OpenBuilds POM Plastic Mini V-Wheel Heavy Duty Delrin Linear Guide Wheel for CNC & 3D Printers

Overview

Engineering high-precision linear motion requires ultra-smooth rolling components. Our OpenBuilds POM Plastic Mini V-Wheels are precision CNC-machined from solid Delrin (Polyoxymethylene) engineering plastic. Unlike cheap molded wheels that suffer from uneven surfaces and flat spots, these machined V-wheels deliver flawless, silent tracking along standard V-Slot aluminum extrusions. Their compact design makes them ideal for space-constrained applications like compact 3D printer carriages, laser engravers, and smooth camera sliders.

Key Features

• Precision CNC Machined: Crafted from high-density POM plastic for perfectly concentric geometry, eliminating axis jitter and banding in 3D prints.

• High Wear Resistance: Delrin possesses natural self-lubricating properties, resisting friction-induced wear and material degradation over long operational hours.

• Ultra-Quiet Operation: Absorbs vibrations much better than metal bearings, providing a near-silent linear guide system.

• Dual Bearing Pocket: Features internal precision steps designed to seat two standard MR105ZZ bearings (5mm bore) perfectly centered.

• Compact Footprint: Specifically engineered to ride smoothly inside the narrow channels of 2020, 2040, or 2080 V-Slot profile rails.

Technical Specifications

Whats the difference between Mini V-Wheels and Solid V-Wheels?

• Mini V-Wheel: Features a smaller outer diameter (15.23mm). It is meant to guide a carriage more compactly or ride inside specific low-profile configurations.

• Solid/Dual V-Wheel: Larger diameter (24.39mm). Designed for heavy-duty load carriage on larger CNC platforms like the WorkBee or Ox CNC.
