A Detailed Guide to Grease Selection

Here is a more detailed guide to grease selection:

Identify equipment conditions

1. Equipment type: Different types of equipment, such as bearings, gears, chains, etc., have different requirements for grease.

2. Operating temperature range: Accurately understand the highest and lowest temperatures of the equipment during normal operation. High temperature conditions require high temperature resistant grease

Consider load pressure

1. Light load: Choose a grease with a softer consistency (NLGI 00 - 1), such as calcium or lithium grease.

2. Medium load: Suitable for medium viscosity (NLGI 2) grease, such as general lithium grease.

3. Heavy load: Choose a grease with high viscosity (NLGI 3 and above) and good extreme pressure resistance, such as complex lithium or polyurea grease.

Pay attention to the operating speed

1. Low speed: You can choose a grease with a higher viscosity to provide sufficient oil film thickness and load-bearing capacity.

2. High speed: Choose grease with lower viscosity to reduce friction and heat generation, and prevent the grease from being thrown out due to centrifugal force.

Environmental factors

1. Humid environment: Prefer grease with good water resistance, such as aluminum-based or composite aluminum-based grease.

2. Dusty environment: Grease with good dustproof performance and sealing is required.

3. Chemically corrosive environment: Choose special grease that can resist the erosion of corresponding chemicals.

Compatibility

1. Compatibility with sealing materials: Make sure that the grease will not damage the seals of the equipment.

2. Compatibility with other lubricants: If the equipment has been used with other lubricants before, make sure that the newly selected grease is compatible with it.

Cost and maintenance plan

1. Cost factors: Choose grease with high cost performance while meeting performance requirements.

2. Maintenance cycle: According to the maintenance plan of the equipment and the service life of the grease, choose the appropriate product to reduce maintenance costs and downtime.
