Cast iron flange hub with 1-3/8 inch round keyed bore

Tb Wood'S

Tb Wood'S Sure-Flex Sleeve Coupling Flange 10S Bore 1-3/8 in

SKU CH-MXKY-7XJZ3

A cast-iron flange hub with a 1-3/8 inch keyed bore transmits up to 3,735 in-lb at 3,600 RPM for compressors, conveyors, motors and pumps

  • Coupling size 10 handles 3,600 RPM for high-speed drives
  • 3,735 in-lb torque rating powers compressors, conveyors, motors and pumps
  • 1-3/8 in bore with +0.0005/+0.0015 in tolerance fits shafts precisely
  • Cast iron flange hub resists wear in demanding industrial applications
  • 7-1/2 in outside diameter and 2-23/32 in length suit compact installations

Coupling Flange for Power Transmission

The TB Wood'S Sure-Flex sleeve coupling flange is a cast iron hub designed for mechanical power transmission. It fits compressors, conveyors, motors and pumps requiring a 10S coupling size. The round keyed bore measures 1-3/8 in with a tolerance of +0.0005 in to +0.0015 in. It suits new installations or replacements in industrial machinery.

Thermal and Operational Limits

The flange operates at a maximum speed of 3,600 RPM and transmits a maximum torque of 3,735 in-lb. Cast iron construction handles the heat generated during continuous power transfer. No separate cooling system is required for the hub itself. Performance stays within these limits during normal use across the listed applications.

Build Integration Requirements

The hub diameter is 4 3/8 in with an overall outside diameter of 7 1/2 in. Length through bore is 2 23/32 in and hub body length is 13/16 in. No bushing is needed for this flange hub. Builders must verify shaft diameter matches the bore tolerance and that the coupling size matches the driven equipment. Space for the outside diameter must be available in the mounting area.

Questions about this item

How do I install the 10S flange onto a 1-3/8 in shaft and what step is often missed?

Press the flange onto the shaft within the +0.0005 / +0.0015 in bore tolerance, then secure the key in the round keyed bore; the step often missed is verifying the key seats fully before tightening.

What maintenance or replacement will the 10S coupling flange need over time?

Inspect the cast iron hub for wear or cracking and replace the Sure-Flex sleeve element when it shows fatigue; the flange itself only needs replacement if the 4 3/8 in hub diameter or 2 23/32 in bore length exceeds allowable limits.

At what limit does the 10S flange show stress first during continuous operation?

The 3,600 RPM maximum speed or 3,735 in-lb maximum torque rating will be reached first depending on the application; sustained operation beyond either limit risks hub failure.
