Step 1: Pre-Installation Preparation
✔ Clean Environment: Work in ISO Class 8 (or cleaner) workspace
✔ Tool Checklist:
Precision torque wrench (0.1-5 Nm range)
Non-metallic drift punch
Cryogenic gloves (for cold mounting)
Dial indicator (for runout verification)

Step 2: Thermal Mounting (Recommended Method)
Heat Shaft: 80-100°C (176-212°F) for 30 mins
Caution: Never exceed 120°C (248°F)
Cool Bearing: -30°C (-22°F) for 15 mins (optional)
Quick Assembly: 10-second window for alignment

Step 3: Precision Alignment
Use 0.001mm resolution dial indicator to verify:
Radial runout <0.005mm
Axial wobble <0.003mm
Laser alignment recommended for <15mm bore sizes

Step 4: Torque Sequencing
Cross-Tighten mounting screws in 3 stages:
① 30% torque → ② 70% torque → ③ 100% torque
Pattern: Follow star sequence (see diagram)

Post-Installation Verification
✔ Rotation Test: Hand-spin should show:
Smooth motion (no stick-slip)
Uniform resistance (<0.05 Nm variation)
✔ Vibration Analysis: <0.5 mm/s RMS vibration
