This advanced sewing machine is equipped with a double straight needle system combined with a vertical automatic self-lubricating hook. The sliding rods are designed to guide the thread, creating a two-line double-thread lockstitch pattern. This ensures a strong and even stitch that's ideal for heavy-duty applications.
The needle bar features a mechanical separation and connection mechanism, offering smooth and reliable performance. The vertical axis utilizes ball bearings for smooth rotation and is driven by a synchronized toothed belt, ensuring precise and consistent movement during operation.
A plunger-type oil pump lubrication system is integrated to maintain optimal performance and extend the life of the machine. The feeding mechanism synchronizes with the needle bar using a feeding tooth system, allowing for accurate and stable fabric feeding. The knob-style disc adjustment allows for easy needle position control, while the release lever feed mechanism ensures smooth and controlled movement.
The shuttle mechanism incorporates a spring-loaded tension system, which helps maintain consistent thread tension, resulting in uniform stitching on both the top and bottom layers. This makes the machine suitable for a wide range of applications, including overcoats, uniforms, jeans, packaging, and decorative seams.
The JUK845 model features a small hook, while the JUK875 model comes with a larger hook. Both models allow for easy direction changes during sewing, providing flexibility for different types of projects. Whether you're working on thick fabrics or delicate materials, this machine delivers professional results with ease. Its durable construction and user-friendly design make it an excellent choice for both industrial and home use.
