Concentric Bore And OD Control Precision CNC Machined Spur Ring Gear CNC Turned Parts

Syris Precision CNC Machined Spur Ring Gear

Syris precision-manufactures this steel spur ring gear using precision gear hobbing/gear cutting combined with CNC turning and drilling, engineered for accurate torque transmission in geared drive assemblies.

Key Features:

• Precision-Cut Spur Teeth: Full circumference of accurately hobbed/shaped external gear teeth with consistent tooth profile, pitch, and root fillet geometry, ensuring smooth meshing and reliable load transfer with a mating pinion.
• Concentric Bore & OD: Precision-turned central bore and outer diameter, machined concentric to the pitch circle to minimize runout and ensure uniform gear engagement.
• Bolt-Circle Mounting Pattern: Evenly spaced, precisely drilled through-holes arranged in a symmetric bolt circle, enabling secure attachment to a mating hub, flange, or differential carrier.
• Stepped Web Design: Machined web section between the bore and gear rim, balancing weight reduction with structural rigidity to handle transmitted torque loads.
• Fine Machined Surface Finish: Bright, smooth surface finish across tooth flanks and mounting faces, reflecting tight process control critical for low-noise, low-wear gear meshing.
• Tight Dimensional Tolerances: Critical tooth spacing, bore concentricity, and bolt-hole positioning held to close tolerances for accurate, repeatable gear train performance.

Manufacturing Capabilities Demonstrated:

• Precision gear hobbing/cutting for spur tooth profiles
• CNC turning for concentric bore and OD control
• Bolt-circle drilling with tight positional accuracy
• Structural web machining for weight/strength optimization
• Fine surface finishing for gear meshing performance

Applications:
Well-suited for differential ring gears, gearbox drive components, industrial power transmission systems, or automotive final-drive assemblies requiring precise, high-torque gear engagement with secure hub mounting.
