SKF Taper Bush, 100mm Bore Size, 127mm Length - PHF TB5050X100MM

This taper bush provides a secure mechanical fastening solution for mounting components onto shafts in industrial settings. It is intended to produce a concentric fit between a hub and a shaft, allowing accurate torque transmission and straightforward assembly in automation, electrical and mechanical equipment.

Features and Benefits:

• Cast iron construction for sustained load-bearing capacity
• 100mm internal bore for compatibility with standard shaft sizes
• 127mm axial length to ensure stable axial positioning
• 178mm external diameter for robust hub engagement
• Tapered profile enabling controlled shrink-fit between parts

Applications

• Suitable for mounting pulleys in conveyor drive systems
• Ideal for coupling hubs in industrial gearboxes
• Used with motor shafts in automation lines
• Can be used for retrofitting rotating assemblies in manufacturing equipment

How does the component achieve a secure fit on the shaft?

The tapered geometry generates radial expansion against the shaft when the bush is driven into the mating hub, creating frictional contact that transmits torque without additional machining.

Which material characteristics affect its wear performance?

The grey cast iron composition offers hardness and damping properties that resist surface fatigue and reduce vibration during continuous operation.

What should be considered when replacing an existing sleeve?

Verify outer hub bore clearance and shaft diameter match the specified internal and external dimensions to avoid misalignment during installation.

How does the length influence axial stability in assemblies?

A longer axial engagement distributes load over a greater contact area, reducing stress concentrations and helping maintain concentricity under side loads.
