COMPONENT APPLICATION
RV & cycloidal reducer grease: design, filling & evaluation
Review tooth contacts, eccentric components, bearings and seals in RV/cycloidal reducers. Compare the specified lubricant, fill quantity/orientation, torque, heat and durability on the actual design.
Application points & evaluation
Eccentric shafts & support bearings
Measure starting torque, heat and lubricant retention.
Output shaft, supports & seals
Check application points, quantity, seal compatibility and leakage.

SELECTION IN CONTEXT
What determines grease selection for an RV reducer?
Start with the reducer model and its manufacturer-specified lubricant and filling procedure. Front-stage gears, eccentric components, cycloidal discs/pins and support bearings have different contact conditions. Evaluate candidates against the actual design, load/speed, temperature and sealing rather than substituting by material name or consistency alone.
Match the contact, condition and evidence
Define the differences between contacts before comparing candidate materials.
| Contact | Selection & evaluation | Record |
|---|---|---|
| Model & specified lubricant | Use the exact manual, specified material and duty requirements; the RV/cycloidal category alone is insufficient. | Manufacturer, model, orientation, current lubricant and document revision |
| Tooth contacts, eccentrics & bearings | Control load, input speed and duty cycle when comparing lubrication, wear, sound and vibration. | Contacts, load/speed, duty cycle, initial and post-durability condition |
| Filling & sealing | Follow the specified quantity, procedure and installation orientation; review supply, overfilling and leakage. | Quantity/location, orientation, seal material, leakage and relubrication requirements |
| Start-up, temperature & durability | Separate start-up from continuous running and record temperature rise, torque and durability changes using consistent criteria. | Ambient/housing temperature, start/running torque, method and cycles |
How to compare candidates
Review the specification and current state
Record the model, lubricant/filling specification and current material, and define why a change is being considered.
Define changeover and comparison conditions
Follow manufacturer requirements for residual material, cleaning, quantity, orientation and operation.
Compare initial and post-durability operation
Record torque, temperature, sound/vibration, leakage and component condition against the agreed criteria.
Application questions
Can a strain-wave grease be used directly?
Do not transfer a lubricant specification between mechanisms. RV/cycloidal and strain-wave designs have different contacts and filling requirements; use the target reducer specification and actual-part evaluation.
Does adding more grease improve lubrication?
Use the specified quantity. Filling affects not only supply but also churning resistance, heat, pressure and leakage; follow the target reducer procedure rather than adding grease arbitrarily.
Can a candidate be added to the current grease?
Do not assume blending is acceptable. Review the specified and candidate materials, residues and cleaning/replacement procedure using the reducer and lubricant records.

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.
