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 shock absorber arrangement for a vehicle suspension contains a shock absorber having a damper cap and a piston rod, and a supplementary spring which is arranged on the piston rod opposite the shock absorber and has an outer surface facing the damper cap and an inner surface facing the piston rod, and is configured for damping the movement of the shock absorber in the direction of the piston rod on contact with the damper cap. The outer surface and/or the inner surface is at least partially coated with a lubricant.

A hose lubricating tool for power line hoses. A backboard has a support plate mounted on the front surface. The backboard has a lip portion below the support plate integral with the bottom half. A hinge is mounted to the front surface and attached thereto is a finger base, the finger base mounted to the hinge on the front surface. An indentation is defined within the finger base underneath the front edge. A finger portion is mounted to the finger base, the finger portion extending out over a finger front edge of the finger base to define a finger tip, the finger tip and finger portion sized to be received within a groove of a power line hose. Upon the power line hose being forced along the finger tip, the finger base is urged downward to engage the trigger and release the lubricant.

A high viscosity lubricant and dispenser for use in machine work. In one example, the lubricant includes avocado oil and has a viscosity that allows it to be dispensed from a twist-up type, or other suitable dispenser as a paste, gel, or semi-solid. In another aspect, the lubricant includes wax to increase viscosity, the wax may be of any suitable type such as, for example, soy wax.

A bicycle chain lubricant that may be applied as a coating on a bicycle chain is a crystalline solid at ambient temperatures, yet when the chain is in motion the forces around internal components locally transforms the coating to a lubricous fluid. This increases chain efficiency in the drive train and reduces ware by limiting water and dirt access to chain internal components.

The present invention relates to methods of forming a film between two surfaces, in which the film includes diamond-like carbon. Also provided herein are uses of such films, such in sliding contacts and in metal coatings.

The present invention provides a lubrication device for coating a lubricant onto the outer circumferential surface of a bearing. A lubrication device comprises a housing and a lubrication member that is accommodated within the housing. A bearing crosses and passes through the lubrication member so that an outer circumferential surface of the bearing comes into contact with an inner surface of the lubrication member, and due to this configuration, it becomes possible for the lubricant to be coated onto the outer circumferential surface of the bearing.
