Overview
The TB Wood’s 6SC35 is a Sure-Flex Plus Type SC spacer flange engineered for flexible shaft coupling assemblies. This bore-to-size coupling component features cast iron construction for durability and high-speed applications up to 6,000 RPM. The 6SC35 spacer flange bridges two coupling halves, allowing misalignment tolerance while maintaining torque transmission for motors, gearboxes, and driven equipment in industrial automation systems.
Key Features
- Sure-Flex Plus technology for smooth, vibration-damping power transmission
- Type SC spacer flange design (3.5-inch spacer configuration)
- Cast iron hub material for strength and longevity
- Bore-to-size bore type for machine-finished application-specific boring
- Rated 6,000 RPM maximum speed and 585 in-lb maximum torque
- 4-inch outside diameter, 2.5-inch hub diameter, compact footprint
