Installation Procedure

1. Ensure the bearing seating surfaces on the shaft and housing are clean and free from burrs or debris. 2. Apply a light, even coat of appropriate lubricant to the bearing raceways and the shaft seating surface. 3. Carefully press the bearing onto the shaft, ensuring it is seated squarely and to the specified interference fit. If pressing into a housing, ensure the housing bore is clean and the housing is at the correct temperature for a slip fit or controlled press fit.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Applying excessive force during installation, leading to brinelling or damage to the raceways.Utilize a proper bearing press or induction heater for installation, ensuring force is applied to the inner ring when mounting on a shaft and to the outer ring when mounting in a housing.
Contaminating the bearing during handling or installation, reducing its lifespan.Keep the bearing in its original packaging until immediately before installation. Handle with clean, lint-free gloves and avoid exposing the bearing to dust, dirt, or moisture.

Common Applications

  • Food processing machinery
  • Chemical processing equipment
  • Marine and offshore applications
  • Outdoor industrial equipment
  • Conveyor systems in corrosive environments

⚠️ Engineering Warnings

  • Ensure proper lubrication is applied before and during operation to prevent premature wear.
  • Avoid operating the bearing outside its specified load and speed ratings, as this can lead to premature failure.
