Note:
1. The Decelerator inertia is the Servomotor shaft conversion value.
2. The protective structure rating of the Servomotor combined with the Decelerator is IP44. (Excluding decelerator and servo motor connecting parts.)
3. The Allowable radial load column shows the values obtained at the center of the shaft (T/2).

R88M-1[] / R88D-1SN[]-ECT Specifications 67

4. The standard shaft type is a shaft with key and tap. (The key is temporarily assembled to the shaft.)
5. Take care so that the surface temperature of the Decelerator does not exceed 90°C.
