Falk / Rexnord-published interchange row · Verify motor speed and installed ratio · Published size reference Ultramite size 08
Falk/Rexnord Form 950-501 publishes 08UCBN2 in its base-mounted helical dimensional comparison for size 08. The guide states that several competitive helical designs are drop-in replacements but instructs users to verify motor speed, gear ratio, output RPM, mounting position and current catalog ratings. Availability of this historical configuration should also be confirmed.
The manufacturer publishes the two models in a dimensional-interchange table or equivalent dimensional comparison.
Falk / Rexnord identifies 08UCBN2 as the target in this published source row · Verify motor speed and installed ratio · Ultramite size 08.
Dimensional alignment does not by itself prove identical torque, thermal rating, service factor, ratio, accessories, or application suitability.
Accessories, bushings, motor mounts, backstops, shafts, screw-conveyor components, and application duty still need to be checked individually.
