TBWOODSTB8S118 TB-8S118 Sure-flex Sleeve Coupling Flange

Product Description

The TBWOODSTB8S118 TB-8S118 is a Sure-Flex sleeve coupling flange hub designed for use in flexible coupling assemblies on rotating equipment. Rated for coupling size 8, this flange hub accepts a round keyed bore of 1.125 inches and is machined from cast iron for durability under load. It handles a maximum torque of 1,475 inch-pounds and is rated to a maximum speed of 4,500 RPM. The outside diameter measures 5 29/64 inches, with a hub diameter of 3.25 inches and a hub body length of 0.75 inches. Licensed mechanical contractors and millwrights install this component when assembling or replacing Sure-Flex coupling systems on industrial and commercial rotating equipment.

This flange hub is suited for use on compressors, conveyors, motors, and pumps in commercial and light industrial installations. It is a flange hub style, meaning it mates with a Sure-Flex sleeve element rather than a jaw or disc coupling insert. The bore tolerance is +0.0005 inches to +0.0015 inches, allowing for precise shaft fitment. This style of coupling hub is commonly installed where flexible torque transmission and misalignment accommodation are required between a driver and driven shaft.

Installation Notes

Installation of this coupling flange hub should be performed by a qualified mechanic or millwright. De-energize and lock out the motor and associated equipment before disassembly of any coupling components. Ensure the mating shaft is clean, properly sized, and free of burrs before pressing or fitting the hub.
