CLPF type gear oils

Basic Identifiers

5977 Gear Oil synthetic 220 CLP-F


The Alpha BMB range are high-performance gear oils with solid lubricant additives (molybdenum disulphide / MoS2). They fulfill the requirements of the DIN 51517-3, and qualify as CLPF type gear ois in accordance with DIN 51502. The MoS2 additives are matched specially to the base oil and other additives, so that a stable suspension can be achieved with the highest efficiency over a broad load range. The remarkable properties of these gear oils results in a neutral behaviour with nonferrous heavy metals and seals, a high thermal loading capacity, good ageing stability and an unusually good protection against corrosion.

ASTM D341 Viscosity Calculator

You may calculate the viscosity of the oil at various temperatures based on ASTM D341. This uses the two sets of calibration data that we already have in order to calculate the viscosity at any temperature. You may input multiple temperatures at once, seperated by comma.
