Handan Jinmai Fastener Manufacturing Co., Ltd. relies on precision forging technology to provide a full range of carbon steel/stainless steel Ball Eye product series, supporting customized hole diameters, load-bearing strengths and corrosion resistance levels to meet the needs of different working conditions.
1. High-Strength Load-Bearing
Dynamic load capacity exceeds 210 kN, meeting the mechanical requirements of UHV transmission lines for wind vibration and ice load resistance.
The ball-and-cup joint structure eliminates stress concentration and reduces the risk of cable breakage.
2. Long-Term Corrosion Protection
Utilizing hot-dip galvanizing (Grade C5) or Dacromet coating, and withstanding over 1,000 hours of salt spray testing, it withstands harsh environments such as coastal areas and industrial pollution zones.
3. Intelligent Adaptability
Supports modular assembly with pre-twisted wire fittings, suspension clamps, and other components, increasing optical cable system installation efficiency by 30%.
Forging Materials: Q235B carbon steel/304 stainless steel precision die forging, grain size ≥ Grade 5 (GB/T 6394)
Heat Treatment: Quenching and tempering (quenching + tempering), hardness HRC 28-32, impact toughness ≥ 40J (GB/T 229)
Surface Corrosion Protection: Gradient galvanizing (average zinc layer ≥ 86μm) ISO 1461
Dimensional Inspection: Full-scale scanning with a three-dimensional coordinate measuring machine, tolerance ±0.1mm (GB/T 1804)
The Handan Jinmai factory is equipped with CNC lathes, friction presses and automated shot blasting production lines to ensure the consistency of batch products.
QP-7/16 (70kN), QP-20 (210kN), QP-30 (300kN)
Customized bore diameter range: Ø16mm to Ø50mm
