The MR-JE-200A+HG-SN152J-S100 is a Mitsubishi MR-JE-_A servo amplifier paired with an HG-SN152J-S100 AC servo motor, delivering 2.0 kW rated output at 2000 r/min. The motor includes an oil seal (J suffix), making it suited for applications where lubricant ingress is a concern — think gearboxes, spindles, or any rotary axis near oil mist.
The 2.0 kW output and 2000 r/min speed are the headline numbers, but the oil seal is the detail that decides fit in dirty environments. Without it, standard servo motors rely on labyrinth seals that pass fine oil mist over time. The J-spec seal keeps the bearing grease clean and the encoder free of contamination — a common failure point on machining centers and press feeders.
