Solutions for belt drives and generators

The belt drive is associated with the combustion engine in the truest sense of the word. Until today, the most important advantages are the high power density, the quiet running, the insensitivity to shocks and the low maintenance requirements.

Here, too, our mission is to get the best out of your vehicle. Just trust our comprehensive understanding of the system.

Typical applications

Belt tensioner

Alongside the alternator, the belt tensioner plays the main role in this system. In your application, high speeds and quiet, low-vibration running are particularly important. To keep CO2 emissions and costs as low as possible, friction and weight must be reduced to a minimum. In addition, you expect the belt tensioner to have a long service life. Once again, the optimum seal is what counts here.

We develop and supply the deep groove ball bearing perfectly tailored to your requirements. On request, we can also provide your solution with a plastic cover.

Alternators and belt-driven starter generators

Similar to an electric motor, the generator or alternator places certain demands on the ball bearings: maximum energy efficiency, high speeds and long service life. One of the ball bearings has to support increased loads due to the belt.

For mild hybrids, there is the special case of the Belt Starter Generator (BSG). This allows you to use additional torque when starting or accelerating. In addition, you reduce the CO2 emissions of your vehicle through the higher efficiency and energy recovery.

Rely on our many years of automotive experience. We are very familiar with your applications and the associated requirements. Find out from us what the ideal bearing solutions for this look like.
