Core Features & Functions
1. High-precision Positioning The inner bore is precision-ground with a tight tolerance of 0 ~ -0.005 mm. When matched with the corresponding guide post, it ensures micron-level guiding accuracy, maintains coaxiality between the punch and die during stamping, and significantly reduces burrs and dimensional deviations in finished parts. The shoulder design enables quick and accurate positioning during press-fit installation, preventing the guide bushing from sinking or rotating, thus eliminating guiding failure.
2. Excellent Wear Resistance & Durability Made of SUJ2 bearing steel, which offers high carbon and chromium content. After heat treatment, it achieves uniform hardness and outstanding wear resistance—over 3 times higher than ordinary 45# steel. This makes it ideal for high-speed stamping and continuous production environments. The inner bore features oil grooves to store lubricant, reducing friction, preventing galling or seizure with the guide post, and extending the mold maintenance interval.
3. Wide Compatibility & Versatility As a standard MISUMI-style SGBH series component, it is fully interchangeable with most progressive dies, compound dies, and blanking dies in the market. The SGBH 25-50 size is a common choice for small-to-medium molds, compatible with φ25 guide posts, and suitable for various processes including blanking, bending, and drawing.
4. High Stability & Impact Resistance The material undergoes mature heat treatment to ensure uniform hardness throughout the part. It can withstand high-frequency impact forces during stamping without deformation or cracking, maintaining consistent mold accuracy over long production runs.
