Application Notes

1. Refer to recommended housing tolerances and component set drawing for proper installation specifications.
2. Use the recommended lubricants and proper quantity. Replace the lubricant at the recommended service interval.
3. There are four areas within the gear that require lubrication.
   • A) Wave Generator Bearing
   • B) Oldham Coupling (if one is included)
   • C) Gear Teeth
   • D) Inner diameter of Flexspline
4. The Wave Generator must be securely fastened to the input hub to prevent axial movement along the input shaft.
5. The Wave Generator must be assembled concentrically with the Circular Spline to prevent an improper assembly. Refer to the section named "Dedoidal" in our catalog.
6. The surface to which the Circular Spline is clamped, must be clean, flat, and free of debris or burrs. Tighten screws using a torque wrench and use no other locking hardware except the suitable grade Loctite sealant or equivalent.
7. The part numbering method is as follows (space permitting).
   SS XX JJJJJJ Q

   SS: Size
   XX: Ratio
   JJJJJJ: Serial Number
   Q: Set Number

   In order to obtain the published performance specifications, it is essential that the component set remains as a matched set. Each component within the component set must have the same part number, including the set number. The above number may be required for ordering replacement drives.
8. Proper seals, gaskets, or sealants must be used to contain the small amount of oil that may separate from the grease.
9. The Component Set has been coated with a rust preventative oil for storage purposes, and must be thoroughly cleaned prior to use.
10. There are two types of component sets: Cup-Type and Pancake-Type.

The Cup-Type has a Flexspline that is shaped like a cup.

The Pancake-Type has a Flexspline that is a thin sleeve with gearteeth on the outside diameter. The Pancake-Type has an additional item called a Dynamic Spline, which appears to be similar to the Circular Spline. The Dynamic Spline has larger chamfers than the Circular Spline. These two items are not interchangeable.
