Installation Procedure

1. Clean bearing and mating shaft/housing with a suitable solvent. Ensure no debris is present. 2. Apply a light, even coating of appropriate lubricant to the bearing raceways and balls. 3. Carefully press the bearing onto the shaft or into the housing using a properly sized arbor press or fixture, ensuring even pressure distribution to avoid brinelling.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-lubrication or under-lubrication.Refer to the manufacturer's lubrication chart for the correct type and quantity of lubricant based on operating speed and temperature.
Applying force to the outer ring when pressing onto a shaft (or vice versa).Always apply force to the ring that is being fitted. Use a proper press or sleeve to ensure force is transmitted through the bearing's rolling elements.

Common Applications

  • Marine equipment and offshore platforms
  • Food and beverage processing machinery
  • Chemical processing plants
  • Pharmaceutical manufacturing equipment
  • Wastewater treatment facilities

⚠️ Engineering Warnings

  • Ensure proper shaft and housing tolerances are maintained to prevent premature failure.
  • Avoid exposing the bearing to excessive shock loads or abrasive contaminants without appropriate sealing.
