Installation and Fitting Points
**Before installation, clean the journal, inner ring, and roller assembly to remove iron filings and oil.** Use cold pressing for installation; pressure ≤30kN. Do not strike the inner ring end face to avoid deformation.

The journal fit tolerance is k6. The interference fit between the inner ring and the shaft should meet the requirements. After installation, the inner ring end face should fit snugly against the shaft shoulder without gap, and rotation should be smooth.

During installation, assemble the inner ring, outer ring, and roller assembly according to the original factory matching marks, ensuring a preload of 0.05-0.10mm and axial clearance.

Use a special puller for disassembly to avoid damaging the journal. When replacing, check that the journal wear is ≤0.05mm. If it exceeds this tolerance, the entire shaft assembly must be replaced simultaneously.
