Flexspline & tooth contacts
Review cyclic flexing, load and tooth-contact wear.

COMPONENT APPLICATION
Distinguish flexspline/circular-spline tooth contacts from the wave-generator bearing. Review specified materials, application points and quantity, operating torque, temperature and durability.

Review cyclic flexing, load and tooth-contact wear.
Compare torque, speed and temperature rise.
Match the specified application locations, quantity and seals.
SELECTION IN CONTEXT
A wave generator deforms the flexspline. Review tooth contacts separately from the wave-generator bearing, follow model-specific application points and quantity, and observe manufacturer-specific lubricant and no-mixing requirements.
Define the differences between contacts before comparing candidate materials.
| Contact | Selection & evaluation | Record |
|---|---|---|
| Design & specified conditions | Start with the model, orientation, load, input speed and manufacturer lubrication requirements. | Model/size, orientation, specified material and load/speed |
| Flexspline & tooth meshes | Compare tooth lubrication, load cycles, wear and abnormalities under the specified evaluation conditions. | Meshing area, torque, cycles and initial/post-durability tooth condition |
| Wave-generator bearing | Review lubricant supply, starting drag, heat during running and lubricant condition at the bearing. | Application point/dose, starting/running torque and temperature |
| Assembly, changeover & sealing | Match filling and seal requirements to the model, including residues, leakage and relubrication/replacement. | Current material, cleaning, quantity, seals and service procedure |
Record the specified material, points, quantity and use conditions for the teeth and bearing separately.
Control residues, cleaning, orientation and quantity, then define load, speed and temperature conditions.
Record starting/running torque, heat, sound, leakage and contact surfaces.
The mechanisms and specifications differ. A similar name or consistency does not establish suitability for the tooth contacts, bearing or assembly; follow the exact model documentation.
There is no universal quantity. Model, size, orientation and application point affect the specification; use the quantity and procedure in the relevant documentation.
Compare tooth/bearing durability, heat, sound and sealing alongside torque, including the changeover from the current lubricant.
MATERIALS & GRADES
The listed EUBO grades are application candidates, not reducer-manufacturer recommendations, approvals or drop-in equivalents. Review the specified lubricant and change conditions first.
Grease selection for strain-wave reducers, including the flexspline and wave-generator interfaces. Review shear behaviour and drive efficiency.

View the product family & documentation →Confirm numerical specifications and use scope in current grade-specific TDS and SDS. Share the part drawing, materials, conditions and evaluation targets.
Technical enquiry & samples →First check whether the manufacturer permits such an evaluation and which service requirements must be retained. An automation description does not establish equivalence, mixing compatibility or approval of an EUBO grade.
