1) Nominal Motor HP is the highest HP 1800 rpm motor to be used with the gearbox under conditions of 1.0 service factor.
Gearbox input power capacity decreases as motor speed decreases and as service factor increases.
2) OHL= Overhung Load ratings are for forces perpendicular to the output shaft and located at the shaft midpoint, such as from
a gear, pulley, or sprocket with a belt or chain. Divide OHL ratings by the applicable OHL K factors shown separately in the
Selection Factors tables. OHL ratings should also be divided by applicable service factors.
3) Maximum Mechanical Ratings are limits based on strength and durability of gearbox components; applicable when operating
time is short and stopped time is greater than or equal to operating time. These ratings are applicable for 1.0 service factor
loads, and may require modification depending upon characteristics of the applicable driven loads. Refer to the “Service
Factors” table for more information.
