48mm Shaft Pulley

The 48mm Shaft Pulley stands out for its high durability and high load-bearing capacity, typically installed directly with a 3-phase 22kW 30Hp electric motor. It is widely applied in various industrial fields, helping the transmission process run efficiently and achieve optimal performance.

What is the design of the 48mm Shaft Pulley?

In terms of design, the pulley is made from durable materials such as cast iron, steel, or iron, giving the product good load-bearing capacity and effective wear resistance, ensuring stable operation over a long period. With a simple design, this pulley is easy to install into motors and machinery systems, ensuring smooth, quiet, and efficient power transmission.

Structure of the 48mm Shaft Pulley

The pulley is designed with a bore diameter of 48mm. The detailed structure of this device consists of 3 main parts: the pulley wheel (containing grooves), the hub (pulley center), and the keyway or set screw.

• Bore hole (48mm diameter): The space at the center of the pulley to fit with the motor or machine shaft.
• Keyway: Located inside the bore hole, carved with a small slot to install the key, helping the pulley lock tightly and transmit torque directly from the 48mm shaft without slipping.
• Hub: The thickened section at the center of the pulley surrounding the bore hole, usually accompanied by a threaded hole on the side to secure a hexagon socket screw (set screw) to fix the pulley on the shaft.
• Pulley body and working surface: A circular wheel cast from cast iron, steel, aluminum, or plastic. The outer surface is specially designed (trapezoidal grooves for V-belts, teeth for synchronous timing belts, or flat grooves for flat belts) to receive and transmit force.
• Spokes or solid disc: The section connecting the hub and the wheel rim. Depending on the outer diameter size, this part can be a solid disc (one-piece) or spokes (fan blades) to reduce weight.
