Rotary Units for Rotary Indexing Tables
The reliable supply of media to rotating components is often critical to a product’s success.
Our rotary union combines the highest quality with a compact design — reliable, precise, and specifically developed to meet the demanding requirements of rotary indexing tables.
It enables the safe transmission of media, signals, and data even at high rotational speeds and variable indexing cycles — from the food industry and automation technology to microchip manufacturing.
The requirements for rotary unions used on rotary indexing tables depend on the individual design of each system. Our engineers work closely with customers to develop customized solutions that meet all requirements in the best possible way.
Compact Design for All Rotary Table Applications
Early involvement of KONSTANDIN in media feed solutions during machine development often results in a more economical solution than retrofitting onto predefined structures.
Our rotary unions stand out with their minimal diameter, which allows for multiple, separate media connections. Thanks to radial connections, installation is straightforward and efficient.
KONSTANDIN’s versatile developments enable the transmission of gases and liquids, as well as the transfer of signals and data of all kinds to the rotary table, including Profibus, Ethernet, or Fast Ethernet.
Your Advantages with a High-Performance Rotary Union
- Custom geometry for optimal integration into rotary indexing tables
- Minimum diameter with maximum media versatility
- Axial connections to reduce installation space
- Modular design: compatible with Profibus, Ethernet, or Fast Ethernet
- Highest quality even at high speeds and in harsh environments
- Proven solutions for international machine manufacturers
