Frequently Asked Questions

Rolling motion can be used to carry and transmit load while facilitating movement with very low friction and low wear rates , even in the absence of lubrication.

The best know example where this is used is the wheel , invented by Mesopotamians in ca.3500BC.

Lubrication of wheel-road (or later wheel-rail) contact is difficult, but even in the absence of lubrication wear rates are much lower than those of , for example, sledges or sliding shoes.

The rolling bearing is based on this principle, although the configurationis more complex since , for carrying a single load , several rolling elements are used , which have a double contact(with the inner-ring and the outer-ring).Unfortunately, even in the apparently rolling contacts , slip occurs.

This is partly due to the elastic deformation of the bodies in contact, which flattens the contactsto some extent , and partly due to the kinematics in the bearings.

The first effect is usually very small (and can be decreased by using materials with a high lastic modulus).

The second effect is more severe.

The first effect is dominant in the contacts on tapered and cylindricalroller bearing raceways, which can run at very low friction levels(note that this does not applyto the contacts on the flanges in these bearings).

For other bearing types, sliding profilesin the contacts between rolling element and rings typically show just one or two points of purerolling.

Positive slip occurs between these points and negative slip outside these points.

Grease is defined as ‘a solid to semi-fluid product or dispersion of a thickening agent in a liquid lubricant.

Other ingredients imparting special properties may also be included’ The base oil is kept inside the thickener structure by a combination of Van der Waals and capillary forces.

Interactions between thickener molecules are dipole-dipole including hydrogen bonding or ionoic and Van der Waals forces.

The effectiveness of these forces depends on how these fibres contact each other.

The thickener fibres vary in length from about 1-100 microns and have a length diameter ratio of 10-100,where this ratio has been correlated with the consistency of the grease for a given concentration of thickerer.

Sometimes grease is called a thickened oil (tather than a thick oil).

Generally, a lubricating grease shows visco-elastic semi-plastic flow behaviour giving it a consistency such that it does not easily leak out of the bearing.

Automatic Lubrication System referred to a system that delivers controlled amounts of lubricant to multiple locations on a machine while the machine is operating. The system can be classified into two different categories that is Oil systems and Grease systems.


Automatic lubrication systems are key aspects in maintenance & reliability programs. They supply lube points with metered amounts of grease or oil from a central location. The pump supplies the system with the chosen lubricant and is fed from a reservoir that is easily accessible. Depending on the application, the reservoir ranges in sizes and can be as small as 1 liters all the way up to an intermediate bulk container or even a bulk tank. The options are almost limitless and are application specific. These systems have the option to be monitored remotely with feedback and can be tied directly into your plant’s PLC. So whether you’re running an excavator, driving a ready-mix truck, operating a crusher, or making steel, you can rest assured that your assets are being properly lubricated at all times. 

Single point lubrication is normally usd when only a few lubrication points are located on a machine and these are far away from each other.

In this case a centralized lubrication system is not economical.

Another reason to use sinle point lubrication is when several lubricants are used, In this case the lubricant cannot be supplied from a common reservoir.

If only such single points need to be lubricated, either manual lubricators or ‘automatic lubricators’ are used.

Manual lubrication is typically done with grease guns. which are manual pumps with an extension pipe with a hydraulic gripping nozzle.

An alternative to manual lubrication are the single-point ( or multi-point)automatic lubricators.

An example are the so-called “system 24′ lubricators, which are automatic gas-driven single-point lubricators.

A time-setting slot enables the adjustment of lubricant flow.

The pressure to a piston is provided by an electromechanidally driven.

The piston pumps the grease towards the fitting, mounted on, for example, a bearing housing.
