Advanced Tooling Architecture
The integrity of a bearing seat depends on the precision of its seat diameter and the flatness of its flange. Our stamping die addresses these requirements through:
Concentricity Control: We utilize high-precision ball guide posts and bushings to ensure the punch and die alignment remains consistent, preventing lopsided wall thickness.
Stress-Relieved Tooling: All mold bases undergo specialized stress-relief processing to ensure long-term dimensional stability, even under the vibration of 500-ton presses.
Automated Lubrication Channels: Integrated oil grooves within the die structure reduce heat buildup during continuous cycles, preserving the surface integrity of both the tool and the workpiece.

Optimized Production Performance
This bearing seat stamping die is not just a tool, but a production efficiency upgrade. Our design philosophy focuses on "Zero-Secondary Processing." By achieving precise piercing and flanging in a single stroke, we eliminate the need for post-stamping machining. We also provide customized scrap removal systems to prevent slug pulling, which is a common cause of downtime in bearing seat production lines.
