Product Introduction
FUJI PM0CEG4 – NXT M3II X-Axis Gear
Overview
The FUJI PM0CEG4 is a high-precision X-axis drive gear used in the M3II modular unit of the FUJI NXT series SMT placement platform. This gear is part of the linear motion transmission system responsible for driving the head unit along the X-axis during component mounting operations.
Designed to withstand high-speed, repetitive motion and mechanical load, the gear ensures smooth, accurate, and stable movement of the head or gantry system.
Key Features
Precision Gear Machining
Manufactured with tight tolerances to ensure accurate positioning and repeatability in high-speed SMT operations.
Optimized for NXT M3II Modules
Specifically designed for integration with the M3II X-axis motor assembly and corresponding motion system.
Durable, High-Strength Material
Made from hardened alloy steel or treated aluminum, providing excellent resistance to wear and fatigue under continuous operation.
Reliable Rotary-to-Linear Motion Transfer
Works in combination with belt drives or ball-screw systems to convert motor torque into precise X-axis displacement.

FAQ Guide — FUJI PM0CEG4 NXT M3II X-Axis Gear
1. What is FUJI PM0CEG4?
Answer:
The PM0CEG4 is a precision-machined X-axis drive gear used in the FUJI NXT M3II module. It functions as a core component in the X-axis motion system, converting motor torque into mechanical movement to guide the placement head or gantry across the horizontal axis during high-speed SMT operations.
2. What is its function in the NXT M3II module?
Answer:
The PM0CEG4 gear:
Transmits power from the X-axis motor to the head unit
Enables smooth, accurate horizontal motion across the PCB
Works in coordination with the timing belt, pulley, and linear guides
3. Which machines use the PM0CEG4 gear?
Answer:
This gear is used in:
FUJI NXT M3II Modules
