GN-120 – Rubber Flex Disc – Mercedes Application – Bolt Circle Dia 90MM – Disc Width 23MM

GN-120 is a Rubber Flex Disc specifically designed for various Mercedes models including the 190ER, 200ER, 220ER, 230ER, 250ER, 280ER, and 300ER. This component plays a crucial role in absorbing torsional vibrations between the transmission output and the driveshaft input, ensuring a smooth and efficient operation. One of the standout features of the GN-120 is its ability to compensate for minor angular misalignment, which eliminates the need for a universal joint in certain applications. This design choice not only simplifies the driveline but also significantly reduces noise, vibration, and harshness (NVH) experienced in the cabin.

Key specifications of the GN-120 include:

• Mercedes Application
• Bolt Circle Dia: 90MM
• Bolt Hole Count: 6
• Bolt Hole Dia: 14MM
• Disc Width: 23MM

When installing the GN-120, ensure to check the bolt orientation and alignment arrows to maintain proper function. Torque the bolts to specification in a star pattern to avoid uneven stress on the disc. Regular inspections for cracks or deformation at the reinforcement sleeves are essential to prevent failure symptoms such as clunking on takeoff or vibrations at low speeds. The GN-120 is engineered to meet the specific needs of Mercedes vehicles, providing reliability and performance in every drive.
