RCB 081214 NSK One Way Needle Roller Clutch 12,7x19,05x22,22

RCB 081214 NSK One Way Needle Roller Clutch 12,7x19,05x22,22

RCB 081214 NSK is a drawn cup one way needle roller clutch designed for transmission systems requiring free rotation in one direction and immediate locking action in the opposite direction. The compact 12,7x19,05x22,22 mm construction is used in industrial indexing mechanisms, overrunning systems and compact drive assemblies operating under repetitive rotational cycles.

NSK RCB series one way clutches use a thin walled drawn cup outer ring together with a needle roller locking mechanism operating through automatic wedging action during reverse rotation.

The RCB 081214 model is designed for:

• one direction torque transmission
• reverse rotation prevention
• overrunning drive systems
• indexing mechanisms
• compact transmission assemblies
• industrial automation systems

The drawn cup construction provides:

• reduced radial cross section
• low rotational mass
• compact housing installation
• high torque capacity relative to size
• suitability for lightweight drive assemblies

The integrated roller and cage mechanism enables:

• rapid engagement response
• low rotational inertia
• stable operation during reversing cycles
• high switching frequency capability

According to NSK dimensional data, the RCB 081214 clutch features:

• inner diameter Fw = 12,7 mm
• outer diameter D = 19,05 mm
• width C = 22,22 mm
• torque capacity approximately 8,34 Nm
• weight approximately 16 g

RCB one way needle roller clutches are commonly installed in:

• industrial gear systems
• conveyor drives
• indexing units
• feeding mechanisms
• automation equipment
• auxiliary transmissions
• printing machinery
• compact mechanical systems

The RCB series is frequently combined with supporting needle roller bearings to provide additional shaft guidance and improve operating stability of the clutch assembly.

The phrase RCB 081214 NSK one way needle roller clutch 12,7x19,05x22,22 is frequently searched in servicing applications involving industrial overrunning systems and anti reverse transmission mechanisms.

Construction and operating characteristics

RCB 081214 NSK uses a thin wall drawn cup roller clutch construction with integrated wedging rollers.

FAQ

What does RCB mean in NSK clutch designations?

RCB indicates a drawn cup one way roller clutch designed for torque transmission in one rotational direction only.

How does a one way needle roller clutch work?

The rollers wedge between the shaft and outer ring during reverse rotation, preventing movement in the locking direction.

Can RCB 081214 NSK transmit torque in both directions?

No. The clutch transmits torque in one direction while allowing free rotation in the opposite direction.

Where are NSK one way clutches commonly used?

They are commonly used in industrial automation, conveyor systems, indexing units and feeding mechanisms.

What does drawn cup construction mean?

Drawn cup indicates a thin wall stamped outer ring providing compact radial dimensions and lightweight construction.
