Tb Wood'S

Tb Wood'S 7N Sure-Flex Sleeve Coupling Insert Neoprene

SKU CH-1GK1-BYGJB

Neoprene sleeve coupling insert for size 7 couplings, rated to 5,250 RPM and 940 in-lb torque with 1.5 hp at 100 RPM

  • Handles 940 in-lb torque for heavy-duty power transmission
  • Runs up to 5,250 RPM in high-speed machinery
  • Neoprene insert resists heat up to 200 degrees F
  • Two-piece design with retaining ring simplifies installation
  • Delivers 1.5 hp at 100 RPM for efficient operation

Coupling Insert Size 7

The Tb Wood'S 7N Sure-Flex sleeve coupling insert is a neoprene flexible element rated for 5,250 RPM and 940 in-lb maximum torque. It fits machinery drives such as blowers, compressors, conveyors, mixers, motors and pumps where vibration damping and misalignment tolerance are required.

Two-Piece Retaining Ring Design

The new two-piece construction with a retaining ring simplifies installation and removal without moving the connected shafts. Neoprene material provides oil resistance and operates up to 200 degrees F, while the insert accommodates 1 degree angular and 0.02 in parallel misalignment to protect bearings.

Inch-System Mechanical Limits

Torsional stiffness is rated at 2,769 in-lb per radian and the insert delivers 1.5 hp at 100 RPM. The outside diameter measures 4 11/32 in with a 2 3/16 in width, so the coupling suits only applications that match these exact inch dimensions and torque envelope.

Questions about this item

How often should the neoprene insert be inspected or replaced on the Tb Wood'S 7N Sure-Flex coupling?

The neoprene insert is a wear item; inspect it during scheduled downtime for cracks, hardening, or loss of torsional stiffness and replace it when misalignment capacity drops below the rated 1 degree angular or 0.02 in parallel limits.

What is the first limit reached when running the Tb Wood'S 7N coupling continuously at high load?

The 200 degrees F maximum operating temperature is the primary sustained-use limit; exceeding it degrades the neoprene and reduces the 940 in-lb torque rating.

How much heat does the Tb Wood'S 7N insert generate during all-day operation at rated speed?

At 5,250 RPM and 1.5 hp per 100 RPM the insert dissipates power through hysteretic damping; its 2,769 in-lb/rad torsional stiffness limits temperature rise, but continuous duty near the 200 degrees F ceiling requires verification.
