Lubrication
Determining Lubrication Method
Sumitomo Cyclo® HBBs are shipped from the factory without lubricating oil, unless the customer specified otherwise when the
unit was ordered.
For some unit sizes and mounting configurations, the Cyclo® portion is filled at the factory with maintenance-free grease. For
these units, the Cyclo® portion does not need to be filled with lubricant before start-up. Refer to the Lubrication Method section
for details.
The unit must contain the correct type and amount of lubrication before operating.
For the Cyclo® HBB, the Cyclo® and the helical gear portions must be filled with lubricant separately and maintained separately.
Lubricant does not flow from one section to the other.
