frequency and quantity for ball and roller (rolling element) bearings.
- Oil lubrication frequency and level (relates to quantity) for ball and roller bearings.
- Oil lubrication frequency and level (relates to quantity) for sleeve bearings.
