Tb Wood'S 8S158 Sure-Flex Sleeve Coupling Flange 8S Bore 1-5/8 in

SKU CH-9C6K-5VE6R

Connects shafts in compressors, conveyors, motors and pumps with a 1-5/8 inch bore and 1,475 in-lb torque capacity

  • Ready for compressors, conveyors, motors and pumps
  • Cast iron hub resists wear in tough environments
  • 4,500 RPM rating suits high-speed drives
  • 1,475 in-lb torque capacity handles heavy loads
  • Precise 1-5/8 in bore with tight tolerance

Flange Hub for 8S Coupling Size

This cast iron flange hub fits the 8S Sure-Flex sleeve coupling system. It accepts a 1-5/8 inch round keyed bore with a tolerance of +0.0005 to +0.0015 inches. The hub body length is 3/4 inch and the overall length through bore is 2-3/32 inches. It is designed for compressors, conveyors, motors and pumps.

Cast Iron Construction and Keyed Bore

The hub material is cast iron with a 3-1/4 inch hub diameter and a 5-29/64 inch outside diameter. The round keyed bore provides positive torque transmission without reliance on friction alone. This mounting style suits applications where shaft keys are standard practice and axial retention is required.

Speed and Torque Limits of the 8S Interface

The 8S coupling size carries a maximum speed rating of 4,500 RPM and a maximum torque rating of 1,475 in-lb. These limits define the operational envelope for the complete sleeve coupling assembly. Exceeding either value risks premature wear or mechanical failure of the flexible element.
