GMN backstops with momentum lever are made of a complete unit
type FND 400 and a momentum lever. Function: For proper function
it is important to avoid any fixation of the momentum lever
because this would cause a misalignment of the inner and
outer ring of the clutch.
Backstops are able
to transmit nominal torque mounted on solid shafts. Mounted
on hollow shafts the transmittable torque decreases. In this
case please contact our technical staff to receive a calculation
on the transmittable torque in your application.
