(i)Remark

  • The positional relationship between the spline nut key or mounting hole and additional machining cannot be specified. The additional machining position displayed in the 3D preview is an example and differs from the actual machining position. If you need to specify the machining position, we will estimate it as a non-standard product.
  • Please check the content on our website as the PDF does not contain the most up-to-date information.
