Mellow VORON 2.4 R2 Motion Kit – Gates GT2 Belts, Pulleys & Bearings
Mellow VORON 2.4 R2 Complete Motion Kit – Gates GT2 Timing Belts, Aluminum Pulleys, Idlers & Bearings
Upgrade your VORON 2.4 R1/R2 build with this comprehensive motion kit from Mellow. Engineered for precision-driven 3D printing, every component is selected to work in perfect harmony — from genuine Gates GT2 synchronous belts to CNC-machined aluminum alloy pulleys and P6-grade sealed bearings. Whether you're building from scratch or refreshing your drivetrain, this kit delivers the consistency and accuracy that demanding prints require.
Why Choose This Motion Kit?
- Genuine Gates GT2 Belts: Manufactured using Gates-supplied tooling and tooth profiles. The neoprene rubber / fiberglass-core construction minimizes stretch and vibration, keeping your motion system tight and repeatable.
- Precision-Tooled Pulleys: Mellow's 16T, 20T, and 80T pulleys are produced with specialized Gates-compatible tooling, achieving tighter tolerances than standard pulleys to eliminate belt skip and improve layer consistency.
- Toothed & Smooth Idlers: Toothed idlers gently cradle belt teeth through every curve, preventing wear. Smooth idlers are flanged and correctly sized to maintain constant belt tension across the full stroke.
- P6-Grade Bearings: F695 2RS and 625 2RS double-sealed bearings rated to P6 precision ensure smooth, low-noise rotation and long service life.
- Ground-Flat Steel Shafts: Included 5mm shafts with precision ground flats ensure secure, wobble-free pulley seating.
- Complete Compatibility: Designed specifically for VORON 2.4 R1 and R2 — no guesswork, no sourcing individual parts from multiple vendors.

Frequently Asked Questions
Q: Is this Mellow VORON 2.4 motion kit compatible with both R1 and R2 versions?
A: Yes. The Mellow GT2 motion kit is designed to be fully compatible with both the VORON 2.4 R1 and VORON 2.4 R2 builds. All pulleys, idlers, belts, shafts, and bearings are sized and specified to match the official VORON 2.4 BOM requirements.
Q: Are the timing belts in this kit genuine Gates belts?
A: Yes. The open GT2 belts (LL-2GT-6 and LL-2GT-9) and the 188-2GT-6 closed-loop belts are all genuine Gates brand products, manufactured to Gates specifications for accurate tooth profile, minimal stretch, and low vibration during operation.
Q: What bearing grade are the F695 and 625 bearings included in this kit?
A: Both the F695 2RS and 625 2RS bearings are P6 precision grade and double-sealed (2RS), providing smooth rotation, reduced noise, and protection against dust and debris — important for maintaining consistent motion performance in an enclosed 3D printer environment.
Q: Do the pulleys require any special tools or hardware to install?
A: Assembly is required. The pulleys are secured using 2× M4 set screws (included) onto 5 mm bores. Standard hex keys are sufficient for installation. The included ground-flat shafts ensure a secure, wobble-free fit when the set screws are tightened against the flat.
