HOERBIGER strengthens its market position in Slip Rings

HOERBIGER’s Rotary Business Unit expands into maintenance-free slip rings

Waukegan, IL/Littleton, MA, USA, 14 March 2024 – HOERBIGER, a global technology company with 6,000 employees in 43 countries announces the acquisition of Diamond-Roltran, LLC. Diamond-Roltran is the world’s leading manufacturer of maintenance-free slip rings, known as Roll-Rings®. HOERBIGER, in connection with its subsidiary Deublin Company, expands its world-leading position in rotary unions and slip rings. The acquisition is expected to be completed on March 31, 2024.

Deublin provides rotary unions and slip rings for a wide variety of industrial applications and manufacturing processes. With this acquisition, Deublin will expand its existing portfolio to include this unique technology. The entire workforce of Diamond Roltran will be retained and manufacturing will continue at the Littleton, Massachusetts location.

A rolling electrical contact has 1/100 of the friction compared to a traditional sliding electrical contact. The rolling contact slip ring delivers stable performance over its entire lifetime without the need for periodic field maintenance. Roll-Rings® also generate much less electrical noise at high rotational speeds, and are ideal for high power transfer, high speed digital communication transmission and tough environmental conditions, including vacuum.
