Complete Freewheels FBF
with mounting flange
with sprags, available in five types
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.
Mounting
The customer attachment part is centered on the external diameter D and then bolted on to
the face via the flange. 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 FBF 72, type with sprag lift-off Z and 38 mm bore:
• FBF 72 LZ, d = 38 mm
When ordering, please also specify the free - wheeling direction of the inner ring when view -
ed in direction X:
• counterclockwise free or
