What Grease Should Be Used in an Automatic Lubrication System?

Selecting the correct grease is just as important as choosing the right automatic lubrication system. Even the most advanced lubrication equipment cannot deliver reliable performance if the grease is unsuitable for the application.

The ideal grease depends on your equipment, operating conditions, temperature, load, and lubrication system design. Choosing the right product helps improve lubrication efficiency, extend component life, and reduce maintenance costs.

1. Choose the Correct NLGI Grade

Grease consistency is classified by the National Lubricating Grease Institute (NLGI).

The most commonly used grades for automatic lubrication systems are:

NLGI 0 – Suitable for low-temperature environments and long-distance lubrication lines.
NLGI 1 – Offers good pumpability and is widely used in centralized lubrication systems.
NLGI 2 – The most common grease for industrial bearings under normal operating conditions.

Selecting the appropriate NLGI grade ensures the grease flows properly through pumps, distributors, and pipelines.

2. Consider Operating Temperature

Temperature has a significant impact on grease performance.

For different operating conditions:

Standard industrial equipment: General-purpose lithium grease is often sufficient.
High-temperature applications: Use high-temperature grease with excellent oxidation resistance.
Low-temperature environments: Choose grease with good low-temperature pumpability.

Using grease outside its recommended temperature range may result in poor lubrication or premature grease degradation.

3. Match the Load Requirements

Heavy-duty equipment requires grease with excellent load-carrying capacity.

Applications such as:

Steel mills
Mining equipment
Cement plants
Construction machinery

often require Extreme Pressure (EP) grease, which contains special additives to protect bearings and gears under heavy loads.

4. Evaluate Environmental Conditions

Environmental factors should also influence grease selection.

For example:

Wet environments: Use water-resistant grease.
Dusty conditions: Choose grease with strong sealing and anti-wear properties.
Corrosive environments: Select grease with anti-corrosion additives.
Food processing equipment: Use food-grade grease that complies with relevant safety standards.

The correct grease helps maintain reliable lubrication even under harsh operating conditions.

5. Ensure Compatibility with the Lubrication System

Not all greases are suitable for automatic lubrication systems.

The grease should:

Flow smoothly through pumps and pipelines
Be compatible with progressive or dual-line distributors
Maintain stable consistency during operation
Resist oil separation
Provide long-term lubrication performance

Poor-quality grease may block distributors or cause unstable grease delivery.

Common Grease Types

Some of the most commonly used industrial greases include:

Lithium grease
Lithium complex grease
Calcium sulfonate grease
Polyurea grease
Synthetic grease
Extreme Pressure (EP) grease

The best choice depends on your specific application rather than a single "universal" grease.

Can One Grease Be Used for Every Machine?

The answer is no.

Different equipment operates under different conditions, and using one grease for all machines may reduce lubrication performance.

Factors such as speed, load, temperature, contamination, and bearing type should all be considered before selecting grease.

A professional lubrication supplier can recommend the most suitable grease for your equipment.
