KLUBERSYNTH BEM 44-4600

Do you operate low-speed gearboxes and bearings under demanding conditions, e.g. strong vibrations, low or constantly changing ambient temperatures? Often those applications are located where maintenance is complicated and its reduction to a minimum is therefore desirable.

Klübersynth BEM 44-4600 is a modern high-performance fluid grease based on a high-viscosity synthetic hydrocarbon oil and a special lithium soap, which opens up new possibilities for ensuring a reliable operation of your installations.

Carefully selected additives provide Klübersynth BEM 44-4600 with an exceptional scuffing resistance. Klübersynth BEM 44-4600 has passed both the scuffing load test acc. to DIN ISO 14635-3 for fluid gear greases and the standard scuffing test acc. to DIN ISO 14635- 1 for gear oils with top ratings. Klübersynth BEM 44-4600 protects your components reliably against wear, even when subjected to oscillating movements.

When switching from a conventional gear oil to Klübersynth BEM 44- 4600 maintenance works to replace seals are reduced to a minimum. Here, Klübersynth BEM 44-4600 offers you a high operational reliability and significant cost reduction. It is very resistant to oxidation at high temperatures and is also suitable for low temperatures.

Your technical challenges may be found in general industrial equipment, machine tools, heavy industry equipment (mining and cement), robotics, chemical and agricultural machinery.

Examples are:

Crushers, vertical roller mills, hammer mills
Mobile drilling equipment
Cranes, e.g. harbour or mining
Mixer and reactor drives
Harvesting machines
Conveyor belt drives

You can apply Klübersynth BEM 44-4600 by an automatic lubrication system or via an automatic single-point lubrication system. If you wish to optimise the service life of your equipment or have any other questions regarding your application, our experts will be pleased to help you with application-specific advice.

Excellent scuffing resistance similar to that of a gear oil
Special additives ensure excellent wear protection of gear teeth and bearings
Better sealing effect than with gear oils
Wide service temperature range due to modern fully-synthetic base oil
