Product Description
Beacon EP 2 Moly is a premium quality multi-purpose, lithium-base NLGI No 2
grease recommended for general industrial applications. It contains an
extreme-pressure additive for increased load-carrying ability. Additionally,
it contains molybdenum disulfide (also known as moly and MoS 2 ), which
enhances the anti-friction properties of the grease under boundary lubrication
conditions. Beacon EP 2 Moly is dark gray and has a smooth, buttery texture.
It is water resistant, has excellent oxidation and mechanical stability, and
protects against corrosion.
Features and Benefits
Molybdenum disulfide offers particular advantages under boundary lubrication
conditions, especially where sliding or vibration action pushes the grease
away from the contacting surfaces. It provides a measure of protection against
fretting and is therefore recommended where this phenomenon is a problem, as
in splined shafts, pivot pins, fifth wheels, and other parts subjected to
oscillating or sliding motion. Also, where relubrication is infrequent,
molybdenum disulfide provides extended lubrication protection.
Beacon EP 2 Moly multi-purpose grease offers the following features and
benefits:
- Wide range of industrial and automotive applications
- Fortified with extreme-pressure additives for heavy loads
- Contains molybdenum disulfide for extra protection in oscillating, sliding, or vibrating applications
- Excellent oxidation stability, water resistance, and corrosion protection
Applications
Beacon EP 2 Moly is suitable for plain bearings and gears. It also can be used
in rolling contact bearings, but is not generally recommended for
high-precision rolling contact bearings because of the possibility of
molybdenum disulfide building up in the clearances. Beacon EP 2 Moly has
applications in the construction, mining, and farming industries. In
off-highway trucks and other vehicles, it provides excellent service in bucket
pins, rack and pinion gearing, fifth wheels, steering gears, etc.
