FAQ

Besides the current qualities, SOTULUB has four (4) special grease formulas that it is capable of manufacturing if the market demand makes it economically sound:

• HT 4043 grease used for equipment operating in tough conditions, such as hot air fan bearings, press columns, stove doors, etc.
• PYRAGRAISSE 3547 grease used for lubricating equipment exposed to heat: tunnel kiln carriages, hearth rollers, sieves operating at high temperatures, etc.
• MOLYSTABIL 1430 grease intended for bearing blocks, rails, slewing rings of articulated cranes, etc.
• TRACTA 1391 grease intended, on the one hand, for the impregnation of textile tube cores of large cable carriers (such as cableways) and, on the other hand, for the maintenance of metal cables.

The grease performance is expressed through its physico-chemical properties, such as penetration, the dropping point, resistance to oxidation, the wheel hearing test, the anti-rust test, copper strip corrosion, etc.

The grease color only comes into play for marketing reasons, by making it more attractive. Otherwise, as contrary to some opinions, it does not affect, in any way whatsoever, the level of performance of the grease.
