XYC700 High-Load MoS2 Grease Used for Lubricating Transmission Pins Bearings and Heavy Machinery Components

1.Description

Molybdenum disulfide (MoS₂) is a grayish-black solid lubricant with a layered crystal structure, which enables it to form a solid lubricating film with a low coefficient of friction at the friction interface. When MoS₂is added to grease in the form of fine powder, it can significantly improve the anti-wear and load-carrying capacity of the grease. It demonstrates significant advantages in heavy-load, high-pressure, and extreme condition lubrication fields, making it an ideal agent for lubricating transmission pins, bearings, and heavy machinery components.

2. Characteristics

MoS₂ Content: Generally 3%–5% (by weight), varying according to application load and brand formula.

Consistency (NLGI Grade): Common grades are 1, 2, and 3, catering to different operational requirements.

Drop Point: Some products can reach over 170°C, suitable for high-temperature working environments.

Operating Temperature Range: From low temperatures to several hundred degrees Celsius, with some advanced synthetic formulas providing continuous lubrication under extreme conditions.

3. Advantages

High Anti-wear Capacity

MoS₂ particles form a stable solid lubricating film in high-pressure contact areas. Even if the liquid lubricating oil film is disrupted, MoS₂ can effectively isolate the friction surfaces, reduce metal-to-metal contact, and significantly extend the lifespan of components.

Outstanding Load-carrying Capacity and Extreme Pressure Performance

Due to the presence of the solid lubricating layer, MoS₂ grease outperforms ordinary greases in terms of compressive and impact resistance in high contact stress areas such as transmission pins, pins, and pivots.

Wide Temperature Adaptability

Some high-performance MoS₂ greases maintain lubrication stability from extremely low to several hundred degrees Celsius, making them suitable for high-heat and high-load scenarios.

Corrosion Resistance and Extended Maintenance Cycles

The addition of MoS₂ and anti-oxidation, anti-rust additives reduces oxidation and corrosion, enhances the long-term protective performance of the grease, and lowers maintenance frequency.

4. Applications

MoS₂ grease is particularly important in areas such as transmission pins, pin connections, heavy-duty bearings, and mechanical joints, which are subject to high loads, high impacts, and wear, where conventional greases tend to fail:

Heavy Machinery (e.g., construction equipment, mining machinery)

In vibrating and oscillating conditions, MoS₂grease protects metal surfaces under vibration and compression, reducing wear.

Automotive and Equipment Transmission Systems

In components such as vehicle transmission pins, hinges, and casting machines, MoS₂ grease is widely recommended due to its excellent extreme pressure performance.

Industrial Manufacturing and Steel Industry

In high-load, high-impact lubrication requirements for bearings and friction pairs, MoS₂ grease significantly improves equipment reliability.
