NSK now offers the world’s first lubricant grease for bearings derived from 100% food grade ingredients

Typical applications range from food machinery such as shakers, fillers, centrifugal separators, bottling machines and conveyors, through to pharmaceutical, cosmetics and medical process devices, including pumps. Importantly, the environmentally friendly grease conforms to the highest international standards for safety regarding products that may come into accidental contact with food.

The new NSK eco-friendly grease, which is petroleum-free, exceeds the standards of lubricants currently used widely in such applications. These are generally based on rapeseed oil and other vegetable oils that contain many non-food ingredients. Such greases can also have performance limitations, with lower oxidative stability, resulting in lubricity and durability issues.

In contrast, NSK’s grease is made entirely from food-based ingredients including the base oil, thickening agent and additives. For instance, food-grade vegetable oil is used for its excellent heat tolerance as a base oil, while the thickening agent contains food additives with a fine 3D network for good base oil retention.

The lubricant is also formulated with food additives that further enhance the durability of the base oil, delivering a grease that offers enhanced oxidative stability and one-third lower friction loss (torque) than existing comparable products. Further advantages are less leakage and longer service live, even where there is exposure to water.

From an environmental perspective, the grease is naturally biodegradable and produces no toxic waste, making it both non-polluting and fully sustainable.
