Klüber Klübersynth J 44-402


Klüber Klübersynth J 44-402 is a special synthetic grease for ball joints in chassis components


Benefits for your application


– Low breakaway and running torques even after 24 hours of inoperative position
– avoidance of cracking and stick-slip noise
– Particularly low friction values
– smooth running of joints even with high torsion
– Good low-temperature behaviour
– consistent smooth operation




Klübersynth J 44-402 consists of fully synthetic base oil, lithium soap and additives increasing the ageing resistance and the corrosion protection of steel surfaces. Special additives increase adhesion on steel and plastic components, improve the dampening effect between the friction bodies and reduce the breakaway and running torques in ball joints. Klübersynth J 44-402 has been designed to reduce slick-slip and to keep friction values and the difference between static and dynamic friction as low as possible. The usual seal materials like chlorobutadiene rubber (CR) were taken into consideration when developing the grease. Prior to series application we recommend testing the compatibility with the elastomers and plastics used.




Klübersynth J 44-402 is used for sealed joints in e.g. stabilizers, transverse links and wheel joints in the car industry. The grease has been tested in steel/POM pairings subject to oscillating tilting and slewing motions. Klübersynth J 44-402 was developed and tested in cooperation with renowned car manufacturers.


Application notes


Klübersynth J 44-402 can be applied by brush, spatula, grease gun, automatic metering systems and central lubrication systems.
