Liqui Moly LM 47 Long-Life Grease + MoS2

Liqui Moly LM 47 Long-Life Grease + MoS2

When bearings, sliding surfaces, joints, and heavily loaded mechanical parts operate under demanding pressure, moisture, and temperature conditions, reliable lubrication becomes essential for minimizing wear and maintaining operational stability. Liqui Moly LM 47 Long-Life Grease + MoS2 is a high-grade molybdenum grease formulated with molybdenum disulfide (MoS2) to provide exceptional lubricity, excellent load-carrying capacity, and long-lasting protection under severe service conditions.

At New Tech International is the largest industrial products supplier in the Middle East, we provide professional lubricants, greases, oils, and maintenance solutions for workshops, industrial facilities, fleet operators, and mechanical maintenance teams. LM47 long life grease is available through New Tech as a high-performance solution for heavy duty lubrication, especially where conventional grease may not provide sufficient protection against friction, wear, water exposure, and extreme pressure.

During operation, the MoS2 content forms an ultra-thin, permanently adhering lubricating film on sliding surfaces. This protective layer continues to provide lubrication even if the main grease supply becomes temporarily unavailable, making Liqui Moly LM 47 a strong choice for critical mechanical applications.

 

What Is Liqui Moly LM 47 Long-Life Grease + MoS2?

Liqui Moly LM 47 Long-Life Grease + MoS2 is a special lithium-soap-based Industrial Grease with added molybdenum disulfide.

The MoS2 solid lubricant significantly improves the lubricating properties of the base grease and provides performance characteristics beyond those of standard multipurpose greases.

The product is classified according to DIN 51502 as KPF2K-30 and has an NLGI consistency grade of 2.

Available through New Tech, LM 47 is designed for users who require dependable lubrication under:

• High mechanical loads.
• Extreme pressure.
• Sliding friction.
• Hot and cold water exposure.
• Changing temperatures.
• Long service intervals.
• Industrial and automotive maintenance conditions.

How Does MoS2 Improve Lubrication?

Molybdenum disulfide, commonly abbreviated as MoS2, is a solid lubricant used to reduce friction and wear in highly loaded mechanical contacts.

In LM 47, the MoS2 forms an extremely thin film on sliding and contact surfaces during operation.

Permanently Adhering Lubrication Film

This film adheres to the metal surfaces and continues to provide lubrication over extended periods.

Protection if Grease Supply Fails

One of the most important characteristics of the product is that the MoS2 film continues to lubricate even if the grease supply is completely interrupted for a period of time.

Reduced Friction

The solid lubricant helps reduce sliding resistance between contacting metal surfaces.

Reduced Wear

Lower friction helps reduce wear on mechanical components and supports longer service life.

Long-Life Lubrication Performance

The defining characteristic of LM47 long life grease is its extremely long-lasting lubrication capability.

This is particularly valuable in equipment where:

• Relubrication is difficult.
• Maintenance access is limited.
• Components operate continuously.
• Downtime must be minimized.
• High loads accelerate grease breakdown.
• Lubrication reliability is critical.

The combination of lithium-soap grease and MoS2 provides both conventional grease lubrication and an additional solid-lubricant protection layer.

Heavy Duty Lubrication Under High Loads

Liqui Moly LM 47 is specifically suited to heavy duty lubrication applications.

The product offers very high load-carrying capacity and distinctive high-pressure characteristics.

This makes it particularly useful for mechanical parts exposed to:

• High contact pressure.
• Shock loading.
• Sliding movement.
• Repeated mechanical stress.
• Heavy industrial duty.

Outstanding Load-Carrying Capacity

One of the core properties of LM 47 is its extremely high load-carrying capability.

Under heavy mechanical load, conventional grease can be squeezed away from the contact zone.

The MoS2 content helps provide an additional protective lubricating film that remains on the sliding surfaces.

This combination supports increased operational reliability in demanding equipment.

Extreme Pressure Performance

LM 47 has pronounced high-pressure characteristics, making it suitable as an EP Grease for applications where heavy loads and pressure are present.

EP performance helps protect lubricated components against:

• Surface damage.
• Excessive wear.
• Metal-to-metal contact.
• High-load sliding stress.

This makes the grease useful for machinery, joints, bearings, and other heavily loaded mechanical assemblies.

Friction and Wear Reduction

Liqui Moly LM 47 is designed to reduce both friction and wear.

The grease provides a lubricating film, while the MoS2 layer adds further protection at the actual metal contact surfaces.

This dual mechanism supports:

• Smoother mechanical operation.
• Lower friction losses.
• Reduced wear.
• Longer component life.
• Improved operational reliability.

Water Resistance

LM 47 is particularly resistant to both cold and hot water.

This property makes it useful in equipment that may operate in wet or washdown environments.

Water resistance helps the grease remain in place and maintain lubrication where moisture might otherwise wash conventional grease away.

Corrosion Protection

In addition to reducing friction and wear, LM 47 provides good corrosion protection.

This helps protect lubricated metal surfaces against moisture-related damage and environmental exposure.

The specified Emcor corrosion class is 1/1, supporting its use in demanding mechanical applications.

High Resistance to Aging

Greases can degrade over time as a result of heat, oxidation, contamination, and mechanical stress.

Liqui Moly LM 47 offers high resistance to aging, helping it maintain useful lubricating performance over longer service periods.

This property contributes directly to its long-life lubrication characteristics.

Centralized Lubrication System Compatibility

The product can be delivered through centralized lubrication systems.

This is an important advantage for:

• Industrial machinery.
• Production equipment.
• Large mechanical systems.
• Automated lubrication networks.
• Equipment with multiple lubrication points.

Central lubrication compatibility allows LM 47 to be integrated into maintenance systems that automatically distribute grease to critical components.

Operating Temperature Range

Liqui Moly LM 47 is designed for use across a broad operating temperature range.

The specified range is:

-30°C to +130°C

This allows the grease to function in both cold and elevated-temperature mechanical environments.

The dropping point is specified as greater than 180°C, indicating strong thermal resistance of the grease structure.

Cold-Temperature Performance

At low temperatures, grease can become difficult to pump or distribute.

LM 47 has a specified flow pressure at -30°C of less than 1400 mbar, supporting its use in low-temperature applications and centralized lubrication systems.

High-Temperature Behavior

At elevated operating temperatures, grease must maintain its consistency and lubricating properties.

The lithium-soap thickener and high dropping point help LM 47 remain suitable for mechanical applications operating up to approximately +130°C.

Industrial Grease for Demanding Mechanical Systems

As an Industrial Grease, LM 47 is suitable for a wide range of mechanical lubrication tasks.

Potential applications can include:

• Bearings.
• Sliding guides.
• Shafts.
• Joints.
• Pins.
• Bushings.
• Hinges.
• Mechanical linkages.
• High-load contact surfaces.
• Industrial machinery.
• Automotive components.
• Agricultural equipment.

Specific equipment requirements should always be checked before application.

Is LM 47 a Graphite Grease?

LM 47 contains molybdenum disulfide rather than graphite as its main solid lubricant.

However, users often search for products such as Graphite Grease when looking for solid-lubricant greases designed for high-load conditions.

Both graphite and MoS2 can be used as solid lubricants, but they have different properties and application profiles.

LM 47 should therefore be described specifically as a molybdenum-disulfide grease, not as a graphite-based formulation.

MoS2 Grease vs. Standard Grease

The main difference between LM 47 and a standard grease is the additional solid-lubricant protection provided by MoS2.

Standard Grease	LM 47 with MoS2
Provides conventional grease film	Provides grease plus MoS2 film
General lubrication	Heavy-duty lubrication
Moderate load protection	Very high load-carrying capacity
Limited emergency lubrication	MoS2 film remains after grease loss
Standard friction reduction	Enhanced friction and wear reduction

This makes LM 47 especially useful in high-load applications where additional protection is required.

MoS2 Grease vs. Graphite Grease

Graphite Grease and molybdenum grease are both designed to improve lubrication under demanding conditions, but they use different solid lubricants.

LM 47 uses molybdenum disulfide, which forms a thin adhering film on sliding surfaces.

The correct grease should always be selected according to:

• Load.
• Speed.
• Temperature.
• Material compatibility.
• Water exposure.
• Equipment manufacturer requirements.

EP Grease Characteristics

LM 47 can be considered an EP Grease because of its strong high-pressure properties and load-carrying performance.

EP greases are particularly useful in mechanical contacts where ordinary lubricants may be displaced under load.

Liqui Moly LM 47 provides:

• High pressure resistance.
• Excellent load carrying capacity.
• Reduced wear.
• Friction reduction.
• Emergency lubrication characteristics.
• Long-term protection.
