Solutions for white goods

Smart solutions are needed to make living spaces both functional and comfortable. For example, household appliances should not only save energy but also be as quiet as possible. Here, the choice of the right ball bearings is of critical importance.

Typical applications

Drum

In the washing machine, the drum bearing is a particularly demanding challenge. For a high energy efficiency class, the bearings must be particularly low-friction. In addition, no loud noises should occur during the washing process. And finally, the drum must be able to move high loads at different speeds for as long as possible.

To absorb the high centrifugal forces, we use a GCr15 steel that has been degassed under vacuum for your ball bearings. Non-metallic inclusions are thus reduced and the service life of your application is extended.

Your requirements

  • Maximum energy efficiency
  • Quiet, low-vibration operation
  • High centrifugal forces
  • Long service life

The first question here is how the drum is driven: directly or via a belt. Both philosophies have their advantages and disadvantages. Certainly, the direct drive puts a little more strain on the ball bearing. In order to save installation space, the focus is increasingly on higher power density and thus on smaller ball bearings.

What remains the same are the classic requirements for the bearings in terms of operating life as well as energy efficiency and low noise. Simply ask our experienced application engineers for advice on choosing the right ball bearing.

Your requirements

  • Robustness
  • Long service life
  • Maximum energy efficiency
  • Quiet operation
  • Little installation space
