Weld-on Hubs
The TransDrive Taper Bore Weld-On Hubs are precision-engineered components designed to provide a strong, secure, and reliable connection between rotating equipment and drive shafts. These hubs are pre-drilled, tapered, and bored to accommodate standard taper bushings, allowing for quick and easy installation while ensuring a firm grip on the shaft. The extended flange serves as a convenient and robust welding surface, enabling seamless attachment of pulleys, sprockets, fan rotors, and other driven components that require a permanent and high-strength connection.
Manufactured from durable materials to withstand demanding industrial conditions, TransDrive Weld-On Hubs offer superior torque transmission, reducing slippage and ensuring long-lasting performance. Whether used in power transmission systems, conveyor drives, or heavy-duty machinery, these hubs provide a cost-effective and efficient solution for applications that require precise alignment and enhanced mechanical strength. With TransDrive’s commitment to quality and reliability, our Weld-On Hubs help keep your equipment running smoothly and efficiently.
