Technical Topic Lubricating Grease Basi

and mechanical stability. Consistency Under the mechanical stresses of an application, some lubricating oil is “squeezed” out of the grease thickener matrix and delivered to the lubrication points, providing the lubrication, fi lm formation, and wear prevention that is required to ensure optimum equipment performance.

Grease lubrication mechanisms in rolling bearing systems .

Fig. 4 shows an example of the temperature profile of a cylindrical roller bearing running under self-induced temperature [14]. Grease life and relubrication Grease life is defined by the point in time where the grease can no longer lubricate the bearing. This time may be very long and therefore difficult to measure in a bearing test rig.

LGHP 2 - high performance grease - rolman.c

LGHP 2 is a mineral oil based grease, using a modern poly urea (di-urea) thickener and is highly recommended for the lubrication of antifriction bearings. • Excellent performance in a wide temperature range • Excellent water resistance and corrosion resistance • Excellent mechanical stability • High speed grease • Outstanding long life

Storing Grease to Avoid Bleed and Separati

When storing grease and even during use, a certain amount of oil bleed will develop. Although it is common, the rate at which this bleeding occurs can be controlled through proper storage and usage techniques. Before looking at these strategies, it is important to understand the make-up of grease ...

Running temperature and mechanical stability of grease as .

Abstract. Spherical roller bearings in railway car wheels are critical components whose failure may have catastrophic consequences. The present study aims to analyse the mechanical stability of greases and temperature of bearings as indicators for condition-based bearing maintenance.

Mechanical Stability of Lithium Complex Grease Using .

working. Sample 1 begins loss of stability at 200 revs with complete loss of stability at 310 rev; where as, Sample 2 begins loss of stability at 360 revs with complete loss of stability at 460 revs. Here we see a user friendly, simply and yet extremely precise test method for comparatively evaluating the mechanical stability of grease formulas.

Probing the effect of thickener on tribological properties .

Generally, grease lubrication operates under starved condition in the contact area, the film-forming property and thermal stability of the grease are crucial to the lubrication performance especially for the starting-up and running-in stage, which is the major wear-emerging stages.

How Grease Keeps Bearings Running by Boca Bearings .

However, the stiffer the grease, the harder it is to lubricate the bearing surface using channels from a central lubrication system. Plain bearings usually use Grade 0 through 2. Softer grades, 0 and 1, are easier to feed to rows of machine elements, but offer less mechanical stability than Grade 2 grease.

Molykote® G-6000 High Temperature Bearing Grease, High .

Temperature Bearing Grease is a synthetic oil-based grease thickened with polyurea. It can be used at extreme high temperatures, and offers excellent low temperature behavior. Due to the polyurea thickener it is also very stable to mechanical shear. Molykote G-6000 High Temperature Bearing Grease is well suited for applications exposed to ...

On the Assessment of Mechanical Degradation of Grease .

It is hypothesized that the mechanical degradation of grease is akin to the running-in process in a tribo-pair with both transient and steady-state regimes. To validate the hypothesis, a series of mechanical shearing tests are performed on three grades of grease: NLGI 00, NLGI 1, and NLGI 2.5 by employing a rheometer.

high-temperature lubrication points. 4. Excellent Mechanical Stability When grease is fed through narrow tubes or used in bearings, it is exposed to mechanical shear. If the grease has poor mechanical stability, then the grease structure will be destroyed, resulting in softening, oil separation, and tube clogging. Epnoc
