Reducers
1. Standard ball screw ComDRIVE reducers are lubricated before leaving the factory.
The standard lubrication used in the reducers is AGMA 7 Compounded oil (ISO Grade
460).
2. The products listed below are recommended by the lubricant manufacturers to meet
the requirements for normal operation. The listing of brand names is solely for the
convenience of users of Joyce equipment and their lubricant suppliers; it does not
constitute any endorsement. Joyce/Dayton assumes no responsibilities for the
quality, performance or availability of any listed products.
COMPANY BRAND NAME
Mobil Oil. ……………………….Mobil 600W Cylinder Oil
Mobil Oil….………………….….Mobil 85W100
3. Synthetic lubricants are also recommended, especially under severe service. These
lubricants are more viscosity/temperature stable and provide service over a broad
range of temperatures. These lubricants have a longer service life, require fewer oil
changes and increase the life of the gearbox by reducing friction and wear. This
lubricant is also compatible with nitrile seal material and alloy bronze gear material.

4. The oil in the reducer must be maintained at the proper level. The reducer must be at
rest when the oil level is checked.
5. In a new unit, the oil should be changed (or filtered) after four weeks (or 100 hours) of
use. The case should be flushed with light oil to remove any foreign substances.
6. After the initial oil change, the oil should be changed once every 6 months or 2500
hours, whichever occurs first.
7. More frequent oil changes may be necessary when there are severe duty or dirty
conditions present.
8. Special order speed reducers supplied with ComDRIVE® actuators may or may not
be factory lubricated. In this case, a separate O&M can be provided for the special
reducer.
