Product Introduction – FUJIH4218K
Part Number: FUJIH4218K
Product Name: X-Axis Bearing
Applicable Model: Fuji NXT M6II Module
Category: Linear Motion Component
Description:
The FUJIH4218K is a high-precision X-axis linear bearing
specifically designed for the Fuji NXT M6II high-speed placement
module. It is responsible for guiding the moving head unit along
the X-axis with superior accuracy and stability during high-speed

This bearing is treated with a silver powder coating, which
enhances wear resistance, reduces friction, and improves overall
durability, making it suitable for long-term, high-load
applications in demanding SMT environments.
Key Features:
Precision-engineered for Fuji NXT M6II X-axis motion system
Silver powder surface coating for enhanced anti-wear and
anti-corrosion performance
Ensures smooth linear motion and accurate positioning
Supports high-speed, high-precision head travel
Long service life under continuous production conditions
Typical Applications:
X-axis movement of the placement head on Fuji NXT M6II
High-speed pick-and-place operations
Precision component placement lines in SMT production
Material & Coating:
Bearing body: Hardened steel
Surface treatment: Silver powder anti-friction coating
Compatibility:
Fully compatible with Fuji NXT M6II series X-axis rail systems
Works in conjunction with FUJIH4219A (Y-axis bearing) and
FUJIPM88765 (X-axis rail)

The silver powder coating provides enhanced wear resistance,
corrosion protection, and improved lubrication retention for longer
bearing life.
3. What are the signs of bearing failure?
Noisy or jerky X-axis movement
Increased vibration or friction
Reduced placement accuracy
Motor overload or abnormal feedback signals
4. How often should the bearing be replaced?
Typically recommended every 12–18 months depending on production
volume and operating conditions. Replace earlier if wear symptoms
appear.
5. Can I replace the bearing myself?
Replacement requires careful disassembly and alignment; it is
recommended to have trained maintenance personnel or Fuji
authorized service perform the procedure.
6. What tools are needed for replacement?
Hex wrenches (metric)
Torque driver
Linear guide alignment tools
Anti-static gloves
Cleanroom-grade lubricants compatible with silver coating
