Flat Section Spring BO is a heavy-duty compression spring with standardized ISO 10243 dimensions, designed for the most demanding industrial applications where maximum compression force, durability, and stable performance are required.
The orange marking indicates that these springs provide significantly higher compression force — 3–4 times greater than the BY series (yellow).
Key Characteristics
Type: Compression springs for die and mold applications
Series: BO — extra heavy load
Color: Orange — marking for maximum load springs
Standard: ISO 10243 — standardized body, rod, and length dimensions
Purpose and Applications
BO series springs are designed for use in the most demanding environments where maximum compression forces and high reliability are required, even under intensive load cycles:
heavy press equipment;
large dies and molds;
high-load mechanical systems;
automated production lines with intensive operation.
Advantages
✅ Maximum load capacity — provide one of the highest compression forces in this product line, allowing operation under heavy loads without deformation or excessive wear.
✅ ISO 10243 compliance — standardized dimensions ensure easy replacement, interchangeability, and universal selection of springs for different systems.
✅ Versatile application — suitable for heavy machinery, automated lines, and complex mechanical assemblies.
