Marine Transmission Pinion Gear

The Marine Transmission Pinion Gear is manufactured for marine transmission-related applications and can be customized according to equipment drawings, existing prototypes, and specific project requirements.
Available steel materials include 20CrNiMo, 17CrNiMo6, 40Cr, 20CrMnti, #45 Steel, 42CrMo, and 18CrNIMo7-6. Other steel grades that can be normally sourced in China may also be considered according to the actual project. Copper and aluminum components are currently not supported.
The marine gear series mainly focuses on relatively smaller products, with diameters controlled within 1–2 meters. Surface appearance depends on the processing stage. After shot blasting, products normally appear black-gray. After grinding, the surface becomes bright white.

Hangzhou Kaishen Machinery Co., Ltd. has long focused on high-precision gears, clutch assemblies, and transmission components and has established a marine gearbox gear product range.

The company is located in Xiaoshan, Hangzhou and has more than 30 employees. Its core team covers engineering, production management, and quality inspection.

Complete gear machining and heat treatment production lines allow mechanical processing, heat treatment, and quality inspection to be organized within the same manufacturing system. This provides a practical production foundation for drawing-based customization, sample development, and regular batch supply.

International purchasing projects can begin with sample development according to actual project schedules. OEM and ODM services are supported, and production can be based on technical drawings or prototypes.

Customized samples normally require 45–90 days. The minimum order quantity is 2,000 pieces for the same specification. Mature batch products generally have a production cycle of approximately 30 days, while customized projects normally require 45–90 days.

For identical repeat orders, preparation time for new molds and customized tooling can be reduced. Hangzhou Kaishen Machinery Co., Ltd. began expanding overseas business in 2022 and has export experience in Southeast Asia and Europe.

Professional inspection equipment is used for routine quality checks. Inspection normally includes sampling during production, finished-product sampling, and individual appearance checks before packaging. Third-party inspection can also be arranged according to the buyer's purchasing process.

Photos or videos may be provided during production to help customers follow important order stages. Finished products can be packed in wooden cases or on pallets, while export orders use wooden cases. A one-month warranty is provided.

These arrangements support continued purchasing of the Marine Transmission Pinion Gear from sample confirmation through regular production and later repeat orders.
