Part of the L090 series, this hub accepts a minimum bore diameter of 0.25 inches and a maximum bore diameter of approximately 0.55 inches (14.00 mm), with an outside diameter of 2.11 inches and an overall length of 2.12 inches. It is rated for up to 144 inch-pounds (16.30 N\/m) of torque. Licensed HVAC, mechanical, and industrial service technicians regularly install these hubs in pump, fan, and motor drive applications where vibration dampening and misalignment tolerance are required.\u003c\/p\u003e\n\u003cp\u003eThis hub is intended for use in flexible jaw coupling assemblies in light-to-medium industrial and mechanical systems. A complete coupling requires two hubs and one spider insert, ordered separately. Typical applications include pump-to-motor connections, blower drive shafts, and similar rotating equipment found in HVAC mechanical rooms, plumbing pump systems, and general industrial machinery. The L090 series designation ensures compatibility with other L090-rated components from the same coupling family.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSintered iron construction for durability in rotating drive applications\u003c\/li\u003e\n  \u003cli\u003eL090 series coupling size code for straightforward replacement sourcing\u003c\/li\u003e\n  \u003cli\u003eRated to 144 inch-pounds of torque for light-to-medium duty loads\u003c\/li\u003e\n  \u003cli\u003eMinimum bore of 0.25 inches with maximum bore capacity up to 14.00 mm\u003c\/li\u003e\n  \u003cli\u003eOutside diameter of 2.11 inches and overall length of 2.12 inches for compact fitment\u003c\/li\u003e\n  \u003cli\u003eSold individually — two hubs plus one spider required for a complete coupling assembly\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct L090 series jaw coupling hub.
