FSO Series Sprag Clutch Backstop One Way Bearing

Feature

Types FSO, FSO-GR, and HPI 300 to 700 are sprag type freewheels self-contained , sealed and bearing supported, using two ball bearings.

Units are delivered oil or grease lubricated according to the type. It is a Formsprag USA design

with a »full sprag complement« that gives a very high torque for a given diameter. Any overload is

resisted by a sprag to sprag abutment, avoiding a sprag tilt over. Types FSO and HPI are oil lubricated and use standard shaft lip seals. Type FSO-GR is grease lubricated and can be equipped with contact free labyrinth seals. Type HPI is specially designed for high speed indexing applications.
