Product information

INTRODUCTION

Features

Complete Freewheels FBF with mounting

flange are sealed sprag freewheels with ball

bearings. They are supplied oil-filled and ready

for installation.

The freewheels FBF are used as:

➧ Backstops

➧ Overrunning Clutches

➧ Indexing Freewheels

In addition to the standard type, four other

types are available for extended service life and

indexing accuracy.

Nominal torques up to 160 000 Nm.

Bores up to 300 mm. Many standard bores are

available.

Application example

Complete Freewheel FBF 72 DX as an overrunning clutch in the drive of a meat processing machine (chopper). During the mixing process, the gear motor drives the bowl via the gear wheel drive and simultaneously the knife shaft via the belt drive and the locked freewheel. In the cutting process, the knife shaft is driven by a second motor at high speed. By doing so, the inner ring overruns the outer ring that is driven by the gear motor and the gear motor is automatically disengaged. With the high speed of the inner ring in freewheeling operation, the type sprag lift-off X is used; the sprags work in freewheeling operation without contact and hence are wear-free.
