It is designed to connect rotating shafts in industrial power transmission applications, accommodating minor misalignment while transmitting torque between coupled components. With an overall length of 3.4375 inches and an outside diameter of 8.625 inches, this size 11 flange accepts a 1.25-inch bore. Mechanical contractors, millwrights, and industrial maintenance technicians install this style of coupling in pump, compressor, conveyor, and general drive train setups where a bolted flange interface is required.\u003c\/p\u003e\u003cp\u003eThe 11SMPB is suited for industrial and commercial mechanical drive applications where a cast iron flange coupling is specified. The Type S designation identifies its flange style within the TB WOOD'S coupling line. It is typically installed on pump and motor shafts in fixed-speed drive systems across manufacturing, HVAC mechanical rooms, and process equipment installations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCast iron construction provides durability in industrial power transmission environments\u003c\/li\u003e\n\u003cli\u003eSize 11 coupling with 1.25-inch bore diameter for shaft fitment\u003c\/li\u003e\n\u003cli\u003eOverall length of 3.4375 inches with an 8.625-inch outside hub diameter\u003c\/li\u003e\n\u003cli\u003eBore depth of 3.438 inches accommodates full shaft engagement\u003c\/li\u003e\n\u003cli\u003eType S flange style for compatibility within the TB WOOD'S flexible coupling system\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit flange coupling for industrial and commercial power transmission drive systems requiring a size 11 cast iron flexible flange component.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by a millwright or licensed mechanical technician. Disconnect and lock out all power to the drive system before handling any coupling components. Ensure shaft and bore surfaces are clean and within tolerance before pressing or fitting the flange.
