What are the standard input speeds?
In general terms, the speeds are 1750 and 1165 RPM. The selection tables in our catalog are based on 1750 RPM. When other input speeds are used, the horsepower and torque ratings will vary.
How often do I change the oil?
The first oil change should be carried out preferably after 100 hours and not more than 800 hours of operation. The removed oil may be used again after filtering. Filter the oil volume at least 10 times using a 10mm filter or smaller. Subsequently the oil should be renewed after 4000 to 8000 hours or maximum of 18 months of operation depending on working conditions. Please refer to service manual for detailed oil change instructions.
What type of lubrication should be used?
Mineral oils containing EP additives, which increase oil film load capacity should be used. Refer to the P4 service manual for recommended oil types.
How can I be sure that the reducer can withstand periodic excessive overloads?
Cyclo® BBB5 Speed Reducers provide 300% momentary intermittent shock load capacity. For applications with shock loads greater than 300%, consult a Sumitomo Application Engineer.
What do I do if my application has particularly severe operating conditions?
The standard ratings for Cyclo® BBB5 are based on 10-hour daily service under conditions of uniform loads (equivalent to AGMA service factor 1.0). By following the product selection process outlined in our catalog, you will determine and apply the Service Factors to compensate for the severe operating conditions. Sumitomo recommend our Cyclo® BBB4 product for extremely severe operating conditions, as it is a more robust right-angle gearbox design.
