Gear Oils

GENERAL DESCRIPTION:

SF-440 gear oils are fully formulated synthetic lubricants specially designed for use in highly rated worm gear units. They have an extremely high viscosity index, low pour points, and high load-carrying capacities, and show exceptionally low coefficients of friction. Additives are incorporated to reinforce the stability of these oils, their resistance to corrosion, and their resistance to scuffing under unfavourable operating conditions. These oils are capable of extremely long service life.

SELCO SF-440 being POLYGLYCOL, and not mineral oil-based, exhibits inherently superior properties particularly with respect to outstanding thermal stability and lubrication performance. These properties are particularly useful in heavily loaded mechanisms operating at elevated temperatures, e.g., worm gears and calendar bearings.

APPLICATIONS:

SELCO SF-440 is suitable for heavy-duty automotive and industrial gearboxes with sump temperatures up to 140°C. The product performance allows for extended drain intervals and even, in some cases, for operation as a “fill for life” lubricant.

The specially developed polyglycol-additive technology of the new SELCO Synthetic Industrial Lubricants SF-440/220 and SF-440/460 allows thermal stable operation at temperatures in excess of 200°C. These products are therefore preferred for the lubrication of gears and bearings operating at elevated temperatures, e.g., in calendar equipment.
