KLUBERPASTE 46 MR 401

Light-coloured high-pressure lubricating paste.

Klüberpaste 46 MR 401 is a multipurpose lubricating paste with selected base oils, lithium soap and special solid lubricant additives.

This versatile multipurpose paste has a wide service temperature range and shows good pressure absorption capacity as well as neutral behaviour towards non-ferrous metals, many plastics and elastomers.

Klüberpaste 46 MR 401 is especially suitable as an assembly lubricant in frictional connections and for thin-film lubrication of all friction points subject to very high pressure loads, low sliding speed, high wear, Stick-Slip and tribo-corrosion.
Typical applications include: press fit assembly of pins and bolts, mounting of rolling bearings, wheels and flanges, lubrication of rolling and plain bearings operating at very low speeds.
Klüberpaste 46 MR 401 is also suitable to prevent running-in damage and stick-slip in components such as threaded spindles, spline shafts, ball and socket joints and rod end bearings.
Its good compatibility with plastics facilitates the lubrication of radial shaft seals (o-rings, v-rings, sealing cups) made of rubber-elastic materials for extended lifetime.
Owing to the many different elastomer and plastic compositions, we recommend compatibility be checked prior to series application.
Before applying Klüberpaste 46 MR 401 it is important to clean the contact surfaces and remove any solvent residues with a lint-free, dry cloth.
Klüberpaste 46 MR 401 can be easily applied to the entire surface in a thin layer with a spatula. It is important to avoid overlubrication.
Before applying the paste to a plastic material we recommend undertaking a materials compatibility test.
The friction values indicated on page 2 in the Section Product Data were determined with two different materials. Other materials/surfaces have to be checked accordingly.

Easy assembly and disassembly of highly loaded frictional connections
Prevents premature material ageing caused by tribo-corrosion and stick slip
Can be used with many material combinations, including plastics and elastomers
