3D Printer Lithium Grease – Lead Screws, Linear Rails & CNC

Professional-Grade 3D Printer Lubricant for Smoother, Quieter Prints

Keep your 3D printer running at peak performance with this high-speed lithium grease, specially formulated for lead screws, linear rails, bearings, and pulleys. Whether you're running a Creality Ender, Bambu Lab, Prusa, Anycubic, Voron, or any other FDM printer, this lubricant delivers long-lasting protection, reduced noise, and ultra-smooth motion — every single print.

Made in Mainland China.

Why This Lubricant Stands Out

• 🤖 Precise & Smooth Movement: Low-resistance formula minimises drag on guide screws, improving surface quality and dimensional accuracy of every printed model.
• 🔥 High-Temperature Stability: Drop point exceeds 250 °C — even near the hot end, this grease keeps lubricating without flowing off or evaporating.
• 🛡️ Plastic & Rubber Safe: Fully synthetic base oil is completely compatible with plastics and rubber, so critical printer components stay protected — never corroded.
• ⏳ Ultra-Long Service Life: Outstanding oxidation resistance and low oil separation means one application goes the distance, significantly reducing how often you need to re-lubricate.
• 🔇 Quieter Operation: Dramatically cuts mechanical noise from rails and screws, creating a quieter printing environment.

🔧 How to Apply — Step-by-Step

1. Clean First: Wipe down the guide rail or screw thoroughly with isopropyl (anhydrous) alcohol and a lint-free cloth to remove old grease and dust.
2. Apply Sparingly: Dab a small amount of grease onto the linear rail surface or screw threads. A thin, even layer is all you need — less is more.
3. Distribute Evenly: Manually move the print head or Z-axis through its full range of motion several times to spread the grease uniformly.
4. Wipe Excess: Use a clean cloth to remove any excess grease from exposed surfaces.

Compatible With

All major 3D printer brands including Creality, Ender series, Bambu Lab, Prusa, Anycubic, Voron, and virtually any FDM/CoreXY printer with linear rails or lead screws. Also ideal for CNC machines and other precision motion systems.

Frequently Asked Questions

Q: Is this lithium grease safe to use on the plastic and rubber parts of my 3D printer?

A: Yes! This lubricant uses a fully synthetic base oil that is completely compatible with both plastics and rubber. It will not corrode, swell, or degrade the plastic carriages, rubber belts, or seals found in most 3D printers — making it safe for all key printer components.

Q: How often do I need to reapply this grease to my lead screws and linear rails?

A: Thanks to its excellent oxidation resistance and low oil-separation properties, a single application lasts significantly longer than standard greases. For most home 3D printers under regular use, reapplication every 3–6 months (or as part of a seasonal maintenance routine) is typically sufficient — though heavily used or high-speed machines may benefit from more frequent checks.

Q: Can this lubricant be used on CNC machines as well as 3D printers?

A: Absolutely. This high-speed lithium grease is formulated for precision motion systems, making it equally well-suited to CNC router rails, ball screws, and bearings in addition to 3D printer components.

Q: What temperature range does this grease handle?

A: The grease is rated for continuous use between -20 °C and 120 °C, with a drop point exceeding 250 °C. This means it stays in place and continues lubricating even in close proximity to the heated bed or hot end of your 3D printer without melting or running off.
