Installation Procedure

1. Clean the shaft and housing bore thoroughly to remove any contaminants. 2. Apply a thin layer of appropriate lubricant to the shaft and the inner ring of the bearing. 3. Carefully press the bearing onto the shaft, ensuring it is seated squarely and evenly. Avoid applying excessive force to the outer ring. 4. If mounting into a housing, ensure the housing bore is clean and properly dimensioned, then press the bearing into place.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using incorrect tools for pressing the bearing, leading to damage of the raceways or seals.Utilize a proper bearing press or a bearing installation kit with correctly sized mandrels that apply force to the inner ring for shaft mounting and the outer ring for housing mounting.
Introducing dirt or debris during installation, compromising bearing life and performance.Maintain a clean work environment and handle the bearing with clean hands or gloves. Inspect the bearing and mounting surfaces for any signs of contamination before assembly.
