Precision CNC Machined Motor Flange Housing – Syris Manufacturing

Product Overview

This precision CNC-machined component, produced by Syris, is a round aluminum flange housing featuring a stepped conical bore, a six-hole bolt pattern, and a bright, precisely turned surface finish. The concentric, tapered profile reflects Syris's capability in producing rotationally accurate flange components for motor or drivetrain interfaces.

Key Features

• Stepped Conical Bore — A smoothly tapered, multi-diameter center bore transitions through several precisely turned steps, designed to seat a motor shaft, bearing, or coupling with accurate axial positioning.
• Six-Hole Bolt Circle — An evenly spaced pattern of six precision-bored mounting holes around the flange perimeter provides secure, accurately aligned attachment to a mating motor or gearbox housing.
• Tight Concentricity Control — All turned diameters share a common rotational axis, critical for maintaining shaft alignment and minimizing runout in rotating assemblies.
• Tapered Conical Profile — The gently sloped outer face reduces material while maintaining structural stiffness, and aids in directing airflow or cabling around the flange.
• Precision Turned Finish — A smooth, reflective surface across all diameters indicates tight-tolerance lathe work suitable for sealing or bearing-seat surfaces.
• Compact Flange Footprint — The round, evenly proportioned design allows for a space-efficient interface between two rotating or stationary assemblies.

Applications

Suited for electric motor end bell flanges, gearbox input/output flanges, pump or actuator mounting interfaces, and other rotating machinery applications requiring precise concentric bore alignment and bolt-pattern accuracy.

Manufacturing Capability

This part demonstrates Syris's capability in precision turn-mill machining — combining accurate lathe turning of stepped bores with precise bolt-hole drilling to produce concentric, rotation-ready flange components for motor and drivetrain applications.
