Glossary

The X-arrangement is a bearing arrangement where the pressure center is located between the bearing points.

• Question: For which applications is the X-arrangement suitable?
  • Answer: It is particularly suitable for applications with predominant force application between the bearing points.

• Question: How are forces transmitted in an X-arrangement?
  • Answer: In an X-arrangement, the force flow changes when the contact angles of the rolling bearings are arranged differently. The force flow occurs in the direction of the roller surfaces, making this arrangement particularly suitable for applications with predominant force application between the bearing points.

• Question: How does heat development affect bearing preload in an X-arrangement?
  • Answer: In an X-arrangement, the preload increases with a more heated shaft. For this reason, the choice between X- and O-arrangement depends on the operating conditions.
