When Spline Shaft ④ is configured, the surface will be light yellow, and there may be a color difference.
  Due to the surface treatment process, the following parts are more susceptible to rust.
  -Cut section
  -Groove part
  -Cut section
  -Tapped part
The relative positions of the grooves of Spline Shaft, the keyways and oil holes of nuts, and all the alterations (wrench flat, set screw flat, etc.) in the 3D model arefor reference only and may differ from their actual positions.

■Precautions for Selection and Use of Spline Shaft
1. The relative positions of the grooves of Spline Shaft, the keyways and oil holes of straight nuts, and all the alterations (wrench flat, set screw flat, etc.) in the 3D model are for reference only and may differ from their actualpositions.
2. When re-inserting a nut into the Spline Shaft, be sure to insert it horizontally, otherwise the ball will fall off.
3. As resin parts are used inside the nuts, please use them at temperatures below 80℃.
4. Although the nuts are greased on the inside before leaving the factory, please re-grease them every 2~3 months or every 50km of traveling distance after receipt of the goods, otherwise their use will be impaired.
5. No guarantee is given for the noise level of this product.
6. No guarantee is given that the Spline Shaft or nuts of this product will fall freely.
7. This product is a machined type, so there will be knife patterns and color difference in its appearance. It is normal for the product to have some scratches or color changes. Please feel free to use.
8. The Spline Shaft is quenched, and annealed during machining.
  Due to the annealing treatment, the hardness of the machined part + area about 15 mm before and after the part may be reduced (see the following example). And the annealed section is out of the guaranteed range of outerdiameter dimensional tolerance.
  Subtract the size of the annealed section when calculating the stroke.
