Special grease for rolling bearings with wide service temperature range

Has your experience with lithium-based greases been so good that you don’t want to abandon them even though requirements have increased? The rolling bearing grease Klübersynth BEH
42-232 is based on a lithium special soap and a special fully synthetic mixture of ester and ether oil. The carefully selected additives prevent premature bearing failure due to material
fatigue even at elevated temperatures and loads. With its wide service temperature range from -40 °C to +180 °C in combination with excellent wear and corrosion protection,
Klübersynth BEH 42-232 is a high-performance grease for a wide range of challenging applications.
Content: 1kg can
Available in 1kg can, 25kg bucket, 180kg drum

Benefits for your application

Longer relubrication intervals than with conventional lithium-based greases
Better pressure absorption capacity due to special EP additives reduces wear
Good compatibility with FKM elastomers
Very wide service temperature grease – extraordinary for a lithium-based grease
High ageing and oxidation stability enable long component life
Optimised oil release reduces friction resistance and contributes to higher efficiency
Designed for a wide range of bearing speeds

Application

Klübersynth BEH 42-232 was especially developed for the longterm or for-life lubrication of heavily loaded rolling bearings. As was demonstrated in tests carried out on FAG FE8 and FAG FE9 rolling bearing testers, Klübersynth BEH 42-232 has performance characteristics enabling it for applications with both linear or point-to-point contact.
Such for-life-lubricated rolling bearings are found e.g. in
– machines for agriculture and the building industry
– conveyors
– textile and paper making-machines
– wheel bearings
