LM8UU 8mm Linear Motion Bearing for 3D Printer
High-precision LM8UU linear ball bearing designed for smooth, low-friction linear motion on 8mm shafts. Essential for 3D printers, CNC machines, and precision automation projects. Available from The Engineer Store, Bengaluru with fast shipping and reliable support.
Specifications
| Bearing Model | LM8UU |
| Type | Closed Linear Ball Bearing |
| Inner Diameter (Bore) | 8 mm |
| Outer Diameter | 15 mm |
| Length | 24 mm |
| Ball Rows | 4 rows of recirculating steel balls |
| Dynamic Load Rating | ~196 N (typical) |
| Static Load Rating | ~78 N (typical) |
| Material (Outer Casing) | Carbon steel with corrosion-resistant plating |
| Ball Material | Chrome steel (GCr15) |
| Seal Type | Rubber seals on both ends |
| Compatible Shaft Diameter | 8 mm hardened & ground smooth rod |
| Lubrication | Pre-lubricated with grease |
| Operating Temperature | -20 degreesC to +80 degreesC |
| Tolerance | Standard clearance fit on 8 mm h6/h7 shafts |
| Origin | Original / Authentic |
| Warranty | 7-day warranty on manufacturing defects |
| Support | Email & WhatsApp 24/7 |
Key Features
- Precision Ground Construction: Tight tolerances ensure wobble-free, accurate linear travel along 8mm smooth rods
- 4-Row Ball Circuit Design: Recirculating steel balls distribute load evenly for consistent, ultra-smooth motion
- Dual Rubber Seals: Keeps dust, debris, and filament particles out while retaining internal lubrication for extended life
- Pre-Lubricated & Ready to Install: Factory-greased for immediate use - no additional lubrication needed out of the box
- Low Friction Coefficient: Minimal resistance allows stepper motors to operate efficiently with reduced current draw and heat
- Compact 15mm Outer Diameter: Standard dimensions fit directly into common 3D printer bearing mounts and CNC carriages
- Corrosion-Resistant Plating: Durable outer shell withstands humid workshop environments without rusting
- Self-Aligning Capability: Minor shaft misalignment is absorbed without binding, improving reliability in DIY builds
Why Choose This?
- 100% authentic bearing from trusted manufacturing suppliers - no low-grade clones
- Industry-standard LM8UU dimensions ensure drop-in compatibility with Prusa i3, Anet A8, CR-10, and most RepRap-style 3D printers
- 1-5 day shipping, 7-8 day delivery across India from our Bengaluru warehouse
- Expert technical support to help with installation, alignment, and troubleshooting
- Ideal upgrade from worn or noisy stock bearings to restore print quality
Project Ideas
- 3D Printer Axes: Use on X, Y, and Z axes of RepRap, Prusa i3, Anet A8, and similar printers for smooth carriage and bed movement
- DIY CNC Router/Engraver: Mount on 8mm guide rods for precise linear travel of the spindle or work table
- Laser Cutter/Engraver Gantry: Provide low-friction motion for the laser head assembly on smooth rod rails
- Camera Slider: Build a motorized or manual camera slider for cinematic video panning shots
- Linear Actuator Projects: Combine with lead screws and stepper motors for precision positioning systems and automation
- Robotics & Pick-and-Place: Enable smooth linear motion in robotic arms, dispensing systems, and conveyor mechanisms
- Educational Kits: Teach students about linear motion, friction, mechanical design, and CNC fundamentals
Compatibility & Usage Notes
- Designed exclusively for use with 8mm hardened and ground smooth rods (h6 or h7 tolerance recommended)
- Not suitable for use on threaded rods, hollow tubes, or unhardened shafts - these will cause premature wear
- Standard press-fit into bearing holders; secure with zip ties, printed clamps, or dedicated aluminum mounts
- For best results, ensure rods are parallel and properly aligned to prevent binding
- Re-lubricate with light machine oil or white
