NR772 is the two-stage flange-mounted N77 model with a 90 mm output shaft. A large coupling or gear can introduce forces in addition to torque. Define its position along the 170 mm shaft so application loads can be compared correctly with the manufacturer's limits.
Selection for your machine
Provide output-component diameter, mass and distance from the flange face.

This is a base model record. Select ratio, motor or input interface and mounting position when ordering. Housing torque is a reference, not a guaranteed configured output. Price, stock and lead time require confirmation.
Does adequate torque capacity also confirm shaft loading?
No. Radial and axial forces and their application points require separate checks.
