    Mating parts
    Hardening and grinding of the mating parts is not necessary.
    Thoroughly clean (grease free) the mating parts in the vicinity of
    the freewheel clutch as well as the freewheel clutch's rings before
    making the press fit.
    Bearing
    The freewheel clutch includes a ball bearing.
    Additional external bearing support is not necessary.
    Press fit pressure
    Press fit pressure must not be applied to the balls.
    Clamping direction
    The arrow on the inner ring designates the inner ring's clamping
    direction.
    Seals*
    The RS Seals reliably seal out grease and dust but are not suitable
    to protect against permanent higher liquid levels.

    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
