A steel motor bell cover with vent holes punched after drawing. The bell profile stiffens the thin sheet axially, while the vents let the motor breathe and dump heat. This is a classic OEM replacement part – we can match your existing bolt circle and stack height from a sample.
Function and Design
A motor bell cover looks like the simplest item in a catalogue and is often the most demanding to make consistently. The motor bell cover is produced to print, with the features that carry function inspected first.
Key Features
- Vents are pierced with hard tooling after forming – clean edges, exact placement, no rework.
- Pricing steps down with volume, supported by in-house tooling.
- First article verified and production sampled, so batches stay consistent.
- Material: The motor bell cover runs on carbon steel (SPCC / DC01 or to print) as standard; hardness or temper per print on request.
- Process: multi-stage deep drawing of the motor bell cover with interstage annealing as depth requires, burr-free piercing on the second operation.
- Finish: Surface treatment for the motor bell cover is picked for its working environment, not from a catalogue.
- Size: The motor bell cover is built to your drawing – the family covers the common range, your dimensions are quoted per print.
- Custom: OEM/ODM to print: the motor bell cover quotation includes material advice and tooling cost.
Applications
Typical applications include lighting reflectors and covers, automotive sensor and motor housings, electrical enclosures and junction boxes.
