POM V-Slot Idler Pulley Wheel with Bearing | 3D Printer
POM V-Slot Idler Pulley Wheel with Bearing | 3D Printer
Upgrade your 3D printer's motion system with these precision-machined POM (Delrin) V-Slot Idler Pulley Wheels. Available in Big Wheel, V Wheel, and Small Wheel configurations, these pulleys are CNC-machined on a high-precision automatic lathe to a machining error within 0.005mm — ensuring ultra-smooth, consistent movement along your aluminum extrusion rails.
Whether you're running a Creality Ender 3 V2, CR-10, CR-10S, Tevo Tarantula, or a CNC router hybrid system, these wheels are a direct-fit upgrade for improved print quality and reliability. The motor-grade 625ZZ and MR105ZZ bearings are rust-resistant and wear-resistant, delivering low-noise, low-friction operation even at higher print speeds.
Made in Mainland China.

Frequently Asked Questions
Q: Are these POM V-slot pulley wheels compatible with the Creality Ender 3 V2?
A: Yes! These POM idler pulley wheels are specifically designed to be compatible with the Creality Ender 3, Ender 3 V2, Ender 3 Pro, and similar V-slot aluminum extrusion-based 3D printers. They are a direct replacement or upgrade for the stock wheels on most Creality machines.
Q: What is the difference between the Big Wheel, V Wheel, and Small Wheel?
A: The Big Wheel (24.2mm OD, 625ZZ bearing) and V Wheel (24.8mm OD, 625ZZ bearing) are both used on standard V-slot aluminum profile rails for the X, Y, and Z axis carriages. The Small Wheel (15.5mm OD, MR105ZZ bearing) is a compact idler used in tighter spaces or specific carriage configurations. Select the variant that matches your printer's specifications.
Q: What bearing type do these pulley wheels use?
A: The Big Wheel and V Wheel use 625ZZ motor-grade bearings, while the Small Wheel uses MR105ZZ bearings. Both are shielded, rust-resistant, and wear-resistant for long-lasting, low-noise performance.
Q: Will upgrading to these POM pulleys improve my print quality?
A: Absolutely. Worn or poorly made wheels introduce vibration and inconsistency in carriage movement, which shows up as print artefacts like ringing or layer inconsistency. These precision CNC-machined pulleys with motor-grade bearings deliver smoother, more accurate axis movement — helping your printer achieve higher speeds with better dimensional accuracy.
