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.
