Disengaging
When the outer ring is rotating the centrifugal force causes the
sprags to lift off from the inner
race. This reduces wear during freewheeling operation.
Engaging
When the outer ring is rotating the centrifugal force presses the
sprags against the inner ring.
This enhances the ability of the sprags to engage immediately when
torque is applied.
Drag strips
To reduce wear during freewheeling operation between sprags and the
inner race, drag strips
made from wear-resistant beryllium copper alloy are attached to the
inner cage. This results in increased friction between inner cage
and inner race. This counteracts individual sprag activation during
freewheeling operation, thereby greatly reducing sprag pressure on
the inner race.
Brake clips
Some freewheel sizes are available with brake clips fitted on the
outer cage to prevent further
automatic rotation of the Cage Freewheel during rapid acceleration
and deceleration of
Type DC BWC BWX is a sprag type freewheel cage without inner or
outer races. It must be installed in a design providing races,
bearing support for axial and radial loads, lubrication and
sealing.

Company Information
Changzhou RenBen Bearing Factory(Changzhou Global Bearing Factory)is a manufacturer specialized in Producing Various cam clutch, one way bearing, needle roller bearings,one way clutch, backstop clutch, overrunning clutch and other bearings with high technology.
Workshop
Application Industry:
Main products
1. One Way Bearing
1. Overrunning clutch
for multiple-machine drives or to separate the iner-tia of masses of a driven machine from the driving machine after it has been switched off.
2. Indexing clutch
which turns a shaft step by step, thus achieving indexed material feed or a variable speed.
3. Backstop
to prevent a machine shaft turning backwards. In this case the overrunning clutch acts as a brake
2.Needle roller bearings
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
