Custom Brass Synchronizer Ring for Automotive Transmission Systems | Precision CNC Machined Baulk Ring
Description
Our custom Brass Synchronizer Rings, also widely known as Gearbox Baulk Rings or Synchro Rings, are high-precision CNC machined core components dedicated to automotive transmission systems, hybrid gearboxes, and heavy-duty engineering machinery drivetrains. Manufactured from premium copper alloy materials including phosphor bronze, brass and sintered bronze, this thin-wall slotted ring part is professionally engineered to solve gear shifting jitter, gear collision and poor synchronization problems, delivering stable, smooth and durable transmission performance for mechanical gearbox systems.
Strict precision control is implemented throughout the production process. The product achieves a tolerance of ±0.01mm, concentricity ≤0.02mm and surface roughness of Ra 0.8–1.6μm, with consistent tooth pitch and zero burrs on all tooth grooves. It perfectly solves the common processing pain points of thin-wall copper parts such as easy deformation, thermal stress and uneven slot precision, ensuring high matching accuracy and long-term operational stability.
We adopt a mature composite processing technology including CNC precision turning, gear shaping, broaching, micro slot milling and precision surface grinding. Combined with fine deburring and polishing treatment, the product fully meets the high-standard assembly requirements of original gearboxes. Custom heat treatment services are available to further enhance the surface hardness, wear resistance and fatigue resistance of the parts, adapting to high-frequency shifting and long-term heavy-duty working environments.
Widely applicable to automotive manual transmissions, hybrid electric vehicle transmission systems, heavy-duty truck gearboxes, construction machinery, agricultural machinery and industrial transmission equipment. It is a key wearable precision component for ensuring the smooth operation of power transmission systems.
