Divinol Fett L 800 – Specialized Grease for Rotary Tables and Machine Tool Guides
Divinol Fett L 800 is a specialized lithium soap-based grease designed for the lubrication of linear guides and rotary table bearings in selected machine tools. Thanks to the high viscosity of the base oil, it helps reduce stick-slip, i.e., uneven movement resulting from the alternating sticking and sliding of mating components.
The product has a very fluid consistency and is classified as NLGI 000. Thanks to this, it flows well to the lubrication point and, according to the manufacturer, has better return flow properties than comparable NLGI 00 class greases.
Divinol Fett L 800 can also be used for the lubrication of mechanically highly loaded gears.
Application of Divinol Fett L 800
Divinol Fett L 800 is primarily intended for the lubrication of rotary table bearings in machining centers and linear guides of selected machine tools.
It can also be used in mechanically highly loaded gears where high load carrying capacity, wear protection and adequate lubricant supply are required.
The manufacturer Zeller+Gmelin lists the DMGMoriSeiki approval for Divinol Fett L 800.
What distinguishes Divinol Fett L 800
Very fluid consistency NLGI 000 – facilitates the lubricant's flow and movement in the system.
High load resistance – the result of the VKA four-ball test is 4400 N.
Wear protection – the formulation was developed for mechanically loaded machine elements.
Water and oxidation resistance – supports stable operation of the lubricant in industrial conditions.
Corrosion protection – the product has properties that protect interacting machine elements.
When to choose Divinol Fett L 800
Divinol Fett L 800 is worth considering primarily when the machine manufacturer or technical documentation specifies this lubricant, or when the application requires a grease with a very low consistency NLGI 000, high base oil viscosity, and good flow to the lubrication point.
This product is intended for specific machine applications, therefore when changing from another grease, the device manufacturer's requirements and the compatibility of the previously used lubricant should be verified.

FAQ – Divinol Fett L 800
What is Divinol Fett L 800 used for?
The product is primarily intended for the lubrication of linear guides and rotary table bearings in selected machine tools. It can also be used for mechanically highly loaded gears.
Is Divinol Fett L 800 suitable for DMG MORI machines?
The manufacturer Zeller+Gmelin provides DMGMoriSeiki approval for this product. However, before use, always check the lubrication requirements for the specific machine model and lubrication point.
What does NLGI 000 class mean?
NLGI 000 denotes a very fluid consistency of the grease. In the case of Divinol Fett L 800, it allows for good lubricant flow into the work area. The manufacturer indicates that the product has better flow behavior than a comparable NLGI 00 class grease.
Does Divinol Fett L 800 reduce stick-slip?
Yes. According to the manufacturer, the high viscosity of the base oil effectively reduces stick-slip, which occurs during the movement of mating surfaces.
Can Divinol Fett L 800 be used in gearboxes?
Yes. The manufacturer also specifies that the product is suitable for mechanically highly loaded gears.
Can Divinol Fett L 800 be mixed with another grease?
When changing lubricants, do not automatically assume compatibility between different products. Before changing, check the machine manufacturer's requirements and the compatibility of the existing and new lubricants.
