LM3UU Linear Bearing 3mm Bore 7mm OD 10mm Length Dual Rubber Sealed Ball Bearings For CNC Machines And 3D Printers Dustproof Smooth Glide Low Friction Durable Steel Construction

Single LM3UU Linear Bearing: 3mm Bore, 7mm OD, 10mm Length
✔️ 3 mm bore, 7 mm OD, 10 mm length, dual rubber seals

This LM3UU linear bearing is a compact, sealed ball bearing designed for precision motion in CNC machines and 3D printers. It rides on cylindrical shafts in linear slide unit assemblies to deliver smooth, low-friction travel.

✅ Dual rubber seals for dustproof operation (2 seals)
✅ 3 mm bore (0.12 in), 7 mm OD (0.28 in), 10 mm length (0.39 in)
✅ Steel construction for rigidity and durability
✅ Smooth motion with low friction and high accuracy
✅ Suitable for cylindrical shafts or guideways in precision equipment
