LARGE SCALE INDUSTRIAL GEARS

GEAR

Specialized Welding Technology / Hokuriku Plant

We produce Large Scale Industrial Gears by welding dissimilar content of steel!!

Utilizing know-how cultivated in the field of special welding, can welding is adopted for large gears used in sheet metal presses for automobile body lines and large reduction gears.
By using High strength steel on the tooth surfaces, compared to gears made of cast steel we are able to produce large scale gears that with higher accuracy, higher durability, and lower weight.
