Parameter	Key Details
Material	Alloy Steel (4140/4340): High tensile strength (≥750 MPa), excellent hardenability, fatigue resistance; base material for heavy-duty small rollers.Hard Chrome Plating: Thickness 0.005–0.01mm
Processing Capabilities	Precision CNC turning (single-spindle for micro-rollers), drilling (axial holes for shaft mounting, diameter ≥2mm), tapping (M2–M6 threads), chamfering (edge radius 0.1–0.5mm to prevent material snagging), deburring; heat treatment (quenching/tempering to 28–32 HRC before plating); hard chrome plating (polished finish post-plating)
Tolerance & Precision	Outer diameter tolerance ±0.005–±0.01mm; inner bore tolerance H6 (for male/female shaft fit); concentricity ≤0.003mm (eliminates vibration during high-speed rotation); length tolerance ±0.01mm; surface roughness Ra 0.05–0.2μm (mirror-like finish for smooth material contact)
Surface Finish & Treatment	Hard chrome plated (mirror polished for printing/packaging applications);
Compatibility	Fits printing machinery (label printers, offset presses), textile equipment (fabric guide rollers), packaging machines (film stretching rollers), micro-motors, and precision instrumentation; compatible with stainless steel shafts, miniature ball bearings, and plastic guide rails

Application Scenarios

Printing & Labeling Machinery: Small hard chrome plated male rollers for label die-cutting—mirror finish ensures uniform ink transfer, wear resistance withstands high-frequency paper/film contact.
Textile Manufacturing: Female rollers for yarn guiding systems—precision inner bore ensures smooth shaft rotation, chrome plating resists fiber fraying and oil contamination.
Packaging Equipment: Micro grooved rollers for plastic film stretching—tight tolerance maintains consistent film tension, corrosion resistance adapts to factory humidity.
Precision Instrumentation: Small male rollers for optical equipment adjustment mechanisms—high concentricity eliminates rotational vibration, ensuring accurate positioning.
Electronics Assembly: Female rollers for PCB conveyor lines—micro-dimension accuracy matches tiny PCB dimensions, hard chrome finish resists solder flux corrosion.
