Technical Specifications

Parameter	Key Details
Material	Stainless Steel 303 (free-machining grade, excellent for CNC turning; high corrosion resistance, non-magnetic; ideal for industrial equipment requiring low maintenance)
Processing	CNC precision turning, centerless grinding, keyway cutting, thread rolling, deburring, chamfering; dynamic balance testing (≤1g·cm unbalance for high-speed rotation); dimensional inspection with CMM for tight tolerance verification
Tolerance	Diameter tolerance ±0.002–±0.005mm (ultra-tight for precision fits); concentricity ≤0.003mm (minimizes rotational vibration); straightness ≤0.005mm/m (prevents bending under load); thread tolerance 4h (ISO standard for high-precision connections)
Surface Finish	Precision grinding (Ra 0.1–0.4μm, mirror-smooth for reduced friction); passivation (enhances corrosion resistance, meets RoHS/REACH standards); optional black oxide coating for aesthetic and anti-wear protection
Mechanical Properties	Tensile strength ≥515 MPa; yield strength ≥205 MPa; hardness ≤200 HB; operating temperature -270°C to 870°C; resistant to mild acids, alkalis, and industrial fluids
Compatibility	Fits servo motors, linear motion systems, packaging machinery, and printing equipment; designed for heavy radial/axial loads; compatible with ball bearings, roller bearings, and precision gear assemblies

Application Scenarios
