The world’s highest max. sewing speed 2,500 rpm enhances productivity

The maximum sewing speed of 2,500 rpm has been achieved 
by the adoption of an optimal machine structure for high-
speed drive. The speed is significantly enhanced from the 
former 2,200 rpm level.
By enhancing the rigidity of the needle bar-area parts (patent 
pending) and having the feed mechanism and needle bar 
rotating mechanism servo-controlled, the operating time has 
been reduced, resulting in 13% reduction of the machine time 
compared with the conventional model.

Enhanced productivity with the world’s 

highest max. sewing speed 2,500 rpm

Fine stitches with high-precision 

stitch point

Large arm pocket allowing 

smooth material handling

Easy-to-use operation panel

The further-improved, reliable sewing mechanism is optimally controlled by the 
most advanced electronic technology.
Productivity and sewing quality are combined at the highest level ever.
