Case Study 2: A steel mill replaced the bearings in its rolling mill with bronze sleeve bearings. The bearings lasted twice as long as the previous bearings, reducing downtime and increasing production output.
Case Study 3: A power plant replaced the bearings in its steam turbine with bronze sleeve bearings. The new bearings reduced friction by 15%, saving the plant millions of dollars in energy costs over the life of the turbine.
Effective Strategies and Tips
-
Proper lubrication: Bronze sleeve bearings require proper lubrication to ensure optimal performance. Choose the lubricant based on the application and follow the manufacturer's recommendations.
-
Correct installation: Improper installation can damage the bearing and affect its performance. Ensure that the bearing is properly aligned and tightened according to the manufacturer's specifications.
-
Avoiding overloading: Overloading can put excessive stress on the bearing, leading to premature failure. Determine the appropriate load capacity for the bearing and avoid exceeding it.
Advanced Features
-
Grooved bearings: Grooves on the bearing surface can improve lubricant distribution and reduce friction.
-
Flanged bearings: Flanges on the bearing housing provide additional stability and prevent axial movement.
-
Thin-walled bearings: Thin-walled bearings are lightweight and have a reduced cross-section, making them suitable for space-constrained applications.
