This page does say
These model numbers appear together in the cited manufacturer-published cross-reference row.
Superior Gearbox identifies B063 as the target model in that published row.
The source associates the row with Match installed ratio/application and AGMA unit size VarioDrive size 063.
This page does not say
Every competitor model listed beside each other is independently certified as pairwise interchangeable.
Every installed accessory, bushing, motor mount, backstop, shaft, or screw-conveyor component will transfer unchanged.
The cross-reference removes the need to verify application torque, mounting, environment, and configuration.
