The four key things to remember when applying lubricants in a factory

Lubrication is vital to machine longevity, but it is often carried out without proper understanding of its correct application.

“The four Rs provide a useful point of reference for any application, by breaking down lubrication into four key areas for maintenance managers to consider,” says Graham Wignall. They refer to: the right amount of the right lubricant, in the right place and at the right time.

The right amount

Over-lubricating a bearing can be just as damaging as under-lubricating one. “Excessive quantities of lubricant could damage the surface area of a bearing, leading to cracks and the ingress of dirt,” says Wignall. “It could also cause the bearing to overheat, which will lead to lubricant failure.”

The right lubricant

Many maintenance managers rely on the OEM’s recommendation when choosing a lubricant. “This may be counter-productive,” warns Wignall. “The OEM won’t have a full understanding of the machinery’s working environment, and may also be biased towards a particular brand.”

The right place

Storing a lubricant correctly has a direct impact on its performance and efficacy. “Lubricants should be stored in sealed containers that prevent the ingress of dust, dirt or moisture,” Wignall advises. “Also ensure that lubricants are stored at the correct temperature, as stipulated by the manufacturer.”

The right time

The frequency of application is often recommended by the OEM, but this is usually based on a general set of rules and assumptions regarding the machine’s operating parameters. “Use this as a guideline, rather than a steadfast rule,” says Wignall. “Consider your machine’s working environments and apply these to any lubricating schedule. For example, higher levels of temperature or pressure, or prolonged periods of operation, will require the frequency of application to increase.”
