Precision Linear Motion Shaft Assembly

Internal threading at the shaft end enables secure fastening to mating components, while the stepped cylindrical profile provides precise axial positioning within mechanical assemblies. This configuration is typical for drive shafts, linear motion guides, or hydraulic piston rods where concentricity between the mounting interface and the running surface is critical for smooth operation.

The part features distinct diameter transitions with sharp shoulders, requiring careful control of concentricity and perpendicularity to prevent vibration during high-speed rotation. The polished outer surface suggests a finish suitable for sliding contact with bushings or seals, demanding tight tolerance management on the outer diameter to ensure consistent fit and low friction.

Dalian Hanyee Industry utilizes high-precision CNC turning centers and external cylindrical grinders to achieve the required surface integrity and dimensional accuracy for such transmission components. Our facility, certified to ISO 9001, supports the production of custom shafts from stainless steel, alloy steel, or carbon steel, with optional heat treatment and surface finishing to meet specific wear-resistance requirements.
