Flat grippers are magnetic systems with which decorative articles, suspensions in shop windows or similar are suspended. In fixture and machine construction, flat grippers are glued or screwed in. Flat grippers are round magnet systems with various mounting options such as threaded pins or bushes.
Product features to your advantage:

• Magnetic materials of the flat grippers can be: Ferrite, neodymium, samarium-cobalt or AlNiCo. We would be pleased to inform or advise you in order to find the suitable flat gripper for your application.
• Offers a temporary, unobtrusive and discreet holding option that leaves no traces.
• The systems are completely shielded thanks to the steel cup (stainless steel versions also available).

Rubber coated neodymium pot magnets are strong and durable magnetic assemblies with a threaded center hole (internal female thread) and protective rubber coating. Made with N35 neodymium disc magnets attached to a flat steel disc and coated with black isoprene rubber which leaves no marks and prevents surfaces from scratching. The protective rubber coating protects magnets from corrosion or oxidation for sustained use in outdoor environments. It also prevents magnets from chipping easily and provides more slip-resistance than other types of coated or uncoated magnets.

Rubber coated magnets are high in magnetic strength and weatherproof so they are ideal for indoor and outdoor applications where high magnetic strength s required. They are frequently used for holding, mounting and fixing purposes, from mounting lights or fixtures to equipment repair, holding tools and organizing items in warehouses, workstations and outdoor areas.

• Strong pull force, waterproof, durable, high traction, corrosion resistant, temperature resistant, magnets do not easily chip.
• Constructed with N35 Neodymium magnet encased in a steel structure & coated with a protective rubber coating.
• Internal Female Thread accommodates standard fasteners & attachments.
• NdFeB Magnets are axially magnetized (through the thickness).
• Isoprene Black Rubber Coating is approx. 0.03” thick.

Neodymium Magnets Features & Characteristics
Grades & Materials - Neodymium magnet materials in both standard and premium grades for reduced production and lead times. We offer sintered neodymium magnets in grades ranging from N30 to N55.
Sizes & Shapes - Sizes for standard Neodymium Iron Boron rare-earth magnets range from a few millimeters to approximately 150 mm, while assemblies can weigh up to several tons. Standard shapes include discs, blocks, rings, and arc segments in various sizes and grades. Non-standard shapes and sizes can be custom fabricated exact specifications from raw stock.
Temperature Considerations - Neodymium magnets are temperature sensitive. For applications in which the magnet may be exposed to temperatures in excess of about 250°F (120°C), careful consideration must be given to the choice of magnet grade and the magnetic circuit.
Manufacturing Methods - Due to the relatively brittle nature and high-magnetic strength of NdFeB magnets, cutting and grinding should be done prior to magnetization. We are fully equipped to machine these materials to virtually any shape and size for your project’s specialty requirements using our in-house grinding and EDM facilities. Finishing to tolerances of +/-0.05mm can be achieved, as required.
Surface Treatments - Neo magnets are susceptible to oxidation, so painting, epoxy coating, or plating is highly recommended to prevent corrosion. The common surface treatments include nickel plating, zinc, or epoxy coatings.
Handling & Storage - Neodymium materials are relatively brittle, but are magnetically very strong. They must therefore be handled carefully to avoid injury to personnel and damage to the magnets.

Neodymium magnets have replaced alnico and ferrite magnets in many of the myriad applications in modern technology where strong permanent magnets are required, because their greater strength allows the use of smaller, lighter magnets for a given application. Some examples are:

• Head actuators for computer hard disks
• Mechanical e-cigarette firing switches
• Locks for doors
• Loudspeakers and headphones
• Mobile phone speakers, taptic feedback and auto focus actuators
• Magnetic bearings and couplings
• Benchtop NMR spectrometers
• Electric motors
• Electric generators for wind turbines (only those with permanent magnet excitation)
• Voice coil
• Retail media case decouplers
• In process industries, powerful neodymium magnets are used to catch foreign bodies and protect product and processes
• Identifying precious metals in various objects (cutlery, coins, jewelry etc.)
