Precision CNC Machined Bridge-Frame Motor Mount

Syris Precision CNC Machined Bridge-Frame Motor Mount

Syris precision-manufactures this aluminum bridge-frame bracket using multi-axis CNC machining, featuring an open box architecture with co-axial precision bores engineered for motor, gearbox, or shaft-mounted assembly integration.

Key Features:

• Open Bridge-Box Structure: Precision-milled U-shaped frame with an arched top bridge span, providing internal clearance for a motor body, gearbox, or coupling while maintaining rigid structural support at all four corners.
• Aligned Precision Bores: Large, accurately bored holes on both the front and internal wall faces, machined to ensure precise coaxial alignment for shaft passage or bearing seating.
• Dense Threaded Hole Pattern: Extensive array of precisely tapped mounting holes across the top bridge, side walls, and base flanges, supporting flexible multi-point attachment for covers, sensors, or adjoining components.
• Extended Side Legs: Tall, parallel side walls extending downward from the bridge, providing elevated clearance and a stable multi-point base footprint for mounting to a larger platform.
• Reinforced Corner Transitions: Smoothly filleted internal corners at bridge-to-wall junctions, reducing stress concentration and enhancing overall structural rigidity.
• Fine Machined Surface Finish: Bright, consistent surface finish throughout, reflecting tight process control and dimensional accuracy across all bore and mounting features.

Manufacturing Capabilities Demonstrated:

• Multi-axis CNC milling of complex open bridge-frame geometry
• Precision co-axial boring across separated wall sections
• Dense multi-plane hole tapping
• Structural fillet and transition machining
• Tight positional tolerance for shaft/motor alignment

Applications:
Well-suited for motor/gearbox mounting frames, robotic joint housings, actuator support structures, or industrial automation sub-assemblies requiring precise shaft alignment combined with a rigid, elevated mounting platform.
