Industrial Atra-Flex Coupling A2 Hub 1.4375 Coupling

Industrial Atra-Flex Coupling with an A2 hub and a 1.4375 dimension is a flexible shaft coupling designed for industrial drive systems. The A2 hub designation identifies the hub style within the Atra-Flex family, and the 1.4375 figure notes a key size parameter used for matching with compatible shafts. This coupling connects two shafts to transmit rotary motion while accommodating minor misalignment and reducing vibration transmission. The Atra-Flex line emphasizes a compact form factor and compatibility with common drive configurations, making it suitable for installations where space is limited and precise alignment is required. In catalogs, this part is identified by the combination of branding (Atra-Flex), hub spec (A2), and size (1.4375), enabling engineers and buyers to verify fit against existing drive assemblies. The clear labeling of A2 hub and 1.4375 sizing facilitates cross-reference with drawings and BOMs during installation or replacement.
