TB Woods 10S-2 1/8 Flange

The TB Woods 10S-2 1/8 Flange is a high-performance Sure-Flex Plus Type S coupler flange engineered for heavy-duty industrial power transmission. Constructed from high-strength cast iron, this Size 10 flange features a precise 2 1/8" bore with a standard 1/2" x 1/4" keyseat to ensure a secure, slip-free attachment to the drive shaft. Transitioning to the Sure-Flex Plus design provides a 30% increase in torque capacity compared to older models, reaching a torque rating of 11,350 in-lbs. This sleeve coupling flange is designed for a maximum speed of 3,600 RPM, making it a reliable choice for HVACR motor-to-pump and fan applications.

For technicians navigating shaft misalignment, this cast iron coupling utilizes a 4-way flexing action to absorb shock, vibration, and end float. It is 100% interchangeable with industry-standard 10S flanges, including those from Lovejoy, providing a true drop-in replacement for Type S flexible couplings. With a 7.50-inch outside diameter and a 2 23/32-inch length through bore, this component is optimized for performance in pumps, compressors, and blowers. The 10S-2 1/8 ensures smooth power delivery without the need for lubrication, reducing maintenance requirements in demanding mechanical environments.
