Precision Motor End Cap Metal Stamping

The Motor End Cap Metal Stamping is a precision-manufactured component featuring an integrated bearing pocket and flanged mounting surface. Produced using advanced progressive die stamping, these end caps deliver the dimensional accuracy required for electric motor assembly with ±0.1mm tolerance on critical bearing bore dimensions.

Suitable for a wide range of electric motors, generators, and industrial drive units, our end caps are available in diameters from 30mm to 250mm with custom bolt patterns and ventilation features per your design specifications.

Key Features

• Integrated Bearing Pocket: Precision-stamped bearing seat eliminates secondary machining
• Flanged Design: Secure mounting with pre-pierced bolt holes
• Wide Diameter Range: 30mm to 250mm covering fractional to medium horsepower motors
• Optional Ventilation: Custom louvered or perforated designs for motor cooling
• Multi-Material: SPCC cold rolled steel or 304 stainless for corrosive environments

FAQ

Q: Can you match the bearing bore to specific bearing sizes?
A: Yes, we can precision-stamp bearing pockets for standard bearing sizes including 6000, 6200, 6300 series and custom dimensions.

Q: Do you provide balancing after stamping?
A: End caps can be supplied as-stamped or dynamically balanced depending on motor speed requirements.

Q: What is the typical production lead time for custom end caps?
A: Tooling development takes 20-30 working days. First article samples are available within 5 working days after tooling completion.
