Electroplating and polishing directly impact a part’s appearance, corrosion resistance, and durability. KT ensures uniform coating, strong adhesion, and smooth, consistent surface finishes through a stable finishing system. Even across different materials and complex geometries, we maintain consistent results while minimizing variation in color and surface roughness.
Detailed Description
This precision electroplated deep groove ball bearing is a core support and anti-friction component for various rotary transmission systems. Integrally formed by turning, quenching and superfinishing from GCr15 bearing steel, the inner ring, outer ring and rolling elements are treated with precision electroplating to form a uniform and dense chromium/nickel metal coating. It not only achieves a mirror-bright surface effect, but also significantly improves surface hardness, wear resistance and corrosion resistance, effectively preventing rust, wear and medium corrosion, extending service life under humid, acidic and high-dust conditions. The coating is firmly bonded to the substrate without affecting dimensional accuracy and fit tolerance, and can directly replace ordinary bearings in scenarios requiring higher anti-rust and wear resistance.
Manufacturing & Electroplating Process
- Bearing steel substrate processing: turning, quenching and tempering, centerless grinding outer/inner diameter, superfinishing raceway
- Pre-treatment: degreasing, rust removal and activation to ensure coating adhesion
- Precision electroplating: bright chrome/nickel plating process to control coating uniformity and density
- Post-treatment: cleaning, passivation and drying to remove residual plating solution and improve corrosion resistance
- Quality inspection: full inspection of dimensions, roundness, clearance, coating thickness, hardness and salt spray test
Overall process: Precision Electroplating + Bearing Superfinishing Process, focusing on surface strengthening and brightening through electroplating, meeting both performance and appearance requirements.
