• Suitable for use with thermal oil to 400° C and rotational speeds of up to 2000 rpm (Designed for coating and laminating plants, paper, non-wovens and textile calenders, dryers, rotary reaction vessels)
• Patented separation system prevents the oil contacting atmospheric oxygen, ensuring a much longer service life
• Constant monitoring of the joint possible via a cooling unit
• The joint design significantly reduces the risk of hot oil and oil vapours escaping
• The primary seal is pressure balanced and free running. The seal protector disc protects against coarse contamination. Extra safety is obtained by using an externally loaded mechanical seal
• The secondary seal is subject to low stress due to a cooled barrier fluid
• Insulation of the rotor protects bearings from high temperature and prevents energy loss
• The joint function is monitored by control elements on the cooling unit.

Christian Maier GmbH & Co. KG, Germany introduced the completely new K Series of rotary joints for internal coolant supply of machine tools during EMO 2007.

These new rotary joints are caable of running at speeds of up to 42,000 rpm with a coolant pressure of up to 80 bar.

According to Christian Maier CEO Mr Erich Maier, the main technical feature of the K Series is a new, internationally patented internal thermal regulation system that allows the joint to run dry indefinitely (even at maximum speed).

The K Series can also be used for compressed air of up to 10 bar pressure at maximum speed with minimal lubrication.

A multipassage (or multichannel or multiway) joint has normally more than two internal media passages and can transfer either multiple feeds of the same media or different media.

Typical media used transferred via these joints are hydraulic oil, water, air and gas.

Widely used in turntables, filling machines, injection and blow moulding machines, tool machines, tanning equipment, bottle washing units, steel mills, coiling systems, glass machines, robotics, food machinery and mixers, Maier multipassage joints have proven durabilty and reliability in the most demanding of environments.
