Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Applying excessive force during installation, leading to premature bearing failure.Use a bearing press or appropriate specialized tools for installation, applying force evenly and gradually.
Not verifying shaft and housing dimensions before installation, resulting in a loose or overly tight fit.Thoroughly measure the shaft and housing bore dimensions and compare them against the bearing's specifications to ensure proper fit.

Common Applications
