TB Woods 5J-5/8 Flange

The TB Woods 5J-5/8 Flange is a critical power transmission component designed for high-demand industrial and HVACR systems. Engineering with sintered carbon steel for maximum structural integrity, this Type J Sure-Flex Plus coupler flange provides a refined 5/8" finished bore featuring a precision-machined 3/16" x 3/32" keyseat. As a primary component in a sleeve coupling system, it is purpose-built to facilitate 4-way flexing action, which effectively manages angular and parallel misalignment while dampening torsional shock. Contractors often specify the Sure-Flex Plus 5J for its high torque rating and maintenance-free operation, as the interlocking tooth design requires no lubrication. This specific 5J58 model ensures a reliable interference fit on the drive shaft, reducing vibration in pump and motor assemblies and extending the service life of connected bearings. Its robust metal-to-elastomer interface is optimized for consistent performance under varying load conditions, ensuring mechanical power transmission stability in the field.

• Enhanced torsional wind-up capacity (7° to 21°) to absorb startup shock and protect sensitive drivetrain components.
• Manufactured from high-strength sintered carbon steel for superior durability compared to standard cast iron alternatives.
• Compatible with EPDM, Neoprene, and Hytrel sleeves, allowing for tailored performance based on environmental exposure.
• Features a standard 5J size footprint for seamless integration into existing TB Woods Sure-Flex Plus coupling setups.
• No-lubrication design drastically reduces routine maintenance requirements in industrial HVAC blower and centrifugal pump applications.

• How do I ensure proper shaft alignment with the 5J-5/8 flange? Use a straightedge and calipers across the precision-machined outside diameters of the flanges to verify parallel and angular status before tightening the set screws.
• Can this flange be used with a 5JE or 5JN sleeve? Yes, the 5J size flange is fully compatible with all Size 5 Sure-Flex Plus EPDM (5E/5JE) and Neoprene (5N/5JN) one-piece or two-piece sleeves.
• Is the keyway included in the 5/8" bore? Yes, this flange comes pre-machined with a standard 3/16" x 3/32" keyseat to secure the connection against high-torque rotational forces.
