Sugar Mill Lubricants

Castrol SMR Grades

Castrol SMR lubricants are especially formulated for sugar mill roll bearings and gearboxes. They are viscous black oils fortified with load bearing additives and incorporate emulsifiers to resist the harmful effects of the inevitable contamination with sugar juices encountered in use. They also find use in other heavily loaded open gears and pinions. These grades are now lead free.
