Tribol 1100

Castrol Tribol 1100 gear oils combine high quality petroleum base oils with the latest developments in the field of surface improving additives designated TGOA. The oil-soluble additive package equalizes surface roughness on interacting surfaces to prevent running-in pitting and reduce friction. It helps extended gear life in heavily loaded gearboxes subject to shock loading.

Alpha SP

Alpha SP gear oils prevent scuffing in heavily loaded applications and are particularly suitable for use in spur or worm gearboxes having either oil bath or forced circulation lubrication. They can also be used in bevel, spiral and planetary gearboxes, pump bearings and crankcases for high pressure mud or cement pumps.
