Ferrite ring magnets, also known as Ceramic Ring Magnets, come in a wide range of sizes. They are often used in loudspeakers and in resonance imaging and torque drives. Other applications for this permanent magnet include holding, door closures, joinery, and light fixtures. Ceramic Rings are similar to Ceramic Discs but with a hole in the middle, which makes them a versatile magnet option. One popular application is the fishing game, tied on a piece of string, or to pick up pins and needles. Ferrite magnets have less magnetic strength (due to the hole) but their inexpensive pricing makes them a customer favorite.

Magnetic Ring Material: SrO OR BaO and Fe2o3
Magnetic Ring Grade: Y10T,Y20,Y25,Y30,Y30BH,Y35,C1,C5,C8,C8B,C9,C10,C11 and so on.
Supply OEM Customized Sizes
Standard tolerance for ceramic magnets is + or – 2% of the dimension except thickness. The tolerance for the thickness is + or – 0.15mm.

Applications of Ferrite Rings –
Ring magnets are made specifically for loudspeaker systems and their sizes have evolved with demand from this market. However, they are also commonly used in magnetic rollers for separating applications and in the printing industry. They are also a vital component found in fast running conveyor systems in many manufacturing plants dealing with ferrous material.
