Abstract: A lubricant pump (1) has a reservoir unit (100) and a pump unit (200). The reservoir unit (100) has a reservoir housing (101). The pump unit (200) has a pump housing (201). The pump unit (200) and the reservoir unit (100) are separably connected. When the housings (101; 201) are connected, the openings (108; 208) are fluid-connected to one another such that lubricant can flow out of the reservoir unit (100) into the pump unit (200). First and second plates (210; 212; 810; 910) are movable such that the opening (108; 208) of the pump unit can be closed and opened. Alternatively or in addition, first and second plates (110; 112; 810; 910) are movable such that the opening (108; 208) of the reservoir unit can be closed and opened.

Abstract: A bearing assembly includes an inner ring and an outer ring that define a bearing interior between them and either the inner ring or the outer ring is fixed. When the inner ring is fixed, the inner ring includes at least one substantially radial through opening and when the outer ring is fixed, the outer ring includes at least one substantially axial and/or radial through opening, or at least one substantially axial and/or radial through opening is provided on a ring fixedly connected to the outer ring. The through opening is disposed between a 9 o'clock position and a 3 o'clock position on the inner ring when the inner ring is fixed or on the outer ring when the outer ring is fixed.

Abstract: A lubricating system for a bearing includes a lubricant supplying system having a first pumping device configured to introduce a first quantity of lubricant into the bearing, a lubricant disposal system including a second pumping device configured to remove a second quantity of lubricant from the bearing, and a controlling device configured to activate the first pumping device and the second pumping device interdependently with each other.
