Contact Angle
In practice, the following may affect the bearing contact
angle at critical operating speeds and temperature conditions:
- high interference fitting of races
- temperature differential between the outer and inner races
- centrifugal force effects on the balls and rotating race
Neglecting these possible problems could lead to rapid bearing
failure.
Where there is concern about contact angle changes, SNFA will
analyze the situation using the most up to date methods.
The choice of the contact angle requires careful application
analysis keeping in mind at all times the final performance
requirements.
