Shock-absorbing rubber coated pot magnets combine impactful resilience with strong magnetic force - ideal for industrial mounting, fixturing, and machinery applications. With a NdFeB core, protective rubber coating, and threaded mounting options, our magnets meet the needs of engineering teams and procurement buyers alike.
Design & Performance Highlights
- Material & Core: High-grade NdFeB + rubber composite, delivering reliable magnetic performance under industrial conditions.
- Thread Options: Available in M4, M6, M8, both internal and external threads, to match your mounting scheme.
- Tolerance: Standard dimensional tolerance ±0.05 mm, ensuring consistent fit and repeatability in your assemblies.
- Shock & Vibration Resistance: The rubber coating absorbs impact and reduces vibration, protecting both the magnet and contacting surfaces.
- Surface Protection & Electrical Insulation: Rubber layer prevents scratches and provides insulation in sensitive applications.
- Delivery Time: Typically 8–14 days for standard orders; customizable lead times for mass supply.
Magnetic Grades & Specifications
We offer multiple grades including N30, N33, N35, N38, N40, N42, N45, N48, N50, N52, with typical operating temperature limits of 80 °C (higher-temp options available on request). The magnet's residual flux density (Br), coercivity (Hc), and energy product (BHmax) follow industry standards for NdFeB materials.
Applications in Industry
These threaded rubber coated pot magnets are widely used in:
- Industrial equipment & machining - for holding, positioning, clamping parts
- Automation systems & robotics - magnetic fixtures, jigs, and tooling
- Automotive & vehicle assembly - for vibration-resistant mounting and magnetic supports
- Tool organization & workbench solutions - magnetic bases, tool holders
- Display & signage systems - mounting panels without damaging surfaces
- DIY & prototyping - flexible use cases where strong magnetism and surface safety are both needed
Custom Solutions & Supply Capability
We serve OEMs, system integrators, and magnet component distributors with full support for customization. You may specify: shape, size, thread type, rubber thickness, coating color, magnetic grade, and magnetization direction. We handle both small prototype runs and large scale bulk orders with consistent quality.
Sample Testing & Ordering Workflow
To ensure compatibility, we offer sample units for testing before placing larger orders. Submit your drawing or specifications (diameter, height, thread, rubber thickness, grade) and we will provide a quote and sample. Once approved, we move to production under strict quality control.
