Help Identify

This part is one half of a flexible shaft coupling, likely from the TB Wood’s Sure-Flex® or a similar style industrial coupling system. These couplings are used to connect two rotating shafts, typically between a motor and a driven component such as a gearbox, pump, or conveyor, while allowing for slight misalignment and absorbing shock or vibration. The component shown is a single coupling flange and is incomplete without its elastomeric sleeve (spider insert) and matching flange. It cannot function alone and would either need to be paired with its corresponding parts or sold as a replacement piece. To accurately identify the exact part number or model, the bore size and keyway dimensions are critical: they determine compatibility with specific shaft sizes and are required for an exact match in catalog listings. This kind of coupling is common in industrial, agricultural, and manufacturing equipment, not in automotive or military use.
