Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Applying force to the outer ring during shaft mounting.Always apply mounting force exclusively to the inner ring when fitting the bearing onto the shaft to prevent brinelling and internal damage.
Improper lubrication leading to premature wear.Ensure the bearing is adequately lubricated with the correct type and amount of grease or oil as specified for the operating conditions.

Common Applications

  • Industrial Pumps and Compressors
  • Conveyor Systems
  • Material Handling Equipment

⚠️ Engineering Warnings

  • Avoid exposing the bearing to extreme shock loads which can exceed its rated capacity and lead to premature failure.
  • Ensure proper sealing is maintained in corrosive environments to prevent ingress of contaminants.
