Deep groove ball bearing
Product information
INTRODUCTION
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 are available.
Application example
Two Complete Freewheels FB 82 SFT as over-running clutches in the drive of an edge trim- ming 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 trim-ming shear. By doing so, the two freewheels work in driving operation. As soon as the sheet metal strip is gripped by the next pair of rollers,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 exten-ded service life.
Mounting
The customer attachment part is on the exter-nal diameter D and then bolted on to the face.The tolerance of the shaft must be ISO h6 or j6 and the tolerance of the pilot diameter D of the attachment part must be ISO H7 or J7.
Example for ordering
Freewheel size FB 72, type with sprag lift-off Z
and 38 mm bore:
• FB 72 LZ, d = 38 mm
When ordering freewheel size FB 340 and
FB440, please also specify the freewheeling di-
rection of the inner ring when viewed in
direction X:
• counterclockwise free or
• clockwise free
