Installation Procedure

1. Ensure bearing seating surfaces are clean, free from debris, and within specified tolerances. 2. Apply a thin, even layer of appropriate lubricant to the shaft and inner ring before mounting. 3. Carefully press the bearing onto the shaft using a suitable arbor press or induction heater, ensuring even pressure distribution. Avoid hammering directly on the bearing rings.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening the shaft fit, leading to premature bearing fatigue.Adhere strictly to the recommended shaft fit tolerances and use calibrated measuring tools to verify interference.
Contaminating the bearing during installation by not using clean tools or environment.Maintain a clean work area and use clean, lint-free cloths and tools when handling the bearing and its components.

Common Applications

  • Corrosive industrial machinery
  • Food and beverage processing equipment
  • Marine and offshore applications

⚠️ Engineering Warnings

  • Ensure proper lubrication is maintained throughout the bearing's service life to prevent premature wear and failure.
  • Avoid exceeding the maximum rated speed and load capacity to ensure optimal performance and longevity.
