Correct bearing installation in stone machinery is very important, but issues may still arise during assembly, as some details may be overlooked, leading to bearing damage. Here are some key precautions to take when assembling bearings.

 

 

1. Check for Bearing Quality Issues: Ensure the bearing rotates smoothly and inspect the bearing surface for any defects such as dents, burns, cracks, etc. Strictly prohibit the installation of bearings with quality issues.

 

2. Ensure a Clean Installation Environment: Prevent foreign objects from entering the bearing during the installation process.

 

3. Ensure the Bearing is Clean: Only install bearings that have been properly cleaned.

 

4. Ensure Seal Quality: Carefully check that the seal’s model, specifications, and dimensions are suitable. Look for any damage or quality issues. Make sure all related components are complete and that the fit is appropriate.

 

 

1. Avoid Hard Installation or Impact: Always install bearings gently. The bearing and housing should fit with a small gap. Normally, lightly tap the end face for proper alignment. Forcing or striking hard will cause misalignment, making installation difficult and possibly damaging or even scrapping the bearing housing surface.

 

2. Use Induction Heating for Inner Ring Installation: The bearing’s inner ring should be heated using induction heating, with a temperature not exceeding 120°C. Never use an open flame to heat or disassemble bearings.

 

3. If Installation is Difficult, Find the Cause: Identify the problem and take appropriate measures after troubleshooting. If any parts are deformed, they should be repaired promptly. If necessary, revise the drawing.

 

4. Inject Sufficient and Clean Lubricant: Follow the requirement to inject an adequate amount of clean grease into the bearing.

 

5. In case of Defective Seals or Other Components: If defective seals, end caps, or other parts are found during installation, ensure they are scrapped or repaired to guarantee that the assembly quality meets the required standards.
