Manufacturing of guide pillars, guide pin bushings, slide rails, bearings, shaft centers, cutters, mechanical columns and elements and components of various precision automatic machines, etc. Among these, the manufacture of bearing and shaft centers is the main application of this material.
1. Material: the bearing steel of JIS G4805 SUJ-2 is good in hardness and abrasion resistance. It is very stable with less deformation after heat treatment. Low in oxygen content and high in modularization, the processing of this material is easy and time saving. 2. Optional product: SUJ-2 ground bearing steel bar, SUJ-2 high frequency ground bearing steel bar and SUJ-2 chromium plated bearing steel bar. 3. Surface hardness: HV 800(minimum) up. 4. Hard chrome thickness: 20 micron. 5. Case depth: 1.5mm ~ 2.5mm. 6. Induction hardness: HRC 62 ± 2. 7. Surface roughness: Ry 0.6~1.4s Ra, 0.2μm~0.4μm. 8. External diameter accuracy: h7, h8, f8, g6.
