Ito Gear Manufacturing is a specialist enterprise in the production and machining of gears and gear-related components. Its supply portfolio spans industrial machinery such as spinning machines, reduction gearboxes, pharmaceutical manufacturing equipment, and agricultural machinery, extending to specialised vehicles and household goods.
Ito Gear Manufacturing possesses the necessary equipment and expertise for gear manufacturing processes, establishing an integrated production system capable of handling everything from material procurement to completion in-house. The company can even reverse-engineer parts from physical samples without drawings, attracting orders from across Japan due to its technical capabilities.
Ito Gear Manufacturing's significant strength lies in its ability to reliably produce and deliver the required quantities at the precise time needed by customers through its multi-variety, small-lot production system. Flexibly accommodating orders from a minimum of one unit up to around 100 units, it adeptly handles production plans subject to frequent changes. Underpinning this capability is a production management system, supported by Ito Gear Manufacturing's proprietary system, enabling real-time progress monitoring of each product and internal operational status. It centrally manages everything from specification discussions and material procurement to manufacturing and final delivery, achieving efficient and highly accurate process and delivery schedule management.
Furthermore, the company's extensive machining equipment and advanced gear and gear grinding technologies, including tooth profile modification and tooth flank modification, are major attractions. We handle diverse machining requirements, including external and internal gears, bevel gears, worms, and gear grinding, catering to a wide range of needs from partial machining to delivery of finished products. We complete the entire process in-house, from lathe machining, gear cutting, milling, and slotting to inspection, packaging, and shipping. This enables us to respond to urgent requests and handle the refurbishment of difficult-to-machine parts.
Ito Gear Manufacturing has established an integrated system capable of handling all processes in-house under its proprietary process management system, from various machining operations through to inspection, packaging and dispatch. Furthermore, the company possesses advanced technical capabilities to restore damaged components without existing drawings, working directly from the physical part. This enables it to respond flexibly to urgent requests and challenging machining projects, offering a strong advantage in both responsiveness and reliability.
Ito Gear Manufacturing possesses equipment capable of in-house production of large bevel gears up to φ800, a capability rare nationwide. Previously, the company produced gears up to φ400 internally, outsourcing larger sizes. Following the closure of its outsourcing partner, Ito acquired the equipment, significantly enhancing its in-house machining capabilities. The presence of skilled technicians capable of operating the machinery proved advantageous, enabling stable production to commence immediately after the equipment's introduction. This is a field where few companies nationwide can offer such capabilities, leading to numerous enquiries from businesses previously struggling to find suitable suppliers.
