Product Description

Fb440 Complete Freewheels/Backstops with Sprags for Bolting to The Face
 
Product Description
Features
Complete Freewheels FB are sealed sprag freewheels with ball bearings. They are supplied
oil-filled and ready for installation. The freewheels FB 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 areavailable.
Application example
Two Complete Freewheels FB 82 SFT as overrunning clutches in the drive of an edge trimming shear in a wide strip roll train. When trimming the edges of the strip, the trimming
rollers are driven by the drive of the edge trimming shear. By doing so, the two freewheels work in driving operation. As soon as the sheet they pull the strip at an increased speed and the inner rings overrun the slower turning drive of the edge trimming shear. By doing so, the
freewheels work in freewheeling operation. The RIDUVIT sprags lend the freewheels an extended service life.
