Taper Lock

Working Principle

A taper lock is a mechanical fastener used in a variety of machinery and equipment to securely connect two components, usually hubs and shafts & is designed to optimize torque flow and facilitate assembly and disassembly.


Here are the key characteristics of Taper Locks:

  • 1. Tapered Design for Interference Fit: Taper Locks have a tapered shape that creates an interference fit when the hub and shaft are pressed together. This design ensures a secure and friction-based connection, allowing for efficient torque transmission.
  • 2. Easy Installation and Reusability: Taper Locks are relatively easy to install using simple tools like a wrench. Additionally, they can be assembled and disassembled multiple times without compromising their performance, making them suitable for applications that require frequent adjustments or maintenance.


  • High Torque Transmission: Taper Locks provide a robust and secure connection between rotating components and shafts, making them suitable for applications with high torque requirements.
  • Easy Installation: Installing and removing Taper Lock components is relatively straightforward and can be done without specialized tools. This ease of installation reduces downtime during maintenance or component replacement.
  • Adjustability: Taper Lock systems offer some degree of adjustability. You can reposition the component on the shaft or replace it with another Taper Lock component to accommodate different shaft sizes or adapt to changing requirements.
  • Cost-Effective: Taper Locks are cost-effective due to their durability and ease of maintenance. They reduce the need for complex machining or welding to secure components to shafts.
