POM V-Slot Idler Pulley Wheel with Bearing for 3D Printer
POM V-Slot Idler Pulley Wheel with Bearing for 3D Printer
POM V-Slot Idler Pulley Wheels with Bearing – Precision CNC Machined for 3D Printers
Upgrade your 3D printer's motion system with these high-precision CNC-machined POM (Delrin) idler pulley wheels. Engineered to fit V-slot aluminum extrusion profiles, these wheels deliver smooth, low-noise movement and improved print accuracy — making them an ideal replacement or upgrade part for Ender 3, Ender 3 V2, CR-10, CR-10S, Tevo Tarantula, CNC router hybrids, 8020, 3030 frames, and more.
Made in Mainland China.
Why Choose These Pulley Wheels?
- Ultra-Precise Machining: Produced on high-precision automatic lathes with a machining error of within 0.005mm for consistent, repeatable motion.
- Motor-Grade Bearings: Fitted with motor-grade 625ZZ or MR105ZZ bearings that are rust-resistant, wear-resistant, and operate with excellent low-friction smoothness.
- Smooth & Quiet Operation: Engineered for minimal noise, smoother axis travel, and higher printing speeds without sacrificing accuracy.
- POM/Delrin Material: Durable, self-lubricating plastic that glides effortlessly along V-slot aluminum profiles and resists wear over time.
- Wide Compatibility: Fits popular 3D printer frames and CNC machines that use standard V-slot extrusion profiles.

Frequently Asked Questions
Q: Are these POM pulley wheels compatible with Creality Ender 3 and Ender 3 V2 printers?
A: Yes! These CNC-machined POM V-slot idler pulley wheels are fully compatible with the Creality Ender 3, Ender 3 V2, CR-10, CR-10S, and many other 3D printers that use standard V-slot aluminum extrusion profiles. Always double-check your frame's slot dimensions before ordering.
Q: What type of bearings are used in these pulley wheels?
A: The big wheel and V-wheel use motor-grade 625ZZ shielded bearings, while the small wheel uses MR105ZZ bearings. Both bearing types are rust-resistant, wear-resistant, and designed for smooth, long-lasting performance.
Q: Do I need to assemble the pulley wheels, or do they come pre-assembled?
A: The bearings are pre-installed in the POM wheel bodies, but some assembly is required when mounting them onto your printer's carriage or frame hardware (such as bolts, spacers, and nuts sold separately).
Q: Will these wheels reduce noise on my 3D printer?
A: Yes. The precision-machined POM/Delrin material combined with motor-grade shielded bearings promotes smooth, low-noise axis travel, which can noticeably reduce operational noise compared to worn or lower-quality wheels.
