TB Woods 5J-1 1/8 Flange

The TB Woods 5J-1 1/8 is a Size 5 Sintered Carbon Steel Type J Sure-Flex Plus Coupler Flange engineered for reliable power transmission in demanding HVACR and industrial pump applications. Designed with a 1 1/8" Bore and a precision 1/4" x 1/8" Keyseat, this flange ensures a secure, interference-fit match on standard motor shafts to eliminate slippage. The sintered steel construction provides high density and strength, making it an ideal choice for direct-drive coupling replacements where torsional vibration and shock loads are present. This Sure-Flex Plus coupling component is optimized for 4-way flexing action, accommodating angular, parallel, and axial misalignment while reducing wear on connected equipment bearings. Whether you are performing a motor to pump shaft alignment or upgrading a blower assembly, the TB Woods 5J series delivers the necessary durability for high-torque environments without the need for lubrication or frequent maintenance intervals.

• Sintered Carbon Steel Construction: Offers superior structural integrity and corrosion resistance for long-term mechanical power transmission.
• Precision Machined 1 1/8" Bore: Ensures exact fitment on NEMA frame motor shafts, reducing runout and vibration.
• Interchangeable Design: Fully compatible with EPDM, Neoprene, and Hytrel sleeves, allowing for flexible system configuration based on environmental requirements.
• High Torque Capacity: Rated to handle significant startup loads and fluctuating torque demands typical in commercial air handling units.

What is the maximum RPM for the TB Woods 5J-1 1/8 flange?
The Type J sintered steel flange is typically rated for speeds up to 7,600 RPM, though the specific sleeve insert material will ultimately dictate the operating limits of the complete assembly.

Does this flange require a specific sleeve type?
The 5J flange is designed to work with all Size 5 Sure-Flex sleeves (JE, JNS, E, N, H, and HS). The choice of sleeve depends on your specific torque requirements and ambient operating temperatures.

Is the keyway included in the bore dimensions?
Yes, this unit features a factory-broached 1/4" x 1/8" keyseat specifically sized for a 1 1/8" shaft to ensure standard ANSI compliance.
