Specialty greases are specially formulated for special applications when normal lubricants may not be so suitable. They provide unique performance characteristics, such as resistance against extreme temperatures, water-washout, or protection against high loads. Here is a guide on how to use specialty greases effectively
1. Select the Right Specialty Grease
Temperature Resistance: Depending on the operating environment, special greases should be selected for high or low-temperature applications.
Water Resistance: The grease should be water-resistant or waterproof (marine and underwater applications) if moisture can come into contact with the equipment being lubricated.
Extreme pressure (EP) greases are necessary when heavy loads or shocks are applied to the machinery.
Food-grade greases are to be selected if the grease will have contact with food or pharmaceutical products.
Silicone or graphite-400 greases are used in applications resistant to high temperature or chemical exposure.
When the equipment is in corrosive environments, select a grease that helps protect against corrosion.
2. Application
Clean the Surface: The surface where grease is applied should be clean, dry, and free from dust or debris. Contaminants can interfere with the grease’s performance.
Correct Amount: Too much grease produces friction against a machine and results in wastage, while too little grease leads to inadequate lubrication. Refer to the manufacturer for specifications with regard to how much grease should be applied properly.
Use the Correct Tools: Apply with right applicators-whether a grease gun, brush, or manual application-to ensure proper placement of grease to the correct parts.
3. Frequency of Application
Maintenance Schedule: Specialty greases often specify how frequently they should be applied. Inspection and maintenance must be performed regularly, especially under high load, high temperature, or demanding environment situations.
