Medium- and large-size girth gear drives remain well lubricated with Kluber Lubrication’s Kluberfluid C-F 3 Ultra operational lubricant. The semi-synthetic product has good adhesion, high pressure resistance and offers wear and tooth flank protection to open gear drives with immersion, circulation or spray lubrication systems, the company reports. The lubricant can be used in operating temperatures up to 120 degrees Celsius, does not clog spray nozzles and will flow freely from gear guards. Kluber adds that the product is free from heavy metals, chlorine, solvents, bitumen and solid particles, and can be used in gear drives in equipment such as rotary kilns, tube mills, drums and similar machinery used in the cement, lime, gypsum, mining and chemical industries and in power plants.
