Jaw Couplings

Jaw couplings are versatile and reliable components used in mechanical power transmission systems to connect two shafts while compensating for misalignments and absorbing shock loads. Characterized by their simple yet effective design, jaw couplings consist of two hubs with interlocking teeth and an elastomeric spider insert. This spider insert acts as a flexible element, transmitting torque between the hubs while damping vibrations and reducing noise. The hubs are typically made of steel or aluminum for strength and durability, while the spider insert is composed of materials such as polyurethane or rubber for flexibility and resilience. Jaw couplings excel in various industrial applications, including pumps, fans, and compressors, where they provide smooth and efficient power transmission while protecting machinery from excessive loads and shaft misalignments. With their easy installation, minimal maintenance requirements, and ability to withstand harsh operating conditions, jaw couplings are essential components for ensuring the reliability and performance of rotating equipment in diverse industrial settings.
