no friction, non-contact.
Non-contact transmission products are parts that utilize magnetic force to transmit motion without the need for physical contact. Rotation is generated by harnessing the two forces of attraction and repulsion resulting from the magnetic force of a strong magnet. The use of contactless transmission components allows for smooth power transmission in applications that require ultra-low noise levels and minimal particle generation. Additionally, contactless transmission is effective in preventing cogging and reducing damage during operation. These components also support a wide range of eccentric center and eccentric angle values for installation, making removal and centering processes straightforward. They are particularly suitable for environments such as cleanrooms, food processing machines, and pumps, where cleanliness must be preserved. Many types of these components employ permanent magnets, which have a long lifespan. Furthermore, many are designed for outdoor use. Common materials used include metal, and the heat resistance temperature varies depending on the material’s properties.
Disc type magnetic couplings consist of two opposing discs equipped with powerful rare earth magnets. The torque applied to one disc is transmitted through an air gap to the other disc. Due to its simple, flat design, it allows for angular misalignment of up to 3º or parallel misalignment up to 6.35mm, yet still transmits almost the full rotational torque. Additionally, an inexpensive flat barrier can be fabricated to separate the atmospheres or fluids surrounding the two discs. Typical applications encompass magnetic mixers and magnetic drive pumps.

The magnetic pole of a bevel gear mesh with the pole of a mating bevel gear, forming a magnetic bevel gear pair. They are a type of machine element commonly found in applications that require a change in direction and speed.Bevel gears are used with bevel pinions to create mechanical systems that change speed and torque primarily in perpendicular shaft applications.They have different transmission ratios to choose from. Common transmission ratios are: 1:1, 2:1, 4:3, 5:4. In addition, CCmagnetics accepts customized orders for Magnetic bevel gears.

Cross-type magnetic gears, also known as magnetic miter gears, are essentially the same as magnetic bevel gears, functioning with a 90-degree drive. The primary distinction is that in cross-type magnetic gears, both gears are of equal size, resulting in a fixed magnetic transmission ratio of 1:1. To facilitate this type of transmission, the magnetic poles of the cross-type magnetic gears are designed with an inclination. In addition, cross-type magnetic gears can convey less torque than parallel type magnets gears of the same size.
The parallel-type magnetic gears consist of two magnetic gears. Their magnetic poles are in parallel and correspond with each other. Contactless magnetic transmission is achieved through magnetic attraction. The transmission torque of the parallel-type magnetic gears is stronger than that of the cross-type magnetic gears because the parallel-type magnetic gears run parallel and have a larger contact area between their magnetic poles. According to different needs, all magnetic transmission products can be customized into PVC, aluminum alloy, titanium, and stainless steel materials.
The magnetic coupling transmit the torque without contact through magnetic forces between the internal and external rotor. They ensure hermetic separation between driving and driven side in pumps and agitators sealing hazardous liquids and gases reliably.
We can customize the magnetic coupler into sus304 (uns s30400), 316ti (uns s31635), sus431(uns s43100), ti-6al-4v (uns r56400).
The magnetic rack and pinion gears/couplings consists of a magnetic gear/coupling and an additional track made of square magnets. They are commonly used in medical and chemical fields. For example: Reagents require stirring, shaking and reciprocating motion. Its working process produces no noise, requires no oil, no maintenance, and is simple to install. They are available in two types of magnetic transmission: Cross type and parallel type.
