The O-arrangement is an arrangement of at least two bearings where the pressure center is outside the bearing points.

• Question: Why can an O-arrangement absorb greater tilting moments than the X-arrangement?
  • Answer: In an O-arrangement, the distance between pressure centers is greater, allowing it to absorb larger tilting moments than an X-arrangement.

• Question: How does heat development during operation affect the O-arrangement?
  • Answer: The heat development during operation affects the bearing preload differently. In an O-arrangement, the preload decreases with a more heated shaft.
