COMPONENT APPLICATION
Strain-wave reducer grease: tooth contacts & bearings
Distinguish flexspline/circular-spline tooth contacts from the wave-generator bearing. Review specified materials, application points and quantity, operating torque, temperature and durability.
Application points & evaluation
Wave-generator bearing
Compare torque, speed and temperature rise.
Assembly & grease locations
Match the specified application locations, quantity and seals.

SELECTION IN CONTEXT
Do the teeth and bearing share the same lubrication conditions?
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.
Match the contact, condition and evidence
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 |
How to compare candidates
Read the exact model documentation
Record the specified material, points, quantity and use conditions for the teeth and bearing separately.
Control assembly and filling
Control residues, cleaning, orientation and quantity, then define load, speed and temperature conditions.
Review operation and post-durability condition
Record starting/running torque, heat, sound, leakage and contact surfaces.
Application questions
Can the same grease as an RV reducer be used?
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.
How much should be applied to the teeth and bearing?
There is no universal quantity. Model, size, orientation and application point affect the specification; use the quantity and procedure in the relevant documentation.
Is lower torque enough for selection?
Compare tooth/bearing durability, heat, sound and sealing alongside torque, including the changeover from the current lubricant.
MATERIALS & GRADES
Materials & grades to review
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.
