Higher speed, longer life, the operation is more convenient, more comfortable, Widely used in thin, medium, heavy fabric, available with both narrow edge seaming and wide edge seaming.


Adopts main shaft direct drive technology without belt drive.

Low noise

Small vibration, low noise, less wear and avoid contamination of fabric

Super high speed

The speed can be adjusted from 0 to 8500rpm,low increase of temperature, and stable running.

Equipped with adjustable suction device

Equipped with adjustable suction device (controlled by electromagnetic valve)
1. suction only for start and stop
2. Continuous suction

Totally enclosed type direct-drive needle bar

The acting foce on the needle bar points directly to the center of needle bar; the totally enclosed type needle bar puts an end to the dust incasion and oil leakage and reduce the abrasive damage of the needle bar and needle bar collar,and reduce the abrasive damage of the needle bar and needle bar collar.

Up-to-date feed dog rack sealing device and straight-needle forced oil return

This is an entirely sealed machine with direct oiling solution to oiling system, can get the oil recovery. Automatically oiling system with filter pump. To prevent the materials being polluted by the oil sludge,is added to clean the oil sludge from lubrication. (The yellow is the sealing ring). (Old model only have two pices, but 900 series have four pices)

Patented presser foot

Machine of the series are equipped with the up to date patented presser foot whose independent fabric hole down piece can be adjusted rightward/leftward as per the changes in cup seaming width such that the edge surling can be effectively avoided during high speed sewing operation.

Oil filter

The device can guarantee the cleanliness of lubricating oil, and optimize the running environment of machine; In addition, the forced oil return device can avoid oil leakage and quality of sewn articles can be further improved(Old-style overlock sewing machine is not equipped with a oil filter, and it is impossible to guarantee the long-term cleanliness of lubricating oil)

HR silicone oil cooling device

The HR silicone oil device can effectively reduce the needle temperature and avoid broken thread and fabric molten in case of high temperature such that the synthetic threads and fabrics with poor heat resistance can be applied in the high speed sewing operation and that the stitches can be stable and pleasing to the sye.
