Precision CNC Machined Ring Gear – Syris Manufacturing

Product Overview

This precision CNC-machined ring gear, produced by Syris, is a large-diameter external spur gear featuring fine, evenly spaced gear teeth around its full circumference and a multi-hole mounting flange. The two-tone finish — a black-oxide treated tooth face paired with a bright, polished metal flange — highlights both the functional gearing surface and the precision-machined mounting interface.

Key Features

• Precision Gear Teeth — A full ring of accurately machined spur gear teeth ensures smooth, consistent meshing and reliable power transmission with minimal backlash.
• Black Oxide Tooth Finish — The gear face is treated with a black oxide coating, providing improved wear resistance, mild corrosion protection, and reduced friction during operation.
• Bright Machined Flange — The mounting flange retains a clean, polished metal finish, offering a precise reference surface and a visually distinct contrast to the treated gear teeth.
• Multi-Bolt Hole Pattern — An evenly spaced circular array of precision-bored mounting holes allows secure, accurate alignment with mating drivetrain or gearbox components.
• Large Open Bore — A wide central bore accommodates shafts, hubs, or differential housings typical of automotive or heavy machinery drivetrain assemblies.
• Tight Dimensional Control — CNC gear cutting and turning processes ensure consistent tooth profile, pitch accuracy, and concentricity critical to smooth rotational performance.

Applications

Suited for automotive differential ring gears, transmission and gearbox components, industrial power transmission systems, and other rotating machinery requiring precise gear meshing and durable wear performance.

Manufacturing Capability

This part demonstrates Syris's capability in precision gear machining — combining accurate CNC gear cutting, hole drilling, and surface treatment (black oxide finishing) to deliver drivetrain-grade components with reliable performance from prototype through full production runs.
