When Siemens set a demanding benchmark of 100 million maintenance-free revolutions for their wind turbine pitch control slip ring, we saw it not just as a requirement—but as a challenge worth exceeding.

We’re proud to announce that our slip ring achieved 240 million revolutions during testing—2.4 times the original specification. That equates to roughly 20 years of real-world operation.

But this achievement goes beyond the numbers. It reflects our commitment to engineering excellence, precision, and long-term reliability. Credit goes to the BGB Design team, whose innovation and attention to detail made this result possible.

The performance not only surpassed Siemens’ expectations—it led the OEM to position the BGB slip ring as an upgrade option, recognising its outstanding return on investment and superior total cost of ownership.

At BGB, we don’t just meet the standard—we raise it.
