Choosing Lithium Complex Grease for Extreme Load Applications

TL;DR: Prioritize Spanjaard RB2 for mining and construction equipment in Malaysia. This lithium complex grease uses moly (MoS2) solid lubricants to prevent wear under extreme load and extreme pressure. It is specifically designed to avoid melting at high temperatures, making it suitable for any bearing, pin and bush.
 

Features

Spanjaard RB2 Grease utilizes a lithium complex soap thickener combined with molybdenum disulphide to provide solid film lubrication. It contains extreme pressure additives to manage heavy mechanical loads and inhibitors specifically designed to prevent rust and oxidation. The formulation maintains a stable consistency under varying speeds and remains effective when exposed to wet conditions.

Technical Data

• NLGI Grade: 2
• Thickener Type: Lithium Complex Soap
• Color: Black
• Worked Penetration (25°C): 280 (1/10 mm)
• Operating Temperature Range: -25°C to 150°C
• Drop Point: >230°C
• Oil Viscosity (40°C): 210 cSt
• Base Oil Flash Point: 250°C
• Timken OK Load: 27 kg
• Copper Corrosion (24hr/100°C): Pass
• Low Temperature Stability: Pass

Applications

This grease is intended for both slow and high-speed anti-friction bearings, including ball and roller types. In automotive and transport sectors, it is used for wheel bearings, taper bearings, universal joints, and chassis lubrication. Industrial applications include electric motor bearings and bushes. It is frequently applied to machinery in the mining and construction sectors, particularly equipment exposed to dust or high moisture.

Why This Works

The inclusion of molybdenum disulphide creates a physical solid film on metal surfaces. This layer provides a secondary defense when the oil film is squeezed out under extreme pressure or shock loads, preventing metal-to-metal contact. The lithium complex thickener provides a higher drop point than standard lithium greases, allowing it to remain stable at higher operating temperatures without leaking from the bearing. In the Malaysian climate, the rust inhibitors are critical for protecting components against high humidity and tropical rainfall.

Who This Is Suitable For / Not Suitable For

Suitable For:

• Maintenance teams managing heavy transport fleets or construction machinery.
• Industrial operators needing a versatile grease to reduce inventory by covering multiple bearing types.
• Applications subject to frequent vibration or shock loading where standard greases may fail.

Not Suitable For:

• Food-grade environments where non-toxic, H1-certified lubricants are required.
• Extremely high-temperature applications exceeding 150°C continuously.
• Systems requiring a low-viscosity grease for very high-speed, precision instruments.

How to Use

1. Clean the application area and grease nipple thoroughly to remove contaminants.
2. If switching from a different grease type, flush the old lubricant out by applying the new grease until the discharge runs clean.
3. Apply the grease using a manual grease gun or by hand for open bearings.
4. Ensure the bearing housing is filled to the manufacturer’s specified volume—typically one-third to one-half of the free space for high-speed applications.
5. Close the container lid immediately after use to prevent dust ingress.

Common Mistakes to Avoid

• Mixing Incompatible Greases: While compatible with most lithium greases, mixing with non-complex soaps can lead to thinning and grease runoff.
• Over-greasing: Applying too much grease in high-speed bearings can cause churning, leading to overheating and premature failure.
• Contamination during Storage: Leaving the lid open or using dirty applicators introduces grit, which acts as an abrasive inside the bearing.
• Neglecting Flush Intervals: In wet or dusty environments, failing to re-grease frequently can allow contaminants to bypass seals.

Safety & Compliance

The product is manufactured by an ISO 9001 certified company. It is a chemical product and should not be swallowed; medical attention is required if ingestion occurs. Storage should be under cover with the lid securely closed to maintain product integrity. Users should follow standard workshop safety protocols, including the use of gloves to avoid prolonged skin contact.

FAQ

1. Is RB2 Grease waterproof? It is designed to be water-resistant and remains effective in wet conditions, protecting metal surfaces from rust.
2. Can I use this in my car's wheel bearings? Yes, it is specifically formulated for all types of motor vehicle wheel bearings, including those in heavy transport vehicles.
3. What is the benefit of the black color? The black color is a result of the molybdenum disulphide, which provides the extreme pressure protection.
4. What sizes is this grease available in? It is available in various sizes ranging from 400g cartridges for grease guns up to 180kg drums for industrial use.
