Rubber Jacket · 5 Fixing Options
The jacket does three jobs at once, and none of them is magnetic.
A rubber coated magnet wraps a neodymium pot in a moulded elastomer jacket that grips, absorbs impact and keeps the steel cup off painted metal.
Five fixing styles share that jacket, so the same body can be threaded, bolted or hung.

A bare steel cup scratches paint, slides under side load and chips at the edge. The jacket answers all three.
Rubber has a higher friction coefficient than steel, so the magnet resists sliding better than its pull figure suggests.
Rubber coated neodymium magnets also absorb the impact of a magnet snapping onto a surface. A moulded jacket takes the hit instead of the magnet edge.
Choose by how the magnet attaches to the thing it holds, not by the size of the cup.
A tapped bore takes a bolt from the fixture side.
M4 – M8
A projecting stud threads into a tapped bracket.
M4 – M8
A brass bush adds thread depth without a thicker body.
M4 – M6
A moulded grip lets an operator place and peel by hand.
20 – 45 kg
A saddle on the face cradles cable, hose or conduit.
Ø8 – 16 mmWhere the load needs a hook rather than a thread, a magnetic hook with a rubber body does the same job without marking the wall.
Rubber coated magnet with female thread has a metric internal screw thread, which can be fastened with objects through threaded bolt to minimize the scratches to the contacted delicate surface. It is also called rubber coated pot magnet with female thread, or NdFeB rubber coated magnet with internal thread.
Rubber coated magnets with screwed bush are based on high-performance magnets such as Neodymium Iron Boron magnets, which are covered with a layer of rubber material on their surface through special processes, and the screwed bush is machined on one end of the pot magnet. This design not only retains the strong holding force of the magnet, but also increases the durability and installation convenience of the rubber coated pot magnet.
Rubber coated magnets with handle have Santoprene rubber that can protect fine surface areas. It has M4 or M6 internal threads and a 64mm long screw in the handle. For various standard models, the rare earth magnets weigh 20 to 220 grams and have a holding force of 3 to 42 kilograms.
Rubber coated magnet for cable holding is specially designed for organizing and mounting cables, wires, ropes, hoses or pipes against the metal or steel surface conveniently. The Neodymium pot magnet system with a rubber coating protects the metal adhesive surfaces from scratching and the displacement force is increased. As a leading magnet supplier, we manufacture rubber coated magnets is various designs, forces, shape, sizes, etc.
Rubber coated magnet with male thread is ideal for holding objects when you consider much about the contacted delicate surfaces without scratch damage caused. Rubber coated pot magnets with male threads are a special type of magnet product that perfectly combines the flexibility of rubber with the adsorption force of powerful Neodymium magnets.
Rubber costs a little pull. It buys back more in surface protection and slide resistance.
Steel cup, plated, no jacket
Elastomer jacket over the same cup
The jacket is a working part, so its grade is quoted with the magnet.
| Cup Ø | Pull force | Jacket material | Hardness | Working temp |
|---|---|---|---|---|
| 22 mm | 4 kg | TPE | 65 Shore A | 80 °C |
| 31 mm | 7 kg | TPE | 65 Shore A | 80 °C |
| 43 mm | 14 kg | TPE / NBR | 70 Shore A | 80 °C |
| 54 mm | 22 kg | TPE / NBR | 70 Shore A | 80 °C |
| 66 mm | 45 kg | TPE / NBR | 70 Shore A | 80 °C |
NBR is specified where oil or coolant is present. TPE is the general-purpose choice and stays flexible at low temperature.
Wipe the rubber and the target surface. Dust on rubber behaves like an air gap and cuts holding force quickly.
Let the magnet find its own contact first. Tightening a bolt before it seats pulls the jacket out of shape.
Lift one edge and roll the magnet off. Pulling straight up stretches the jacket and can tear the bond.
Share the mounting method and surface type. We match a standard body or quote a mould.
