Multi-purpose greases: Does it always have to be lithium?

To allow engineers and users to plan more securely and with less dependence on lithium, lubricant specialist Rhenus Lub is releasing an innovative multi-purpose grease that is completely free from this ingredient. The new EP multi-purpose grease rhenus CMN 2 is calcium-based, but has an equivalent level of performance and quality to lithium-based greases. This means that users and engineers remain unaffected by the rising price of lithium, without having to compromise on the excellent performance of comparable lithium products.

This was of utmost importance for the development department at Rhenus Lub, as explained by Dr Marco Pfeiffer, Product Manager Lubricating Greases at Rhenus Lub: “With rhenus CMN 2, we have redefined the performance of calcium-based greases — cost planning certainty is of no use to customers if the performance of our alternatives to lithium products falls by the wayside. The only way of guaranteeing success is therefore the perfect combination of performance and cost stability.”

Calcium EP multi-purpose grease rhenus CMN 2 can do anything that a lithium-based product can do. It has good sealing properties and can be used at the same temperature as lithium greases. Thanks to its extreme water resistance and excellent adhesion, rhenus CMN 2 even has advantages over lithium-based greases. This means that the calcium grease can be used in an extensive range of applications in many industries, for example construction and agricultural equipment, industrial forklift trucks, lorries, slewing bearings on cranes, mining, shipping, lubrication of pump and press bearings and other general roller bearing applications. “Thanks to the properties of rhenus CMN 2, which are at least equivalent to those of lithium multi-purpose greases, our customers and users are less dependent on lithium and can already start planning for the future,” says Dr Marco Pfeiffer.
