2517B Taper Lock Adapter
The 2517B taper lock adapter is a device designed to work in conjunction with the 2517 taper lock bushing. The taper lock system is commonly used in power transmission applications to securely mount components such as pulleys, sprockets, and sheaves onto shafts.The 2517 taper lock bushing is a split, flangeless bushing with external threads. It is typically mounted onto a shaft and provides a means of mounting a compatible component. The bushing has a tapered bore that matches the taper on the adapter, ensuring a tight and secure fit.The 2517B taper lock adapter is specifically designed to fit onto the 2517 taper lock bushing. It features an internal taper that matches the taper on the bushing, allowing for easy installation and removal. The adapter is commonly used when a different component needs to be mounted onto the shaft, or when a different size or type of bushing is required.To install the 2517B taper lock adapter, the bushing is first mounted onto the shaft. The adapter is then slid onto the bushing and tightened using the provided fasteners. The tapered surfaces of the adapter and bushing create a wedging action that locks the adapter in place, providing a secure and reliable connection.
