There are two bearing lubricants used for the laboratory grade motors: a PTFE based grease and a dry film lubricant. The PTFE based grease has a vapor pressure of 10-12 Torr at 20C and the dry film lubricant has a vapor pressure of 10-14 Torr at 20C. In terms of wear life the PTFE based grease can be expected to last four times long.
