PETROFLO R.R. CURVE GREASE

PETROFLO R.R. CURVE GREASE, is a soft, smooth calcium soap grease containing
12% graphite, as a filler. In railway service, PETROFLO R.R. CURVE GREASE, finds
extensive use in trackside lubricators, as a curved rail lubricant. Small quantities are
applied periodically to the inside railhead on sharp curves, where it prevents direct
metal-to-metal contact between the rail, and wheel flange, and reduces the severe wear
which would otherwise result. Because of the extreme pressures generated between
the wheel flanges, and rails as heavy trains negotiate sharp curves, the base grease
acts mostly as a carrier for the graphite. SILOGRAM R.R. CURVE GREASE, is
formulated for excellent “carry” on long curves.
