Klüberspeed BF 42-12 is designed specifically for high-performance operations that run constantly at high speeds of up to 1,600,000 mm/min and temperatures ranging from -50°C (-58°F) to 120°C (248°F). The Klüberspeed BF 42-12 can help your machine run smoothly by delivering reliable lubrication that stays at the right viscosity (thickness) for prolonged periods of time.

The Klüberspeed BF 42-12 achieves these characteristics with its fully synthetic base oil and special lithium soap thickener, making it the perfect option for a wide range of speeds and temperatures. Thanks to the thermal stability and ageing resistance of its base oil, Klüberspeed BF 42-12 is the perfect grease for motor-powered spindle bearings as well as high-speed milling, grinding, turning and drilling spindles.

By enabling faster running-in and minimising friction-induced heat, Klüberspeed BF 42-12 utilises its exceptional water resistance and low-friction design to prevent premature failure, reduce maintenance costs and extend equipment service life.

Available in a 400g size, Klüberspeed BF 42-12 is suitable for precision lubrication and routine maintenance applications.

Key Benefits For Your Application

Faster Break-in Period

Klüberspeed BF 42-12 shortens the initial running-in process for spindle bearings, helping your machinery reach peak performance much quicker.

Water and Moisture Protection

With exceptional resistance to water washout, Klüberspeed BF 42-12 protects bearings from moisture damage and premature failure, helping to reduce ongoing maintenance costs.

Reliable Performance Across All Temperatures

Klüberspeed BF 42-12 performs reliably in both very cold and very hot conditions, helping equipment run smoothly across a wide range of temperatures.

Cooler Operation and Longer Equipment Life

With a low-friction formula, Klüberspeed BF 42-12 helps reduce heat during operation, keeping bearings cooler and reducing wear. This helps your equipment last longer and perform more reliably.
