Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Applying excessive force or impact during mounting, leading to brinelling or deformation of raceways.Utilize a proper bearing press or induction heater for controlled mounting. Avoid direct hammering on the bearing's outer ring or cage.
Incorrect or insufficient lubrication, resulting in premature wear and heat buildup.Consult the bearing manufacturer's lubrication guidelines for the specific application and operating conditions. Ensure a consistent supply of appropriate lubricant.

Common Applications

  • Electric Motors
  • Conveyor Systems
  • Gearboxes

⚠️ Engineering Warnings

  • Do not exceed the bearing's rated load capacity to prevent premature failure.
  • Protect the bearing from excessive contamination (dust, dirt, moisture) during storage and operation.
