POM Wheel with 625ZZ Linear Bearing

POM Wheel with 625ZZ Linear Bearing – 3D Printer Pulley for Ender-3, CR-10 & Laser Engraver (Multiple Variants)

The POM Wheel with 625ZZ Linear Bearing is a precision motion component designed for 3D printers, CNC machines, and laser engravers that use V-slot aluminum extrusion rails. Made from durable POM (Polyoxymethylene) engineering plastic, these wheels provide smooth movement, low friction, and quiet operation, helping improve printing accuracy and machine stability.

Each wheel comes equipped with a 625ZZ double-shielded ball bearing, ensuring reliable rotation and long service life while protecting the bearing from dust and debris. These wheels are widely used as replacement or upgrade parts for popular 3D printers like the Ender-3, Ender-3 Pro, Ender-3 V2, and CR-10 series, as well as other V-slot based motion systems.

This product is available in multiple variants, allowing you to select the correct wheel type for different axes and motion systems in your machine.

Available Variants

Big Wheel
A larger POM wheel designed for motion systems that require increased stability and support. Ideal for heavy components or larger machine frames.

V Wheel
Standard V-slot wheel designed to run smoothly along V-slot aluminum extrusion rails. This is the most common wheel used in Ender-3 and CR-10 printers.

White Small Wheel
A compact white POM wheel suitable for smaller assemblies, lightweight components, and precision movement in CNC and laser engraving systems.
