Description

This CNC machined ARRI Rosette gear disc, also known as a face serration plate or Hirth coupling component, is a high-precision mechanical part designed for reliable angular positioning and secure locking applications. Manufactured from high-quality aluminum or stainless steel using advanced CNC milling and turning processes, it ensures excellent dimensional accuracy, durability, and repeatability.

The radial serration structure on the contact surface allows two mating discs to interlock firmly under axial clamping force, providing a zero-backlash connection and strong torque transmission without slippage. This design makes it ideal for applications requiring frequent angle adjustment combined with stable positioning performance.

Widely used in camera rigs, gimbal systems, robotic joints, and industrial automation equipment, this component offers both flexibility and rigidity in mechanical assembly. Surface treatments such as anodizing, sandblasting, or polishing further enhance corrosion resistance and aesthetic quality.

Custom designs are fully supported, including tooth count, diameter, mounting hole patterns, and tolerance requirements, making it suitable for both prototyping and mass production.
