Product Overview
The rubber-coated pot magnet offered here combines a powerful neodymium (NdFeB) core with a protective steel pot and a rubber-coated outer surface - delivering firm magnetic hold while protecting attached surfaces and absorbing shock. This design suits heavy-duty fixtures, machine tools, assembly lines, and robotic end-effectors where holding strength, surface safety and durability are all critical factors. For industrial buyers needing reliable magnet bases for repeated installation or relocation, this pot magnet is a practical solution.
Core Construction & Specifications
- Magnet Material: Sintered Nd–Fe–B (rare-earth permanent magnet) - providing high magnetic energy density.
- Housing & Coating: The magnet is enclosed within a steel "pot" that channels flux to a single contact face, and covered with a rubber layer to protect surfaces and increase friction for shear resistance.
- Mounting Options: Threaded stud (internal or external) - common sizes M4 / M6 / M8; ensures easy mechanical mounting for jigs, fixtures or tool holders.
- Typical Sizes & Force Range: Common diameters from ~20 mm up to ~50 mm (custom sizes available). Holding force varies with size, typically from ~10 kg up to ~80 kg in ideal steel-to-steel contact.
- Operating Conditions: Standard versions rated for normal industrial environments; rubber-coated surface helps resist scratches and moderate wear. For demanding conditions, alternative coatings or housing options can be offered.
Because of its design - steel pot + directed magnetic circuit - the pot magnet can achieve magnetic holding several times stronger than a plain NdFeB disc of similar size.
Why This Pot Magnet Works in Industrial Settings
Reliable Holding with Surface Protection
The steel housing ensures magnetic flux is concentrated and directed to the work surface, maximizing clamping force. Meanwhile, the rubber coating prevents scratching or denting when attaching to painted or finished metal surfaces - making it suitable for fixtures, metal cabinets, automotive sheet-metal, or delicate assemblies.
Strong Grip and Vibration / Impact Resistance
Rubber adds friction and dampens shocks or vibrations - so even under lateral forces or impact, the magnet maintains hold better than bare magnets. This is especially valuable for heavy components, mobile rigs, or robotic tooling that experience dynamic loads.
Flexible Mounting & Easy Integration
With threaded studs (male or female) or threaded mounting holes, these pot magnets can be bolted or screwed onto frames, machine beds, brackets, fixtures, or jigs - enabling quick installation and removal without welding or permanent modification.
Durable and Long-lasting Construction
The steel pot protects the brittle magnet core from chipping or cracking. The rubber coating adds a protective layer and improves resistance against abrasion or surface damage - extending service life even under frequent use.
Suitable for Bulk Procurement & OEM Use
We support both small sample orders for testing and large bulk orders for industrial production. Customization - including size, thread type, coating, and magnetic strength - is available to match your project needs. That makes this pot magnet a reliable component for machine builders, automation integrators, fixture suppliers, and procurement teams.
Typical Application Scenarios
- Fixture bases and clamps for machining, welding, or assembly lines
- Robotic tool holders, end-effectors, or jigs needing firm hold and easy repositioning
- Mounting and holding metal panels, automotive sheets, or finished components without damaging surfaces
- Temporary or modular installations (signage, metal racks, equipment mounting) where mobility and non-invasive mounting are required
- Any industrial environment requiring strong magnetic hold, vibration resistance, and surface-safe contact
Packaging & Quality Assurance
Each pot magnet is individually wrapped with non-magnetic separators to avoid mutual attraction during transport. Bulk orders are shipped in magnet-safe crates, with padding, clear labeling, batch tracking and optional inspection reports. For OEM clients, we offer consistent quality control - magnetic force testing, coating integrity checks, dimensional inspection - to ensure reliable performance across batches.
FAQ
Q: Can I request a custom size or thread specification?
Yes - we support custom diameters, heights, threaded studs or holes. Provide your drawing or mount spec and we will produce accordingly.
Q: Does the rubber coating reduce magnetic holding force?
Slightly - rubber introduces a thin gap, which may reduce pull force compared to bare metal contact. However, the steel pot design helps focus magnetic flux and largely compensates for this difference.
Q: Are these pot magnets suitable for painted or coated surfaces?
Yes - rubber coating protects surfaces from scratching and improves grip on smooth or painted surfaces.
Q: Can I get samples before ordering in bulk?
Absolutely. We support small sample orders so you can test holding strength, fitment, and coating compatibility before committing to larger quantities.
