ROYCO® 49
GENERAL PURPOSE GREASE
ROYCO 49 is a smooth, buttery, gray-black mineral oil based grease using an inorganic gel thickener
and micro-fine molybdenum disulfide that is compounded with additives to impart oxidation resistance,
water washout, and both fresh and salt-water corrosion protection.
Applications :
ROYCO 49 is intended for use in applications where severe operating conditions may include temperatures as
high as 204 degrees C, low to moderate speeds, high loads, extreme pressure, and a salt water or high
pressure steam environment. It is intended for lubrication of critical components of the shipboard aircraft
catapult system, automotive, and ground support equipment. Specifically, the grease is intended for use in
environments requiring normal high temperatures up to 177 °C (350 °F) or brief exposure to temperatures up
to 204 °C (400 °F). It is also intended for use with systems requiring low speed, high load, salt water, and
contact with high pressure steam. ROYCO 49 should not be used in high-speed anti-friction bearings without
prior performance evaluation.
Features & Benefits :
- ROYCO 49 is composed of a high-viscosity
mineral oil with a non-soap thickener and
molybdenum disulfide
- Extreme-pressure additives
- Fortified with a Corrosion Resistance additive
package
- Extended use at temperatures up to 177°C (350°F)
and for brief periods of use at temperatures up to
204°C (400°F).
- Avoids excessive wear under shock load and low
speed
- Maintains excellent grease performance in adverse
weather or other water-exposure, steam and seawater
related conditions .
