Klüber Klüberpaste ME 31-52
Lubricating and assembly paste
Application Klüber Klüberpaste ME 31-52
Klüberpaste ME 31-52 can be used for the assembly of frictional connections, e.g. annular springs or split taper sleeves, and positive connections, e.g. bearing seats, profiled guides, etc. The product has proven particularly successful in the lubrication of clamping chucks. High precision and constant clamping forces are essential requirements in chucks. Any decrease of the clamping force may cause tools or workpieces to become loose. Klüberpaste ME 31-52 improves the sliding behavior of moving chuck components, enables a good transmission of clamping forces and may therefore be used in all types of chucks, such as scroll, cam and spiral chucks. Because of the raw materials used, Klüberpaste ME 31-52 complies with the current chemicals law. It prevents stick-slip and protects against tribo- and fretting corrosion in frictional or positive connections.
Performance, Features & Benefits of Klüber Klüberpaste ME 31-52 are:
- Low lubricant costs for initial and relubrication due to thin lubricant films
- Good wear and corrosion protection helps reduce assembly forces and screw torques and prevents tribo- and fretting corrosion
- High pressure absorption capacity enables constant high clamping forces and consequently ensures properly fixed tools or workpieces in machine tool chucks.

Product Description Klüber Klüberpaste ME 31-52
Klüberpaste ME 31-52 is a white/beige lubricating paste on the basis of mineral oil, calcium complex soap and inorganic solid lubricants. Besides its application as a universal assembly paste, this product offers benefits especially in friction points with small to minimum motion under high static and dynamic loads.

Application notes
Clean and degrease the surfaces thoroughly. Then apply the paste in a thin, coherent layer by means of a brush or cloth that does not fray (do not rub in).
