1. Material: 45# steel

2. Manufacturing Process: Cutting to size, rough turning, heat treatment, finish machining, secondary operations, deburring

3. Dimensional Features: The shaft adopts a stepped, rotating design, with bearing‑fit journal sections, gear‑mounting locations, threaded segments, and oil‑seal grooves distributed along its length. Using the center holes at both ends as a common datum, the entire shaft achieves high concentricity. Available in sizes ranging from miniature fine shafts to heavy‑duty roller shafts several meters long, it is suitable for a wide variety of equipment load requirements.

4. Surface Treatment: The mating surfaces are ground to a bright finish with low roughness to minimize frictional losses; non‑mating surfaces are blackened or galvanized for corrosion protection; highly wear‑resistant journal surfaces may be chrome‑plated to enhance corrosion resistance and wear performance; the finished product is coated with anti‑rust oil for storage.

5. Product Applications: Automation equipment, gear reducers, machine tools, and core transmission components for construction machinery—used to transmit torque, support bearings and gears, and deliver rotary power output.
