1. Positioning: Mark mounting positions accurately on the base structure according to equipment specifications. Ensure proper alignment of bolt holes and orientation with machine layout.
2. Hoisting: Use appropriate lifting equipment to raise the bearing steadily above the installation area. Lower slowly while maintaining horizontal and vertical alignment to prevent collisions.
3. Initial Mounting: Align mounting holes and insert bolts loosely to allow for fine adjustments during alignment process.
4. Alignment Adjustments: Use level gauge for flatness measurement, shim as needed. Check perpendicularity with plumb line. Verify uniform clearance using feeler gauge per design specifications.
5. Final Fixing: Tighten bolts in cross pattern using torque wrench to specified torque values for even load distribution.
6. Post-Installation Checks: Visually confirm all bolts are secure. Perform rotation test for smooth motion without noise. Verify lubrication system functionality and seal effectiveness to prevent contamination.
