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
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
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
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
