AS8 STIEBER Freewheel Clutch 8x24x8

Precision Overrunning Clutch for Industrial Drive and Backstop Applications

The AS8 STIEBER Freewheel Clutch is a precision roller-type overrunning clutch designed to transmit torque in one rotational direction while allowing free rotation in the opposite direction. Its compact dimensions of 8x24x8 mm correspond to the ISO 62 bearing series, enabling straightforward integration into industrial machinery. The AS series is intended for installations using external bearings to support radial and axial loads and is widely used in indexing systems, conveyor drives and backstop applications.

Natural entity coverage includes overrunning clutch, freewheel clutch, one way clutch, roller clutch, backstop clutch, indexing clutch, industrial clutch, torque transmission, drive system and OEM replacement.

Application in Industrial Systems

The AS8 STIEBER freewheel clutch is designed for industrial mechanisms requiring controlled one-way torque transmission.

Typical applications include:

• Conveyor systems
• Packaging machinery
• Industrial automation
• Printing machinery
• Textile machinery
• Agricultural equipment
• Indexing mechanisms
• Feed drives
• Backstop systems
• Production machinery
• OEM drive assemblies
• Material handling equipment

Its compact design makes it particularly suitable for space-limited industrial equipment.

Construction and Design

The AS8 clutch is manufactured as a roller-type overrunning clutch without integrated bearings.

Key construction features include:

• Precision roller locking mechanism
• Hardened steel races
• Compact cylindrical housing
• Keyway according to DIN 6885-1
• Press-fit outer ring (r6 tolerance)
• Oil-lubricated design
• High torsional rigidity
• ISO 62 bearing envelope dimensions

Because the AS series does not include support bearings, external bearings must absorb radial and axial loads during operation.

Material Properties

Manufactured from high-quality hardened alloy steel, the AS8 STIEBER clutch provides reliable industrial performance.

Material advantages include:

• Hardened working surfaces
• High wear resistance
• Excellent fatigue strength
• Stable dimensional accuracy
• Reliable torque transmission
• Long operating life
• Precision-machined components
• Suitable for continuous industrial duty

FAQ

What is an AS8 STIEBER freewheel clutch?

It is a roller-type overrunning clutch that transmits torque in one rotational direction while allowing free rotation in the opposite direction.

Does the AS8 include support bearings?

No. The AS series does not incorporate bearings. Separate bearings are required to support radial and axial loads.

What lubrication is recommended?

The AS8 STIEBER is designed for oil lubrication, as specified by the manufacturer.

Can the AS8 replace another AS8 freewheel clutch?

Yes. If the original unit has identical dimensions (8x24x8 mm) and matching technical specifications, the AS8 STIEBER can be used as a direct OEM replacement.
