LOVATO Electric S.p.A.
Sector: Production of electrical components for industrial applications
“It is easy to find lubricating oils and greases on the market through a search online but it is more difficult to find specific solutions for our application needs. We have reduced mechanical wear by 30 per cent and doubled the number of effective manoeuvres with just one grease change.”

LOVATO Electric designs low-voltage electrical components for industrial applications. The company manufactures and sells over 18,000 products including switches, contactors, pushbuttons and protective relays. It has 14 foreign offices and a network of 90 importers for business in over 100 countries around the world.
The company needed to reduce mechanical wear on the electrical contactors it produced, which was causing components to deteriorate rapidly. Specifically, the high sliding speed combined with the elevated operating pressures prevented the formation of a fluid and homogenous lubricating film between the steel shaft and the bronze support sleeve (the drive components), which were consequently almost always uncovered and in direct contact.
To improve the quality of the product, we started an internal testing campaign. The previous lubricating solution in use, a Teflon silicone grease, did not ensure optimal component life due to the inherent properties of the lubricant (weak resistance to high surface pressures, conditions typical of metal-to-metal couplings). We thus identified the new Maconpaste HP lubricating grease as the ideal product for ensuring a good protective film between the two metal components.
At the end of our investigation, we verified that the use of the new Maconpaste HP lubricant made possible:
