BEARING LUBRICATING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a bearing lubricating device having inexpensive construction for reliably discharging the waste of lubricating oil supplied to a bearing while properly adjusting the amount of lubricating oil in the bearing.

SOLUTION: An outer ring 5 of the rolling bearing 1 has a plurality of suction holes 6 formed opening in a guide face 5a and passing therethrough in the radial direction of a cage 4. A vinyl tube 14 and a suction pump 12 are connected to the suction holes 6 via a through-hole 9a of a housing 9 so that lubricating oil between the guide face and the cage 4 can be sucked from the suction holes 6.
