Precision CNC Machined Dual-Bore Gearbox Plate – Syris Manufacturing

Product Overview

This precision CNC-machined component, produced by Syris, is a bright-finished aluminum plate featuring two large stepped bearing bores, a central smaller bore, and dense bolt-circle hole patterns surrounding each opening. The layered, gear-housing-style geometry reflects Syris's capability in producing multi-bore transmission or gearbox plates with tight concentricity across several precision-turned features.

Key Features

• Dual Large Stepped Bores — Two precisely turned stepped bores, each with concentric shoulder steps, are sized to seat bearings, seals, or shaft journals with accurate axial positioning.
• Central Auxiliary Bore — A smaller precision-bored center hole between the two main bores accommodates an additional shaft, idler, or pilot feature.
• Dense Bolt-Circle Patterns — Multiple evenly spaced bolt circles surround each bore, providing secure, accurately aligned attachment points for bearing retainers or mating housings.
• Contoured Hourglass Profile — A waisted outer silhouette connects the upper and lower bore sections, reducing material while maintaining structural rigidity between the two mounting zones.
• Decorative Milled Accents — Fine radial line detailing machined into the waist section adds a refined surface texture beyond purely functional requirements.
• Bright Machined Aluminum Finish — A clean, reflective surface finish throughout demonstrates precise face turning and milling with tight surface-quality control.

Applications

Suited for transmission or gearbox end plates, differential housings, dual-shaft mounting plates, and other drivetrain applications requiring precise concentric bore alignment across multiple rotating axes.

Manufacturing Capability

This part demonstrates Syris's capability in complex turn-mill machining — combining multiple concentric bore turning operations, dense bolt-hole drilling, and contoured profile milling to produce drivetrain-grade plates with tight positional and concentricity tolerances.
