12Pcs Lm4Uu Linear Ball 12-pack built for smooth installs and solid results
✔️ 12pcs LM4UU Linear Ball Bearings, 4mm Bore Dia, 8mm OD,12mm Length, Linear Motion Bearing for CNC Machine

This 12 pack is meant for clean replacement or upgrade work where fit and smooth operation matter.

✅ Package Included: 12pcs Metric Double Seal Linear Bearing
✅ Model: LM4UU, Bore Diameter (dr): 4mm, Outer Diameter (D): 8mm, Total Length (L): 12mm. Static Load Capacity (Cor): 88.2N, Dynamic Load Capacity (Cr): 108N
✅ Quality Material: The linear bearing is made of bearing steel, which has good abrasion resistance, high precision, and good strength, plated surface treatment can operate under high-temperature conditions.
✅ Design - Linear bearings allow low noise, smooth movement, low friction, high rigidity, and long service life. Designed with two rubber dust sealed to prevent dirt, water, or other items from ingress.
✅ High Precision - Rely on precise dimensions and manufacturing processes, the linear bearings support highly consistent motion control. They maintain stable linear motion while reducing friction and vibration, allowing for higher precision requirements.

💡 What lubrication setup helps a ballscrew run smoother at higher speeds?
Quick answer: match pitch, travel length, and support style to your axis load and speed.
* Pitch controls feed rate and torque demand
* Proper end supports keep alignment tight under load
* Good lubrication cuts heat and wear over time

Built to keep motion smooth and accuracy steady during long production runs.
