July 2017
Castrol Magna RD Range Oils consist of selected mineral oils specially
compounded with lubricity fortifiers, corrosion inhibitors and tackiness
additives.
Extreme Pressure Requirements:
Rock drill splines are subject to sliding action under intense pressure. To prevent metal-to-metal contact, a lubricant
must have outstanding extreme pressure characteristics. Exceptionally high extreme pressure ratio of 300,000 pounds
per square inch is one of the many reasons that Castrol Magna RD is so effective in reducing wear.
Tackiness:
Castrol Magna RD contains a tackiness agent that provides excellent adhesive characteristics to drill surfaces.
Rust and Corrosion Protection:
Castrol Magna RD provides rust and corrosion protection of all internal parts of the drills, even during extended idle
periods. Serious rust and corrosion is also prevented in the presence of heavily moisture-laden compressed air. Castrol
Magna RD has a balanced additive package that provides good oxidation stability to minimize oxidation and
gumming of any parts exposed to high temperatures.
