With the Berulit GA and Berugear HV series, BECHEM offers a wide selection of oils for all applications. Thanks to the high number of lubricants, a wide range of operating conditions, differences in drive and housing design and numerous types of lubricant supply can be taken into consideration. Both product lines offer reliable wear protection even under the toughest conditions. The Berulit and Berugear series do not contain any solvents or bituminous additives and are free of chlorine and toxic heavy metals.  


Longer service lives and application times, greater operational reliability and cost reduction are just some of the advantages of BECHEM gear and circulation oils. The Berugear product series can also be used for extreme stresses and temperatures, such as those found in the cement industry.

Versatile applicationsBerulit and Berugar series

Berulit and Berugear lubrication oils are suitable for open gear drives of tube mills, rotary kilns, dryers and mixing drums in the cement, lime, paper and fertilizer industry. In addition, they can be used for drying plants, silos, as well as for large drives in mining and for processing coal, ores, and minerals.


They ensure a long service life of the drives together with low consumption rates. Adhesive lubricants in the Berulit and Berugear series can also be used for lubricating ring mounts on excavators, cranes, stacker and reclaimer systems, and converters.

Berugear HV stands for a new generation of light-colored and highly viscous service lubricants. The fluids in the Berugear HV series are intended for use in large open drives with higher requirements concerning operational viscosity, life of lubricating film, thermal stability, low lubricant consumption rates, as well as disposal of the consumed lubricant from the gear ring housing. They can also be used wherever the black color of lubricants that contain graphite is not desired. The lubricants in the Berugear HV series are available in various viscosities and do not contain any solvents, as opposed to the products of other manufacturers.  


Berugear HV fluids were developed to fulfill the requirements of the AGMA 9005 D 94 standard and to meet the demands of many gear manufacturers for highly viscous lubricants. The fluids form very thick, long-lasting and extremely adhesive light-colored lubricating films on the tooth flanks.  


Berugear HV fluids can be used with almost all open gear drives on rotary kilns and tube mills. Best results are achieved when they are used to lubricate open gear drives with a small module, with high circumferential speed, or very long relubrication intervals. Excellent results are also achieved in tough conditions when disposing of the old lubricant from the gear box housing.
