066792 Nadella pin G0009018 with roller for HIRTH ring closing cam, Gildemeister DMG-Mori GM16, length 50 mm
(Incl. Tax: €127.37)
Pin and roller assembly Nadella code G0009018 for the Hirth ring opening and closing system used in Gildemeister GM16AC multi-spindle automatic lathes. The component is mounted on the cam-actuated lever and enables motion transmission through the cam-roller contact, allowing the opening of the Hirth ring that locks the main spindle drum in position. The rotating roller reduces friction and ensures smooth kinematic operation and accurate positioning. As a wear component, preventive replacement every 24 months is recommended to protect the Hirth coupling teeth and maintain reliable machine operation.
The Nadella pin and roller assembly code G0009018 is a precision mechanical component used in Gildemeister GM16AC multi-spindle automatic lathes and plays a critical role in the actuation system responsible for opening and closing the Hirth ring that locks the main spindle drum in position.
This component is mounted on the actuation lever connected to the machine’s camshaft system. During operation, cams mounted on the camshafts generate the motion that is transmitted to the roller. Through this cam-roller interaction, the motion is transferred to the lever system controlling the opening of the Hirth ring.
The Hirth ring itself is a key element for the accurate positioning of the spindle drum. The Hirth coupling ensures extremely precise mechanical engagement between the drum and the machine structure, allowing accurate alignment of the machining stations during each machine cycle.
The pin and roller therefore act as the interface element between the cam drive system and the Hirth ring opening mechanism. The roller reduces friction between the cam and the actuation mechanism while ensuring smooth motion transmission and high kinematic stability.
The precision of the contact surfaces and the correct rotation of the roller are essential for reliable operation. Excessive wear of the roller can alter the cam contact profile and affect the opening mechanism, potentially generating abnormal stresses that may damage the Hirth ring teeth.
For this reason, the pin and roller assembly is considered a wear component within the cam actuation system. In industrial environments with continuous 24-hour machine operation and intensive production cycles, preventive replacement every 24 months is recommended to preserve the positioning accuracy of the spindle drum and ensure long-term machine reliability.
Maintaining this component in optimal condition contributes significantly to cam system stability, reduces transmission clearances and protects the Hirth coupling teeth, which are essential for the precision of Gildemeister GM16AC multi-spindle automatic lathes.
