Introduction to Bearing Technology (Duration approx. 30 min)

​

1. Function of Bearings
Contents:

• The role of bearings in machines: enabling and guiding movement

• Reduction of friction and wear

• Extension of service life and increase in operational safety

Learning Objective:
Trainees understand the basic function of bearings and their importance for machine operation.

​

2. Types of Bearings and Their Characteristics
Contents:

• Rolling bearings:

  • Ball bearings

  • Cylindrical roller bearings

• Plain bearings

• Advantages and disadvantages depending on the application

Learning Objective:
Trainees can distinguish between different types of bearings, know their application areas, and assess their pros and cons.

​

3. Installation and Bearing Arrangements
Contents:

• Difference between fixed and floating bearings

• Bearing arrangements: X arrangement vs. O arrangement

• Importance for axial guidance and thermal expansion

Learning Objective:
Trainees understand proper bearing placement and how bearing forces are absorbed and movements compensated.

​

4. Lubrication and Friction Reduction
Contents:

• Lubrication types to reduce friction:

  • Hydrodynamic lubrication (generated by movement)

  • Hydrostatic lubrication (external pressure supply)

• Selection of appropriate lubricants (oils, greases)

• Influence on bearing service life and maintenance intervals

Special Benefits of VR Training:

• Bearings are rarely visible in real-world operation—VR makes them accessible and can demonstrate function, effects, assembly errors, and more.
