TB Woods 8H Insert

Maintain peak drivetrain efficiency with the TB Woods 8H Insert, a one-piece solid Hytrel sleeve engineered for high-torque power transmission. Specifically designed for Sure-Flex Plus size 8 couplers, this Hytrel coupling insert provides four times the torque capacity of standard EPDM or Neoprene alternatives, making it the industry standard for demanding HVACR applications like large compressors, blowers, and pumps. This industrial elastomer sleeve utilizes a 7-degree torsional wind-up to effectively dampen vibration and handle mechanical shaft misalignment, protecting your motor and driven equipment from premature wear. Built for durability in harsh environments, it operates reliably across a wide temperature range of -65°F to +250°F and is resistant to most oils and chemicals found in mechanical rooms. This direct replacement sleeve eliminates the need for lubrication, significantly reducing maintenance intervals on critical plant equipment.

Key Benefits:

• High Torque Density: Transmits up to 4,530 in-lbs of torque, ideal for high-load startup conditions.
• Precision Misalignment Handling: Accommodates up to 0.25 degrees of angular misalignment and 0.015 inches of parallel misalignment.
• Maintenance-Free Operation: Solid elastomeric coupling design requires no grease or oil, ensuring a clean and quiet environment.
• Broad Operating Window: Rated for speeds up to 4,500 RPM with superior thermal stability in extreme cold or heat.

Common Questions:

• Can I use an 8H Hytrel insert with Type J or B flanges? No, Hytrel sleeve inserts must only be used with S, C, or SC flanges. They are not compatible with J or B flanges due to the material's specific stiffness and torque requirements.
• What is the difference between 8H and 8HS inserts? The 8H is a one-piece solid construction, while the 8HS is a split version. The solid 8H provides maximum integrity for high-speed rotors but requires sliding a flange back during installation.
• Can this Hytrel insert replace an EPDM sleeve directly? While it fits the same size 8 Sure-Flex Plus coupling, Hytrel is much stiffer. You should confirm your system's torsional requirements before upgrading from EPDM to Hytrel to ensure the drive remains properly tuned.
