LM10UU Extra Long Linear Ball Bearings, 10mm Bore, 19mm OD, 55mm Length, Sealed On Both Sides, Chromium Steel Ball Bearings, Smooth Low-Friction Glide, Built-Tough High-Precision Bushing For CNC And 3D Tools, Pack Of 4

LM10UU Pack of 4 Extra Long Linear Bearings for CNC
✔️ 10mm bore, 19mm OD, 55mm length; sealed on both sides

These LM10UU extra-long linear ball bearing bushings are designed for smooth, precise movement along guide rails and bars in CNC setups and 3D printers. With a 10 mm bore, 19 mm outer diameter, and 55 mm total length, these sealed-on-both-sides bearings provide reliable, low-friction performance in compact, heavy-use machines. Built from chromium steel, they resist wear and keep alignment under load, ideal for long-run guide blocks and linear stages.

✅ 10 mm bore, 19 mm outer diameter, 55 mm length
✅ Sealed on both sides for dust protection
✅ Chromium steel shell and bearing balls for high wear resistance
✅ Smooth, low-friction glide with high rigidity
✅ Pack of 4 for multiple axes and spares

💡 What is a linear ball bearing used for in precision motion equipment? This handy component keeps X/Y axes aligned and ensures smooth travel in CNC machines and 3D printers.

- supports precise linear motion on CNC routers and 3D printers - reduces wear on guide rails and maintains alignment - sealed design minimizes dust intrusion and maintenance - chromium steel construction handles load with rigidity
