66 years of cooperation: SENNEBOGEN and Rothe Erde

The Lower Bavarian manufacturer of material handling machines and crane technology SENNEBOGEN and the North Rhine-Westphalian manufacturer of slewing bearings Rothe Erde are celebrating the 66th anniversary of their successful collaboration in 2025. Rothe Erde has been supplying slewing bearings for SENNEBOGEN machines since 1959.

As a traditional, family-run company, SENNEBOGEN Maschinenfabrik can look back on 73 years of success. With a wide range of solutions for the construction industry and material handling, the Lower Bavarian company, which now has over 2,200 employees, plays a leading role in various sectors. With carriers, material handlers, telescopic handlers, cranes and duty cycle crawler cranes up to an operating weight of 420 t, SENNEBOGEN offers its customers the greatest variety of industry- and customer-specific solutions.

As one of the world's leading producers of slewing bearings, thyssenkrupp rothe erde specializes in the development and production of rolling bearings and seamless rolled rings. In close cooperation, the more than 6,000 employees of the Dortmund-based company develop customer-specific solutions for mechanical engineering that are unique in terms of design, material properties and performance.

SENNEBOGEN-cooperation Rothe Erde-Thyssen Krupp — A partial replica of the first ball bearing was ceremoniously presented to the company's own Erich Sennebogen Museum as an exhibit.

"...a reliable basis for our innovative premium products"

It all began in 1959 with a double-row ball bearing that was sent on its journey from the Ruhr region to Lower Bavaria. "Today, we supply everything from single-row ball bearings for material handling machines with small jib lengths to three-row roller bearings for port cranes with a load capacity of up to 90 tons for almost the entire SENNEBOGEN portfolio," explains Alexander Jerrhof, Sales Industry Account Manager at Rothe Erde.

Erich Sennebogen, Managing Director of SENNEBOGEN, adds: "The quality and reliability of Rothe Erde's components have formed a dependable basis for our innovative and reliable premium products for decades. We appreciate the long-standing cooperation and look forward to many more years of joint innovation."

To mark the anniversary, Peter Küpper and Alexander Jerrhof from Rothe Erde presented the company's own Erich Sennbogen Museum with a double-row ball bearing that is identical in construction to the first model supplied in 1959.
