In today’s competitive industrial environment, machinery efficiency is directly tied to productivity, cost savings, and operational reliability. Even the smallest components within a system can make a significant difference in overall performance. One such component is the jaw coupling — a mechanical device designed to transmit torque between two shafts while accommodating slight misalignments. When upgraded to high-performance variants, jaw couplings become critical contributors to enhancing machinery efficiency across industries. The Role of Jaw Couplings in Industrial Systems Jaw couplings are widely used due to their simple design, reliability, and ease of maintenance. They consist of two metal hubs with interlocking jaws and an elastomer insert (commonly referred to as the “spider”) positioned between them. This design enables the coupling to absorb shocks, dampen vibrations, and handle angular, parallel, and axial misalignments to a limited extent. While standard jaw couplin...
