Methods are directed towards dynamically determining refrigerant film thickness at the rolling-element bearing and for dynamically controlling refrigerant film thickness at the rolling-element bearing. Further, an oil free chiller system is configured for dynamically determining refrigerant film thickness at the rolling-element bearing of the oil free chiller system, wherein the oil free chiller system is also configured for dynamically controlling refrigerant film thickness at the rolling-element bearing of the oil free chiller system.

A turntable lubrication device for lubricating sliding mating surfaces of a base plate and an upper plate, the device comprising; —a casing, and—a lubricating grease contained and sealed within the casing, which lubrication device is intended to be manually positioned on the mating surface of the base plate and ruptured under pressure of the upper plate when the upper plate is positioned on top of the base plate, thereby allowing the grease to be distributed between the mating surfaces. The lubrication device is elongated and plastically formable, thus allowing the device to be shaped and curved so that it substantially follows a circumferential shape of the base plate such that the grease is evenly distributed over the sliding mating surfaces.

A chainsaw, a lubrication system for a chainsaw, and a lubricant for a chainsaw are provided. The chainsaw includes a lubrication system and guide bar extending from a housing. The lubrication system includes a reservoir at which a lubricant is contained. The reservoir is releasably attachable to a machine drive device. The machine drive device includes a body at which a pump apparatus is positioned. The machine drive device forms an inlet opening in fluid communication with the reservoir. The machine drive device forms an outlet opening at which a conduit is fluidly coupled to receive the lubricant. The conduit forms a conduit outlet through which the lubricant is provided to the guide bar.

A method of lubricating a fluid production pump may include mixing a polarized lubricant with water to produce a diluted lubricant. The method may additionally include creating a flowpath within the fluid production pump. An initial volume of the diluted lubricant may be circulated within the flowpath to allow the diluted lubricant to react with components of the fluid production pump and form a protective barrier on the components of the fluid production pump. The method may further comprise repeatedly introducing a periodic volume of diluted lubricant into the fluid production pump according to a predefined lubrication schedule.

A scroll compressor includes a first scroll member, a second scroll member, and an aerostatic thrust bearing. The aerostatic thrust bearing forms a layer of gas between the second scroll member and a fixed supporting member to support the second scroll member as the second scroll member rotates and/or orbits. Also disclosed is a method of supporting a rotating/orbiting scroll member in a scroll compressor. The method including supplying pressurized gas to an aerostatic thrust bearing such that a layer of gas is formed between the rotating/orbiting scroll member and a fixed supporting member.
