Weld-on sprockets are widely used in various industrial applications, especially in heavy-duty machinery. These sprockets are known for their durability, reliability, and high performance. Our 40X25 Weld-on Sprocket with Hub is a perfect example of our dedication to providing high-quality sprockets to our clients.
A weld-on sprocket is a type of sprocket that is designed to be welded directly onto a shaft. It is commonly used in applications where the shaft is not removable or where a keyway cannot be cut into the shaft.

Our weld-on sprockets are made from high-carbon steel, alloy steel, or stainless steel, depending on the application requirements. We follow a rigorous manufacturing process that includes material selection, cutting, stamping, forging, machining, heat treatment, surface hardening, surface treatment, and quality inspection.
Selection of Material: We choose the material based on the application requirements, such as load, speed, temperature, and environment.
Cutting: We use precision cutting machines to cut the raw material into the desired size and shape for the sprocket.
Stamping and Forging: We use stamping machines or forging machines to form the sprocket teeth, hub, and other features.
Machining: We use CNC machines to refine the sprocket teeth and hub to achieve high dimensional accuracy and surface finish.
Heat Treatment: We use heat treatment to enhance the mechanical properties of the sprocket, such as hardness, toughness, and wear resistance.
Surface Hardening: We use surface hardening to improve the wear resistance of the sprocket teeth and prolong the service life.
Surface Treatment: We use surface treatment, such as plating or painting, to prevent corrosion and enhance aesthetics.
Quality Inspection: We perform multiple quality inspections to ensure the sprocket meets the specifications and standards.
Weld-on sprockets are widely used in various applications, such as conveyor systems, agricultural machinery, construction equipment, mining machinery, and industrial power transmission. They are especially useful in applications that require a high torque and heavy load.
For applications that require special design or size, we allow the user to choose a suitable hub for welding based on the actual shaft diameter.

We offer various hub options for our weld-on sprockets, including round bore, hex bore, square bore, and spline bore, to fit different shaft configurations.
Maintenance of the sprocket is essential for ensuring its optimal performance and prolonging its service life. We recommend performing the following maintenance tasks regularly:
Common problems that can occur with the sprocket include tooth skipping, breakage, wear, noise, and chain derailing. These problems can be caused by various factors, such as improper installation, misalignment, overloading, or lack of lubrication. We recommend addressing these problems promptly by:
In addition to our weld-on sprockets, we also offer other types of sprockets, such as platewheel sprocket, QD sprocket, taper lock sprocket, and others. We also provide matching chains for each type of sprocket to ensure optimal performance and compatibility.
