DEUBLIN Company Profile

Deublin is the leading manufacturer of rotary joints for applications in the industrial and renewable energy sector.

Rotary Union is a mechanical device that allows transfer of pressurized fluid from a stationary source into rotating machinery such as rollers, cylinders, tables, spindles, or drives for heating, cooling or transfer of fluid power.

Building on a decade of experience in the implementation of demanding rotary motion applications, Deublin has designed electrical slip rings to meet the requirements in similarly difficult environments. The long-lasting slip ring technology ensures a constant and reliable performance as well as a maintenance-free operation.

All Deublin products are 100% tested before they are made available to the customers and are manufactured using state-of-the-art production processes.

PRODUCT OVERVIEW BY INDUSTRIES

Machine Tool Industry

Deublin rotating unions are used to provide different mediums to a through-spindle-coolant system (TSC) that is required to cool the cutting edge directly, reduce friction and remove chips in high-speed machine tooling operations.

Corrugating Industry

Deublin steam joints for corrugating industry are critical components of corrugators. Self-Supported Steam Joints mount directly onto the roll journal with carbon-graphite bushings that support the steam joint housing, whereas Rod-Supported Steam Joints are mounted onto support rods, secured to the machine frame. This allows the steam joints to withstand side loads applied by the inlet hoses.
