Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using excessive force during installation, potentially damaging the bearing's raceways or cage.Employ a proper bearing installation tool or arbor press to apply even, controlled pressure. Utilize induction heaters for controlled thermal expansion of the shaft or housing if necessary.
Introducing contaminants during handling and installation, leading to premature wear and reduced lifespan.Handle bearings in a clean environment and keep them in their original packaging until ready for installation. Use clean tools and gloves.

Common Applications
