OpenBuilds Eccentric Spacer for V-Wheels (5mm Bore)

Product Description

The Eccentric Spacer 5mm is an indispensable piece of hardware designed to bring absolute precision to your linear motion systems. When building or maintaining high-performance FDM 3D printers, custom CNC routers, or laser engraving machines, achieving the perfect amount of tension between your V-wheels and the aluminum extrusion is critical. This eccentric column allows you to dial in exactly that tension with a simple turn of a wrench.

Manufactured from highly durable metal to withstand constant mechanical vibration, this spacer features a specialized off-center 5mm bore. As you rotate the spacer, it physically moves the V-wheel closer to or further from the V-slot rail, effectively locking your gantry in place and completely eliminating carriage wobble or unwanted play.

Whether you are assembling a new Z-axis, upgrading an OpenBuilds gantry, or simply performing routine maintenance on your workshop equipment, these eccentric spacers are vital for maintaining the structural rigidity, smooth travel, and ultimate accuracy of your moving parts.

Key Features

• Adjustable tension: Off-center 5mm bore allows for precise tuning of V-wheel grip against aluminum extrusions.

• Standard sizing: Perfectly matches standard M5 bolts and OpenBuilds V-wheel hardware.

• Wobble elimination: Secures linear carriages tightly, removing unwanted play and mechanical vibration.

• Durable construction: Built to resist crushing and wear under the high loads of heavy CNC gantries.

• Easy installation: Features a standard 8mm hex profile for quick, accessible adjustments using a simple wrench.

Applications

• Fine-tuning V-wheel tension on the X, Y, and Z axes of custom 3D printers

• Securing linear motion gantries on heavy-duty CNC routers and milling machines

• Eliminating carriage play in high-speed laser engraving equipment

• Adjusting sliding camera mounts and automated moving tracks for electronics
