High Post Sewing Machine (8B) Gear Noise Reduction Spiral Gear
What are the characteristics of high post sewing machine gears?
The size of the gear can vary according to the specific machine and
its intended use, with different number of teeth to achieve a
specific stitch pattern or feed mechanism. The gears of industrial
sewing machines can reduce noise, heat dissipation, wear
resistance, and many industrial sewing machines use spiral gears to
achieve higher torque transmission, which can effectively handle
heavy loads
