TB Woods 5J-7/8 Flange

The TB Woods 5J-7/8 Sure-Flex Plus Flange is a critical component for high-performance power transmission in HVACR and pumping systems. Manufactured from sintered carbon steel using an advanced powdered metal process, this Size 5 Type J flange offers superior dimensional accuracy and uniform material density compared to standard cast iron alternatives. Engineering for a 7/8" finished bore with a standard 3/16" x 3/32" keyseat, it provides a precise slip fit on standard motor and drive shafts. This bored-to-size (BTS) coupling flange is designed to integrate seamlessly with Sure-Flex Plus EPDM and Neoprene sleeves, leveraging a 4-way flexing action that effectively absorbs shock, vibration, and end float. The precision-machined outside face allows technicians to perform alignment using only a straightedge and calipers, streamlining installation in tight mechanical rooms. With a maximum rating of 7,600 RPM, this industrial shaft coupling flange ensures reliable torque transfer even in demanding high-speed blower and compressor applications.

• Precision Tolerance: Powdered metal construction ensures high strength and a consistent bore tolerance of +.0005" to +.0015" for a secure shaft interface.
• Maintenance-Free Design: When paired with a Sure-Flex Plus sleeve, the assembly requires no lubrication or periodic adjustment.
• Vibration Dampening: The torsional flexibility of the elastomeric coupling system protects motor bearings and driven equipment from premature wear.
• Dynamic Balancing: Sintered steel provides inherent balance at high speeds, supporting operation up to 7,600 RPM.

What sleeve materials are compatible with the 5J-7/8 flange?
This Type J flange is specifically designed for use with EPDM (J, JE, JES) and Neoprene (JN, JNS) sleeves. It is not intended for use with Hytrel or Urethane inserts.

Does this flange require special tools for alignment?
No. The flange faces are precision-machined so you can check parallel and angular alignment using standard technician tools like a straightedge and feeler gauges.

Is the keyway and setscrew included?
Yes, the TB Woods 5J-7/8 features a standard 3/16" x 3/32" keyseat with one setscrew positioned over the keyway and a second setscrew at 90 degrees for maximum holding power.
