The DODGE 121991 Taper-Lock Bushing is an essential high-precision component designed for secure, concentric mounting of sheaves, sprockets, and pulleys onto shafts in demanding industrial environments. Precision-machined to ensure minimal runout and maximum torque transfer, this bushing features a 1.716-inch bore and is specifically engineered for robust compatibility with 2BK 110 V-belt sheaves. The Taper-Lock design utilizes a high-strength key and set screws (provided) to create a powerful interference fit, eliminating slippage and maximizing the lifespan of the entire drive system under heavy shock loads and continuous operation. Constructed from high-grade materials, the 121991 bushing provides the foundational stability required for reliable power transmission.
Choosing DODGE Taper-Lock bushings minimizes critical downtime through superior design focused on rapid installation and removal. Unlike conventional fixed bore couplings, the Taper-Lock system allows maintenance personnel to quickly replace drive components without damaging the shaft or requiring specialized extraction tools. This superior design choice translates directly into a reduced Total Cost of Ownership (TCO) and enhanced operational efficiency. Trust the proven quality and decades of reliability built into every DODGE product, ensuring your V-belt drive systems operate flawlessly even in the most challenging manufacturing, aggregate, or HVAC applications.
