Dry Lubricants: Composed of materials like graphite or molybdenum disulfide, these lubricants are used in high-temperature or corrosive environments where traditional lubricants might fail.
Lubrication Frequency
Regular lubrication is key to maintaining bronze bushings, especially in high-speed or high-load applications. General guidelines suggest lubricating every 50 to 100 operational hours, but always refer to the manufacturer’s instructions for specific recommendations.
Best Practices for Lubrication
-
Clean Before Lubricating: Ensure the bushing is free of dirt and contaminants before applying lubricant. Clean the bushing with a non-corrosive solution and a soft cloth or brush.
-
Select the Suitable Lubricant: Choose a lubricant that matches your equipment’s application and operating conditions (temperature, load, speed).
-
Apply Evenly: Distribute the lubricant uniformly over the bushing surface to ensure all critical areas are covered.
-
Avoid Over-Lubrication: Excess lubricant can attract dirt and debris, which can compromise performance. Apply the right amount as specified by the manufacturer.
