KLUBERGREASE BE 71-461

As an operator or OEM of large installations where rolling bearings run under high loads, you have to observe a wide variety of influences: to ensure trouble-free operation, reduce downtime and increasing pressure for cost savings.

Klübergrease BE 71-461 is a high-temperature mineral oil grease with a polyurea thickener that has been tried and tested over many years. The product offers a wide service temperature range up to 180 °C, or with continuous relubrication even 200 °C. Klübergrease BE 71-461 offers strong antiwear properties, very good adhesion and resistance to water. Klübergrease BE 71-461 is also highly resistant to oxidation and protects your bearings reliably against corrosion. All these effects help to reduce your maintenance expenses at a very moderate lubricant purchase cost.

Besides lubrication directly at the individual lube point by means of grease gun or lubricant dispenser (e.g. Klübermatic NOVA), Klübergrease BE 71-461 can also be applied to high temperature areas conveniently via centralised lubrication systems, e.g. in

support roller bearings in continuous casting installations
load roller bearings in continuous furnaces

Such applications involve particularly taxing requirements for our lubricant such as high operating temperatures, slow to medium speeds, variable loads, presence of water and hence a corrosive effect. Our Klübergrease BE 71-461 is the ideal choice for these applications, but it may also be used for many other hightemperature lubrication points, e.g. in:

annealing furnaces or drying kilns
plain bearings in foundry cranes
high-temperature rollers in paper and cardboard factories
road surfacing machines
bulk material gate valves
cooling beds, conveyors
rotary kilns
machines and installations in the automotive, beverage, glass and ceramics industries

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.

Considerable cost savings through

an attractive price-performance ratio
lower lubricant consumption due to high thermal stability
lower waste water disposal costs as the product is highly resistant to water, leading to lower contamination

Longer maintenance intervals due to good load-carrying capacity and good resistance to wear and corrosion
Easy and convenient application due to good pumpability and metering via centralised lubrication systems
