Gears

We draw on expertise gained over the course of 80 years working to strict, in-house standards to manufacture unique, high-precision gears. In order to meet customer needs with sophisticated solutions, we pursue precision and quality by means of an integrated production system and innovative product design proposals, flow analysis, structural analysis, material selection, mold design, molding, and measurement capabilities.

High precision

Double helical gear

High-precision molds and optimal molding conditions are key to the achievement of high levels of precision.

Mass-production criteria for high-precision gears that meet or exceed JIS Class 5 and JGMA Class 2 standards and integration of mold machining accuracy and molding technology enable us to produce high-precision gears.
