5mm Aluminium Round Spacer

Unthreaded cylindrical aluminium sleeves with 5.1mm bore for M5 clearance fit and 10mm outer diameter. Designed for component spacing in mechanical assemblies requiring a larger footprint and higher rigidity than standard 3mm spacers.

• All dimensions in mm, tolerance +/- 0.01 mm. Additional dimensions available on request.

Benefits #

5mm aluminium round spacers address the need for stable, lightweight component separation in heavier mechanical assemblies. The 10mm outer diameter provides a wider bearing surface than 3mm variants, distributing load more evenly and reducing point stress on mounting surfaces. In CNC gantries and motor mounts, insufficient spacing leads to vibration, misalignment, and premature bearing wear. These spacers maintain exact clearances between structural plates and moving components. The smooth M5 bore accepts standard bolts without thread engagement, allowing rapid assembly and teardown. Aluminium’s corrosion resistance and non-magnetic properties make these spacers suitable for outdoor robotics and electronics-adjacent installations.

Common Applications #

Suited for structural spacing in medium-duty mechanical and industrial assemblies.

• CNC machine gantry spacing
• 3D printer frame spacing
• Robotics structural spacing
• V-slot linear rail spacing (40-series)
• Motor mount spacing
• Belt tensioner spacing
• Industrial machinery spacing
• Heavy-duty prototype projects
