Constraints
The freewheel clutch insert element requires axial constraints
on both sides.
Connecting parts
Hardening and grinding of the mating parts is necessary.
Chamfered shafts and hubs ease installation
(Pg. 58).
Bearing
Freewheel clutch insert elements are not self-centering.
External bearing support to define the gap between mating parts
(Shaft and housing) is necessary.

Applications
:
Backstop
A Backstop application is where rotation
is allowed in one direction and stopped in
the opposite.
Application examples:
· Conveyor equipment
· Mixers
· High voltage switches
· Furniture industry
· Turnstiles and revolving doors
· Geared motors
· Winches
· Elevators
· Cranes
· Strap/belt tighteners
· Bucket conveyors
· Belt reversing locks
· Fans
· Automatic doors (subway)
· Fire damper flaps
· Aviation technology
· Roller plants
· Summer skiing
Indexing clutch
A repeated drive then idle motion will
be transferred to the driven side, step by
step, as rotary motion in one direction (the
clamping direction).
Application examples:
·Paper processing (advance)
· Seeding machines
· Staplers (staples)
· Conveyor belts (drive)
· Ratchets
· Ratchet wrenches
· Roller advance
· Installation tools
· Automation technology
Overrunning clutch
If the speed of the driven side exceeds the
speed of the driving side,the freewheel-clutch disengages the driving and driven sides by switching from torque transimit to idle.
Application examples:
·Copier machines
·
Printing machines
· Conveyor equipment
· Transport equipment (speed matching)
· Starters for combustion engines
· Ergometers
· E-bikes
· Bicycle hubs
· Starters
· Emergency power aggregates
· Generators
· Hybrid applications (E-mobility)
· Palletizing and storage systems
· Model helicopters
· Hand operated sirens
· Roller coasters
· Washing systems
· Continuous ovens
· Compressors
· Compensating gearboxes
· Gas turbine drives
· Pump drives
· Belt drives
· Wheelchairs
