Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Applying excessive force during installation, leading to brinelling or deformation.Use a proper bearing press or a controlled heating/cooling method for installation, ensuring even pressure is applied to the ring being mounted.
Incorrect lubrication leading to premature wear or overheating.Consult the bearing manufacturer's lubrication guidelines and ensure the correct type and amount of lubricant are used for the operating conditions.

Common Applications

  • Industrial gearboxes
  • Heavy-duty conveyor systems
  • Agri-machinery drivetrains

⚠️ Engineering Warnings

  • Ensure proper sealing to prevent contamination, especially in harsh environments.
  • Do not subject the bearing to shock loads or misalignment, as this can lead to premature failure.
