Custom gears, from small to large
Since 1905 in Yokkaichi, Mie, Japan. Gear cutting up to 3,600 mm in outside diameter, gear grinding, and machining.
What we make
We cut external gears, internal gears, racks and worms. Customers usually bring their own material, and we cut the gears with our own gear cutting machines. We also make replacement gears to extend the life of older equipment whose parts are no longer produced.
Recent work includes gears for construction machinery, container ships, wind power generation and shield tunneling machines.
Our machining department makes parts such as brackets and shafts, from material procurement to drawings, and provides maintenance, overhaul and inspection.
