Mellow LML6UU Linear Ball Bearing 6x12x35mm – 2-Pack
Mellow MYT Bearing LML6UU – High Precision Long Linear Ball Bearing (2-Pack)
Upgrade your 3D printer's motion system with the Mellow MYT LML6UU Long Linear Ball Bearing. Engineered to tight tolerances with a nickel-plated finish, this 6x12x35mm bushing delivers ultra-smooth, linear travel with minimal play — helping your printer produce sharper, more accurate models print after print.
Why Choose Mellow MYT LML6UU Bearings?
- High Precision, Tight Tolerances: Manufactured to close dimensional specs (ID: 6mm / OD: 12mm / Length: 35mm) for consistent, repeatable motion.
- Vibration-Free Travel: Smooth ball-track design dramatically reduces jitter and wobble during fast print moves, preserving fine surface detail.
- Nickel-Plated Finish: Corrosion-resistant surface treatment extends service life in demanding workshop environments.
- No Assembly Required: Drop-in replacement — ready to install straight out of the pack.
- Compatible with Ultimaker 2 & More: Fits any 3D printer or CNC axis that accepts standard LM6LUU / LML6UU linear bushings.
- 2 Pcs Per Pack: Great value — stock up for a full axis replacement or keep spares on hand.

Frequently Asked Questions
Q: What printers are compatible with the Mellow LML6UU linear ball bearing?
A: The LML6UU bearing is compatible with any 3D printer or motion system that uses a 6mm linear rod and accepts the standard LM6LUU / LML6UU bushing format. This includes the Ultimaker 2, Ultimaker 2+, many RepRap variants, Prusa-style machines, and DIY CNC builds with 6mm guide rods.
Q: What is the difference between LM6UU and LML6UU bearings?
A: The LML6UU (also written LM6LUU) is the "long" version of the LM6UU bearing. While both share the same 6mm inner diameter and 12mm outer diameter, the LML6UU has a longer body (35mm vs. ~19mm) which provides greater contact surface, resulting in smoother, more stable linear motion — ideal for longer travel axes on 3D printers and CNC equipment.
Q: How many bearings come in one order?
A: Each pack includes 2 pieces of the Mellow MYT LML6UU long linear ball bearing, ready to install with no additional assembly required.
Q: What does the nickel-plated finish do?
A: The nickel-plated surface treatment provides a corrosion-resistant barrier, helping the bearings maintain smooth performance over time even in environments with humidity or temperature variation — common in enclosed printer enclosures and workshop settings.
