OpenBuilds POM V-Wheel Linear Bearing (5mm Bore)

Product Description The POM V-Wheel 5mm is a high-performance linear motion wheel designed to deliver extremely smooth and precise travel along V-slot aluminum extrusions. Engineered for high-precision machinery, it serves as the perfect idler or drive wheel for modern FDM 3D printers, custom CNC routers, and heavy-duty laser engraving systems.

Manufactured from highly durable Polycarbonate and POM materials, this V-wheel provides exceptional wear resistance and structural rigidity, minimizing compression under heavy mechanical loads. The integrated 5mm bore bearing guarantees incredibly low friction, ensuring your motion systems remain highly accurate and whisper-quiet even during high-speed operations.

Whether you are upgrading an existing X-axis gantry or building a custom linear motion actuator from scratch, this V-wheel is built to withstand the rigorous demands of a busy workshop. It fits seamlessly into standard OpenBuilds hardware ecosystems for quick and highly reliable installation.

Key Features

• Smooth linear motion: Low-friction integrated bearings provide precise, stutter-free movement along aluminum extrusions.

• Durable material: Crafted from wear-resistant Polycarbonate/POM to handle continuous mechanical stress without deforming.

• Standard sizing: Features a precision 5mm bore, perfectly matching standard M5 hardware and mounting plates.

• High load capacity: Resists compression and maintains perfect roundness even on heavy CNC and laser gantries.

• Quiet operation: Significantly minimizes mechanical vibration and noise during high-speed travel.
