Marine Gearbox Drive Gear

The Marine Gearbox Drive Gear is manufactured for marine transmission system applications and can be customized according to customer technical drawings or existing prototypes.

Available material options include 18CrNIMo7-6, 20CrMnti, 40Cr, 17CrNiMo6, 42CrMo, 20CrNiMo, and #45 Steel. Other steel grades that can be normally sourced in China may also be considered according to actual project requirements. Aluminum and copper parts are currently not supported.

The marine gear series mainly handles relatively smaller products, with required diameters within 1–2 meters. After shot blasting, the surface normally appears black-gray. After grinding, the finished surface becomes bright white.

Hangzhou Kaishen Machinery Co., Ltd. manufactures several transmission component categories, including marine gearbox gears, construction machinery transmission gears, and axle gears.

According to the provided company information, the factory has supplied equipment manufacturers including Hangzhou Advance Gearbox Group and XCMG. The company also has product export experience in Southeast Asia and Europe.

Continued investment in mechanical machining equipment has allowed the company to establish gear machining and heat treatment production lines. These resources support new product development, batch manufacturing, and repeated supply for marine gearbox projects.

New products can begin with sample development. OEM and ODM services are supported, and production can be organized directly from drawings or prototypes.

Customized sample development usually requires 45–90 days. The minimum order quantity is 2,000 pieces for the same specification. Mature products generally require around 30 days for one batch production cycle, while customized projects normally require 45–90 days.

During production, customers may request photos or videos. Dedicated personnel record and track delivery schedules. For identical repeat orders, preparation time for new molds and customized tooling can be reduced, making planned replenishment easier to coordinate.

The factory uses professional inspection equipment and can cooperate with third-party inspection. Routine quality control includes production-stage sampling, finished-product sampling, and individual appearance checks before packaging.

Finished products may be packed on pallets or in wooden cases. Export orders use wooden cases. A one-month warranty is provided.

For larger purchase quantities, pricing conditions can be discussed according to the actual order volume. This gives purchasing teams a defined process from customization and inspection to continued supply of the Marine Gearbox Drive Gear.
