Chapter 6 Filling the Lubricant

6.2.2. Vertical shaft installation



For the E series and original series

The amount of lubricant the reduction gear requires and the target range (the

areas in the

diagram) when the reduction gear is installed in the vertical shaft are indicated in Fig. 6-3. Each amount
does not include the space (the

areas in the diagram) on the motor mounting side. Therefore, if

there is a blank space, also fill the space. Leave a space about 10% of the total volume of the internal
capacity of the reduction gear (the

areas in the diagram) and the space on the motor mounting

side (the

areas in the diagram). For the amount of lubricant for the products not included in the

catalog, contact our service representative individually.
