Product Description

PREMIUM RUBBER COATED POT MAGNETS - SCRATCH-FREE MAGNETIC HOLDING SOLUTION
 
Our Rubber Coated Pot Magnets combine the superior holding power of neodymium magnets with protective rubber coating, delivering scratch-free performance for delicate surface applications.
 
Featuring a multi-pole magnetic field design, these rubber-coated magnetic systems create a dense, shallow magnetic field on the holding face, ensuring exceptional grip and anti-slip stability.
 
Available in various mounting configurations, including external thread, internal thread, screwed bush, cylinder bore, and handle designs, our waterproof rubber-coated neodymium magnets are engineered for industrial-grade strength while protecting both the magnet and contact surfaces from damage.
 
Perfect for automotive signage, tool mounting, heavy-duty fixtures, and precision equipment positioning, these rubberized pot magnets offer unmatched versatility in colors, including black, white, and grey, to match your specific application needs.

FAQ

Q1: How fast can I get a reply?
A: You will receive our reply within 15 minutes during our work time, 08:00-18:00(UTC-8).
 
Q2: What information do I need to supply when I have an inquiry?
A: To get a precise quotation on time, pls inform us of the following details when you send an inquiry to us: Dimensions or drawing; Grade of Material, Magnetized direction; Surface coating(if necessary); Quantity and delivery terms.
If you don't have the above information, you can inform us of the application of the magnets, and our technician will provide it.
professional advice for you.
 
Q3: Can you offer customized sizes and shapes?
A: Yes, we could produce customized-sized, shaped magnets according to customers' requirements.
 
Q4: Can I have a free sample before mass production?
A: Yes. We could offer free samples if the magnets are in stock, but you need to pay the delivery cost. It may take a minimum of 7 days for production if your size is out of stock. For neodymium magnets, we have many different-sized samples in stock.
 
Q5: Can magnets be shipped by air or by express?
A: We could ship the magnets by air or by express with our magnetic shield package.
 
Q6: How about the quality of the magnets?
A: To ensure the quality of the products, every production procedure is inspected strictly by the professional QC team from all aspects. Besides, the Trade Assurance order will protect your payment, and make sure that we deliver on time and manufacture quality products as required.
 
Q7: Will the magnetism be weaker after years of use?
A: Yes, magnets do weaken over time. If you store permanent magnets correctly, neodymium magnets will likely lose less than 1% of their flux density over 100 years. The magnetism decline is neglected, that's why we call it a Permanent Magnet.
