TB Woods 3J-5/8 Flange

The TB Woods 3J-5/8 Sure-Flex Plus Flange is a high-performance sintered carbon steel coupling component engineered for precision in fractional and small-horsepower motor applications. Manufactured through a specialized powder metallurgy process, this Type J BTS coupler flange offers exceptional dimensional stability and uniform material density, providing the high-strength performance required in light-duty HVAC and pumping systems. Featuring a 5/8" finished bore with a standard 3/16" x 3/32" keyseat and integrated setscrew, it ensures a secure, slip-fit installation on standard power transmission shafts. Designed for close-coupled configurations, this Size 3 flexible coupling flange is rated for speeds up to 9200 RPM and is fully compatible with EPDM and Neoprene sleeves. The machined outside diameter allows technicians to verify parallel and angular alignment using basic tools like straightedges and calipers, streamlining field maintenance without the need for specialized equipment.

Key Benefits:

• High-Strength Construction: Sintered carbon steel provides a durable, precision-engineered hub that outperforms standard cast-iron alternatives in Size 3 configurations.
• Simplified Alignment: The precision-machined flexible coupling hub face allows for rapid alignment checks, minimizing vibration and extending the service life of connected drive components.
• Compact Form Factor: The 3J design is optimized for space-constrained installations while maintaining a torque rating of 60 in-lbs when paired with a compatible sleeve.
• Reliable Shaft Attachment: Equipped with a standard 3/16" keyway and setscrew to prevent slippage and maintain timing in dynamic load applications.

Common Questions:

• Can I use a Hytrel sleeve with a Size 3J flange? No, Type J flanges are specifically designed for EPDM and Neoprene sleeves; Hytrel sleeves are not compatible with this flange geometry.
• What is the maximum operating speed for this coupling? This Size 3 sintered steel flange is rated for a maximum speed of 9200 RPM.
• Does this flange require lubrication during maintenance? No, the Sure-Flex Plus system is a non-lubricated design, reducing maintenance overhead and preventing contamination in sensitive HVACR environments.
