A mobile lubrication pump has a motor for driving the pump for producing a pump pressure, a pressure monitor for measuring the pump pressure, a motor controller for regulating the operation of the motor, and a data processing unit (DPU) for communicating with the motor controller, and for receiving: 1) input from the pressure monitor, and 2) user input related to pump capacity and/or lubrication target. The data processing unit is configured to determine and communicate a motor speed and/or motor torque to the motor controller based on the received input 1) and 2).

A method for lubricating a sealed bearing providing a first ring and a second ring capable of rotating concentrically relative to one another, and seals delimiting together with the first and second rings a sealed chamber. The method includes a removing a first predetermined quantity of lubricant from the sealed chamber until the pressure in the sealed chamber reaches a first pressure value, and then injecting a second predetermined quantity of lubricant in the sealed chamber until the pressure in the sealed chamber reaches a second pressure value, the first pressure value and the second pressure value being determined so that the pressure inside the sealed chamber remains within a predetermined interval, the boundaries of the interval being determined according to characteristics of the seals so that the sealed chamber remains waterproof to the lubricant when lubricant is removed from or injected in the sealed chamber.

Provided is a machine tool system that can supply an appropriate amount of lubricating oil to a machine tool according to the operation thereof. The machine tool system comprises: a lubricating oil supply unit that supplies a lubricating oil to a feed shaft of a machine tool; a code analysis unit that analyzes a machining program and determines whether a specific reciprocating operation is to be carried out at the feed shaft; and a control unit which, if it has been determined that the specific reciprocating operation is to be carried out, changes the supply of the lubricating oil via the lubricating oil supply unit to an exclusive pattern when the machine tool carries out the specific reciprocating operation.

A lubricating system has a pump to force a viscous lubricant from a supply of lubricant to a lubricator at which the lubricant is to be dispensed onto a cable, wire, or the like that is being pulled through a conduit. A sensor, associated with a spool from which the cable is being dispensed, is be used to automatically control the amount of lubricant that is to be dispensed onto the cable. A second described system comprises a custom bucket or bucket insert which allow a cable to pass through the bucket whereupon lubricant will be automatically applied to the cable and the container includes a profiled base to ensure proper passage of the cable through the lubricant and ensure the maximum usage of any lubricant.
