DERILL® A619-A2 extreme pressure grease
DERILL® A619-A2   extreme pressure grease
Product introduction:

 

DERILL A619 Series High Load Grease is a high quality grease designed for the bearing of low speed, heavy-duty, whose working environment is poor. It uses the selection of base oil and special thickener, and matching by additive combination of high-tech. It has high drop point and significant mechanical stability, can bear high load, water resistance, corrosion resistance is strong, specially developed for the ambient conditions at low speed and heavy bearing grease. 

 

It uses the high viscosity of base oil and special preparation of lithium calcium thickener, thus it has excellent adhesive force, structural stability, high strength oil film and outstanding waterproof performance. It also has outstanding structure stability under the situation of water, still keeping the outstanding performance in the water environment. 

 

DERILL A619 Series High Load Grease carefully selected and proper additive combination can provide excellent performance, such as excellent anti-wear protection (four ball load > 500 kg), excellent oxidation resistance, corrosion resistance and corrosion resistance performance. Compared with the traditional grease, DERILL A619 Series High Load Grease can maximize the extended in fat interval, and prolong the service life of bearing, reduce downtime and maintenance costs, achieve higher productivity.
 

Typical applications

 

Meet the various requirements of various industrial bearings manufacturers specified.

 

Multi-purpose extreme pressure grease, Special designed for industrial bearings of work Under the condition of damp, high temperature and overloading.

 

Can be used as a multipurpose extreme pressure grease, can be widely used in water and grease often contact conditions (in a damp, water environment of textile machinery, paper-making machinery).

 

With the research and development products,Product information in shown here may be change,Typical nature of the product will also change slightly.Without prior notice.
