02250178-942 Sullair OEM Split Taper Lock Bushing | Precision Shaft Mounting Component

The 02250178-942 Sullair OEM Split Taper Lock Bushing is a precision-engineered shaft mounting component used to secure rotating elements such as hubs, flanges, sprockets, or rigid coupler components onto a shaft. Unlike flexible couplers, this component performs a rigid mechanical locking function, ensuring accurate alignment and dependable torque transfer between the shaft and mounted component.

Split taper lock bushings are widely used in compressor drive systems, industrial machinery, generators, and power transmission assemblies due to their reliability and ease of installation. The 250035-375 bushing is manufactured to OEM dimensional and material standards to ensure proper fitment, secure clamping force, and consistent performance under load.

This bushing is designed for applications where precise shaft engagement and repeatable alignment are critical.

Key Features and Benefits

• OEM Split Taper Lock Bushing – Manufactured to original equipment dimensional specifications

• Split Taper Design – Provides uniform clamping pressure and high holding torque

• Precision Machined – Ensures concentric alignment between shaft and mounted component

• High Torque Capacity – Suitable for industrial power transmission applications

• Secure Shaft Engagement – Prevents slippage under load

• Service-Friendly Installation – Allows for controlled installation and removal

Functional Design and Performance

The 02250178-942 split taper lock bushing functions by drawing the tapered outer surface of the bushing into a matching tapered hub bore as mounting screws are tightened. This action creates a powerful mechanical grip on the shaft through radial compression, resulting in a secure, backlash-free connection.

The split design allows the bushing to compress evenly around the shaft circumference, ensuring excellent concentricity and minimizing runout. This is especially important in compressor drive systems and rotating assemblies where imbalance or misalignment can lead to vibration, bearing wear, and premature component failure.

Because the bushing relies on mechanical interference rather than elastomeric flexibility, it provides rigid torque transmission while maintaining accurate shaft positioning.

Applications and Compatibility

The 02250178-942 OEM Split Taper Lock Bushing is commonly used in:

• Industrial compressor drive assemblies

• Rigid coupler hubs and flanges

• Pulleys, sheaves, and sprockets

• Generator and motor drive systems

• Industrial power transmission equipment

This bushing is intended for use where a shaft interface is specified and should be paired with a compatible tapered hub or flange designed for split taper lock bushings.

Technical Specifications

• Part Number: 02250178-942

• Component Type: Split taper lock bushing

• Design: Split taper locking configuration

• Material: High-strength steel

• Function: Rigid shaft mounting and torque transmission

Installation and Service Considerations

Proper installation of the 02250178-942 split taper lock bushing is critical to achieving full holding strength and concentric alignment. Mounting surfaces should be clean and free of debris, and fasteners should be tightened evenly according to recommended torque values.

When removal is required, the split taper design allows controlled disengagement without damaging the shaft or hub, supporting efficient maintenance and component replacement.
