🛠️ How to Use / Installation Guide

🛠️ 1. Linear Bearings (LM12LUU)

• Slide onto 12mm hardened linear shaft.

• Insert into aluminum mounting blocks or 3D printer frame.

• Secure using clamping screws or set screws.

• Use with stepper motor + lead screw for X/Y motion.

🛠️ 2. Guide Blocks (HGH25CA, QHH20CA, etc.)

• Mount the guide rail to the machine frame using countersunk bolts.

• Align and install the linear guide block(s) on the rail.

• Attach your moving table or gantry to the top of the block.

• Ensure preload is correct to avoid unnecessary friction.

• Lubricate via grease ports or manual application for long-term use.

🔧 Optional accessories include grease nipples, dustproof end caps, and rail covers.
