Product Precautions
[Caution on Product Characteristics]  ①The allowable torques are calculated based on “The surface strength of Spline” .
 ②It is essential to apply lubricant on contact surface of the spline shaft and the hub. To prevent scuffing, it is recommended to apply lubricating grease. If used in applications where oil contamination is not desirable, solid lubrication is recommended.
