Reduction gear efficiency
(Note 5)
85 to 94% 80 to 90%
Note 1. The above values are typical values and not guaranteed values.
2. For grease lubrication, the reduction gear is already grease-packed.
3. If the above indicated value is exceeded, please consult us.
4. Maintenance-free.
5. The reduction gear efficiency differs depending on the reduction ratio.
Also, it changes depending on the use conditions such as the output torque, speed and rotation, temperature, etc. The
numerical value in the table is a typical value in the rated torque, rated speed and rotation and typical temperature, and
not a guaranteed value.
(a) Lubrication of reduction gears for general industrial machines
Oil lubrication cannot be used in applications where the servo motor will move. Specify grease
lubrication.
For grease lubrication, the reduction gear is already grease-packed.
For oil lubrication, pack the reduction gear with oil on the customer side.
