Taper bore bolt-on hubs, also known as taper lock hubs, are mechanical components used in power transmission systems to secure rotating shafts to various driven equipment such as pulleys, sprockets, and gears. These hubs provide a strong and reliable connection between the shaft and the driven component.

The main feature of taper bore bolt-on hubs is the tapered bore that allows for easy installation and removal. The hub has an inner diameter with a tapered shape that matches the corresponding tapered outer surface of the shaft. To install the hub, it is slid onto the shaft and then tightened in place using screws or bolts. As the screws are tightened, the hub is pulled inward, creating a tight fit between the hub and the shaft.

Taper bore bolt-on hubs are versatile hubs that can be used in a variety of applications. They are commonly used in fans, pumps, and other machinery where rotating parts need to be securely connected to a shaft.
