About Magnets

Ceramic Magnets

Ceramic magnets resist demagnetization better than other magnets and are an economical choice. They resist temperatures up to 400° F.

Ceramic Magnets with Unthreaded Hole

Ceramic magnets resist demagnetization better than other magnets and are an economical choice. They resist temperatures up to 400° F.

Encased Ceramic Magnets with Unthreaded Hole

Ceramic magnets resist demagnetization better than other magnets and are an economical choice. They resist temperatures up to 480° F.

Encased Ceramic Magnets with Threaded Stud

Ceramic magnets resist demagnetization better than other magnets and are an economical choice. They resist temperatures up to 140° F.

Encased Ceramic Magnets with Threaded Hole

These ceramic magnets resist demagnetization better than other magnets, and have a metal case to protect the magnetic material. They resist temperatures up to 175° or 245° F.

Encased Magnets with Mounting Plate

To add a magnetic surface anywhere, install the mounting plate, then screw on the magnet.

Encased Ceramic Magnets

A case protects the magnetic material.

Nonmarring Encased Ceramic Magnets

A plastic case protects the mounting surface as well as the magnet.

Flexible Magnets

These magnets are made of corrosion-resistant ceramic and bonded with rubber for flexibility.

Flexible Disc Magnets

These discs are made of corrosion-resistant ceramic and bonded with rubber for flexibility.

High-Temperature Flexible Magnets

Unlike other flexible magnets, these resist demagnetizing at temps up to 250° F.

Ferrite Cores

Often used as inductors and transformers in electrical circuits, these cores generate a magnetic hold when magnet wire is wrapped over them and energized.

Magnetic Machine Vises

Magnetic Workholding Plates

The entire surface of these plates is magnetic to provide a powerful hold for grinding, drilling, and electrical discharge machining (EDM). Pull the handle to switch the magnets on and off.

Magnetic Workholding Chucks

To grind, drill, lightly mill, and machine parts that rotate around an axis, these chucks hold parts in place magnetically so you can access their inner and outer diameters.

Magnetic Filters

Magnetic Rod Filters

These filters are designed without guide rods to prevent wet and sticky material from blocking flow.

Rods for Magnetic Filters

Replace individual rods in an existing filter or create a custom filter.

Magnetic Rod Filters with Guide Rods

The guide rods direct flow to the magnetic rods. They’re helpful in removing dry particles from fine powder and low-flow applications.

Magnetic Plate Filters

These filters are designed without guide rods to prevent wet and sticky material from blocking flow.
