TB Woods 8HS Insert

Optimize your power transmission setup with the TB Woods 8HS Insert, a high-performance Hytrel split sleeve coupling engineered specifically for Sure-Flex Plus size 8 assemblies. Designed for high-torque applications where EPDM or Neoprene fail to meet demand, this split sleeve insert offers a significant 4,530 in-lb torque rating. The two-piece HS-type construction featuring a heavy-duty retaining ring allows for rapid installation and maintenance without necessitating the decoupling of hubs, drastically reducing system downtime in critical HVACR and industrial environments.

Built for resilience, the Hytrel material provides superior chemical resistance and operates reliably within a temperature range of -65°F to +250°F. This elastomeric coupling insert manages a maximum speed of 4,500 RPM and effectively dampens torsional vibration while accommodating up to 7° of torsional wind-up. By utilizing this split design coupling, contractors can achieve 4-way flexing action that absorbs angular, parallel, and axial misalignment, protecting the motor and driven equipment bearings from premature wear.

• High Torque Capacity: Delivers four times the power transmission capability of standard EPDM inserts, rated for 4,530 in-lbs of torque.
• Superior Material Durability: Hytrel construction resists oil, grease, and many common industrial solvents for long-term stability.
• Easy Installation: The two-piece split design allows for retrofitting and replacement without moving the flanges or connected shafts.
• High-Speed Stability: Precision-molded to maintain balance and performance at speeds up to 4,500 RPM.
• Advanced Misalignment Absorption: Protects driveline components by handling 0.015-inch parallel and 0.025-inch angular gap misalignment.

Common Questions:

Can I use an 8HS Hytrel insert with Type J or B hubs?
No. Hytrel sleeves are specifically designed for use with Type S, C, or SC flanges. They are not compatible with Type J or B hubs due to the specialized tooth engagement required for high-torque transmission.

What is the primary advantage of the split HS design over the solid H sleeve?
The split 8HS design, which includes a stainless steel retaining ring, allows for the replacement of the insert without disassembling the shaft or moving the flanges. This is ideal for equipment with limited access where pulling the motor would be labor-intensive.

How does Hytrel affect the torsional stiffness of my coupling?
Hytrel is significantly stiffer than EPDM or Neoprene. It provides approximately 7° of torsional wind-up at rated torque, compared to 21° for rubber inserts, making it the preferred choice for applications requiring precise timing or minimal backlash.
