Steel Metal Reduction Custom Precision Machine Wheel Transmission Starter Shaft Spline Pinion Planetary Sun Drive Spur Gear

This gear is widely used in various applications such as motors, electric cars, machinery, toys, agricultural machinery, and cars. Its hardened tooth surface ensures durability and longevity. The gear is designed to be an external gear and is manufactured using the cut gear method. Its toothed portion shape is curved. Made from stainless steel, this gear is known for its strength and resistance to corrosion.

Product Description

The Customized machined machining gears are made using CNC machining, CNC milling, and CNC lathe machining processes. They can be manufactured from various materials such as steel, stainless steel, carbon steel, brass, copper, aluminum, nylon, PA66, ABS, PP, PC, PE, POM, PVC, PU, TPR, TPE, TPU, PA, PET, HDPE, PMMA, and more. The gears adhere to ISO9001 and ISO14001 quality control standards.

The gear dimension bore tolerances are within -/+0.01mm, and the quality standard follows AGMA, JIS, and DIN guidelines. Surface treatments like blackening, plating, anodizing, and hard anodizing are available. The gear hardness ranges from 30 to 60 H.R.C. The size and color of the gears can be customized according to customer drawings, and various surface finishes such as polished or matte surface, painting, texture, and vacuum aluminizing can be applied. The gear dimensions have a tolerance of ±0.01mm or higher precision.

Samples can be provided at a price of US$ 10 per piece with a minimum order quantity of 1 piece. Customization options are also available for customers.

The gears are carefully inspected at every step of the production process to ensure high quality. The workers are trained to spot any defects in production, and quality control personnel check the gears to meet all dimension tolerances. Inspection records are kept for three years. Customers are regularly updated with pictures of the production process to ensure transparency and allow for error detection. The company is committed to providing excellent quality and customer satisfaction.

Quality Control Process

The quality control process includes inspecting the raw materials (IQC), checking the details before production, conducting full inspection and routing inspection during mass production (IPQC), checking the gears after production finished (FQC), and checking the gears before they are shipped (OQC).


The company offers mold designs as per customers’ gear drawings. Molds drawings are submitted to customers for review and confirmation before production. Samples with dimensions and cosmetic inspection reports, as well as material certifications, are provided. Inspection reports of important dimensions and cosmetic are given for batch parts.

Packing and Shipment

Gears are packed securely in PP bags in CTNS, suitable for express shipping, air shipment, or sea shipment. Shipping is arranged via UPS, DHL, FedEx, TNT, or sea shipping based on customer requirements. The trade terms include EXW, FOB Shenzhen, or CIF. The company ensures careful and prompt delivery of all shipments.
