We consider the operating environment and application to help you select the most suitable “magnetization method,” “shape,” and “magnet type.” Please feel free to contact us.
Magnetization Method
※ Special magnetization methods may require an additional magnetizing yoke fee (initial cost).
Shape
About SI and CGS Units
“SI” refers to the International System of Units (Système International d’Unités). This system internationally standardized the many different units that had previously caused confusion.
Today, SI serves as a common worldwide and rational system of measurement. However, the traditional CGS system also remains widely used. Therefore, both unit systems continue to appear in practical applications.
- Dimensional tolerances depend on the dimensions and shape, but they are generally approximately ±0.1 to ±0.2. Higher accuracy is also available, so please specify your requirements when necessary.
- We also welcome orders for special or custom-made products. Please feel free to contact us regarding small-lot production.
※ Please contact us for current stock availability.
※ We also stock many products other than the standard specifications.
※ Depending on the dimensions, some products may require a longer lead time.
