Our company has been in operation for 11 years and will definitely be your best choice with guaranteed quality and fast delivery





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 operations.
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)
