Correct Lubrication

Lubrication of bearings is normally done with mineral grease. When operating temperatures are high, from 120ºC to 150ºC or the speeds of rotation are above 1,500 RPM, we use mineral oil for lubrication. These oils must have the lubricating characteristics appropriate to the working conditions.

On low-power electric motors, initial lubrication is planned to ensure a large number of hours of operation. Sometimes the grease dodge 011297 reserve is sufficient for the entire life of the machine. On larger electric motors there is a need for external lubrication. The frequency of lubrication will depend on the design of the bearings and the characteristics of the lubricants used.

It is important to know that at a temperature of 40 ° C, the life of a continuously running ball bearing can be from 3 to 4 years or more. However, for every 10 ° C increase in working temperature the service life decreases by an average of 50%. Correct lubrication of the bearings, besides allowing an improvement of performance, avoids the increase of the temperature that damages the useful life of these equipments.
