Bearing seat production often faces challenges like material thinning or uneven wall distribution. Our engineering team utilizes Forming Simulation (CAE) before cutting steel. By analyzing the metal flow in the deep-drawing stage, we optimize the draw bead design and pressure pad force. This proactive approach eliminates the trial-and-error phase, ensuring the first sample is as close to the final drawing as possible.
Quality isn't just a final check; it's built into the die.
Incoming Material Verification: Every block of die steel undergoes ultrasonic flaw detection.
In-Process Monitoring: CNC machining centers are calibrated weekly to maintain absolute positioning accuracy.
CMM Validation: Each bearing seat sample is verified via 3D Coordinate Measuring Machines to confirm concentricity and cylindricity.
Our bearing seat stamping solutions are widely integrated into:
Automotive Systems: Alternators, water pumps, and tensioner pulleys.
Electric Motors: Housing for domestic appliances and industrial power tools.
Agricultural Equipment: Heavy-duty pillow block housings and conveyor rollers.
FAQ
Q1: How do you guarantee the concentricity of the bearing seat? We use a one-step finish-forming process in the final station of the progressive die, or specialized locating pins in stage dies, to ensure the seat and the outer flange share the same axis.
Q2: What is your typical lead time for a new die set? For a standard bearing seat die, the design phase takes 7 days, followed by 35-45 days for machining, assembly, and T1 testing.
