INTRODUCTION

Features

Complete Freewheels FA with lever arm are sprag freewheels with sleeve bearings. They are grease-lubricated and therefore maintenancefree.

The freewheels FA are used as:

➧Backstops

➧Indexing Freewheels

for applications with low speed freewheeling operation when used as a backstop or with a low to medium total number of actuations when used as an indexing freewheel.

In addition the standard type, two other types are available for extended service life and indexing accuracy.

Nominal torques up to 2 500 Nm.

Bores up to 85 mm.

Application example

Complete Freewheel FA 82 SFP as an indexing freewheel for the material feed of a punch. The freewheel is driven by a bell crank. The type with P-grinding does not just give the freewheel an increased service life, but also an increased indexing accuracy.

Mounting
When used as a backstop, the backdriving tor-
que is supported by the lever arm. The lever arm
must not be clamped into position. It must have
0,5 to 2 mm play in the axial and radial directi-
ons.
When used as an indexing freewheel, the lever
arm serves as the indexing lever.
The lever arm is not heat treated enabling the
customer to provide their own holes.
The tolerance of the shaft must be ISO h6 or j6.
