BALLEX
Engineered for demanding operations.
BALLEX products can be manufactured in different chemical compositions and sizes from 16 mm to 125 mm according to customer requirements.
Raw materials are accepted only after rigorous incoming-control procedures. Steel bars heated in induction and/or natural-gas furnaces are prepared for rolling with homogeneous, fully controlled heat distribution. The automated heat-control system manages every stage of heat treatment precisely. In the continuous heat-treatment process, every ball is processed with the same thermal parameters, producing a uniform and standard hardness distribution.
TECHNICAL RANGE
| Product | Alloy grade | Hardness |

| BALLEX BALLS (Ø mm): 16-20-25-30-35-40-50-60-70-80-90-100-110-125-140 | SAE 1060-1065-1070-1080-1090 | 56–65 HRC |
Ballex Features
Volumetric Hardness Analysis
A section is cut through the centre of each test ball by wire EDM and used for volumetric hardness analysis.
Special Sizes
Ballex steel balls are manufactured across a broad 16–140 mm diameter range with tight dimensional tolerances.
Hardness Control
Before shipment, surface, core and volumetric hardness values are checked using Rockwell hardness-testing equipment.
