Tb Wood'S

Tb Wood'S 11HS Sure-Flex Sleeve Coupling Insert Hytrel

SKU CH-0T1K-2X6BB

Hytrel sleeve coupling insert for size 11 Sure-Flex drives, rated 18,000 in-lb torque at 3,600 RPM and 250 °F

  • Handles up to 18,000 in-lb torque for heavy-duty power transmission
  • Hytrel material withstands 250 °F operating temperature in harsh environments
  • Two-piece insert design simplifies installation and maintenance on compressors, conveyors, motors, fans, mixers and pumps
  • Torsional stiffness of 125,000 in-lb/rad ensures precise motion control
  • Rated for 3,600 RPM maximum speed with 0.25° angular and 0.022 in parallel misalignment tolerance

Application Fit

The TB Woods 11HS Sure-Flex sleeve coupling insert is built for inch-system power-transmission drives in compressors, conveyors, electric motors, fans, blowers, mixers and pumps. It suits maintenance teams and OEMs who need a replaceable elastomeric element that handles shock loads and dampens vibration without lubrication. Buyers who require a complete hub-and-sleeve assembly or a different coupling size should look elsewhere.

Speed Torque And Misalignment Limits

The insert is rated for 3 600 RPM maximum speed and transmits up to 18 000 in-lb of torque, delivering 29 hp at 100 RPM. Torsional stiffness is 125 000 in-lb/rad. Angular misalignment capacity is 0.25 degrees and parallel offset is limited to 0.022 in. Operation above 250 degrees F or beyond the stated speed and torque values will exceed the design envelope.

Hytrel Construction And Two Piece Design

The Hytrel insert provides oil resistance and a wide operating temperature range while the new two-piece construction allows installation or replacement without moving connected shafts or hubs. The 4 in insert width and 8 3/16 in outside diameter match the size 11 Sure-Flex hub pattern. The material and split design reduce downtime during scheduled maintenance or unexpected failure.

Questions about this item

How do I choose the right Sure-Flex insert for my coupling size?

This Hytrel sleeve insert is built for coupling size 11 and fits an 8 3/16 inch outside diameter. Verify your hub size matches before ordering.

What does the 18,000 in-lb torque rating mean for my drive?

It is the peak torque the insert can transmit. At 100 RPM the coupling delivers 29 hp, and torsional stiffness of 125,000 in-lb/rad determines how much the shaft twists under load.

What speed limit does the 3,600 RPM rating impose?

Do not exceed 3,600 RPM. The insert also allows only 0.25 degrees angular and 0.022 inch parallel misalignment, and operates up to 250 degrees F.
