SIRUBA 757H-516M2-35 — 5-Thread Overlock Industrial Sewing Machine

with Servo Motor and Fully Submerged

The SIRUBA 757H-516M2-35 is a high-performance 5-thread overlock (safety-stitch) industrial sewing machine designed for continuous production on light to medium fabrics. Delivered fully assembled with a direct-drive servo motor, submerged table, and stand, it provides quiet operation, precision, and energy efficiency — ideal for apparel factories, small production workshops, and fashion design studios.

General Applications

• Regular seaming on light to medium fabrics such as shirts, uniforms, and knitwear.
• Mock 516 safety stitching combining overedge and chain stitch for durable seams.
• Adaptable to five different sewing configurations by changing needle and looper combinations.

Key Features

• Patented High-Efficiency Direct-Drive System (700KD) — integrated motor within the machine frame for immediate response, low noise, and vibration-free performance.
• Built-in Servo Motor — quiet, energy-saving, and adjustable speed control.
• Built-in Synchronizer — smooth operation with free handwheel and needle positioning function.
• High-Efficiency Electrical System — compact, reliable, and energy-saving integrated electronics.

Sealed Direct-Drive Needle Bar Mechanism

• Fully sealed needle bar design prevents dust and oil leakage.
• Direct-drive system ensures high-speed performance and long durability.
• Eliminates drive loss typical of traditional connecting-rod needle bar systems.

Active Lubrication System

• Automatic oil supply with vacuum return system for the needle bar and upper looper.
• Outperforms traditional rope or drop-type lubrication methods.

Optional Equipment

• Built-in LED Lighting — patented, ergonomic design for precise visibility.

  • D201A (optional): 0.8 mm teeth spacing
  • D201B (optional): 1.0 mm teeth spacing
• Optional Presser Foot Fingers — short finger for heavy fabrics, long finger for light fabrics.

User-Friendly Adjustments

• Needle bar height adjustable without opening the machine.
• Fine-tuning mechanisms for lower looper and chainstitch length.
• Needle plate thread groove ensures perfect looping.
• 50 mm (5 cm) high sewing area for smoother fabric movement.

Patented Oil-Proof Feed Dog Mechanism

• Enhanced double-lip wiper system provides superior oil protection.
