TBWOODSTB8H TB-8H Coupling Sleeve Size 8 4500 Rpm

Product Description

The TBWOODSTB8H TB-8H is a Size 8 Sure-Flex Plus coupling sleeve rated for a maximum speed of 4500 RPM. Coupling sleeves serve as the flexible element in jaw-style couplings, absorbing shock and vibration between a driver and driven shaft in power transmission assemblies. This sleeve fits between two coupling hubs and acts as the wear element, isolating torsional shock and damping vibration to protect connected equipment. Installation is handled by millwrights, industrial mechanics, and HVAC technicians working on belt-drive or direct-drive mechanical systems.

The TB-8H coupling sleeve is suited for industrial and commercial power transmission applications where flexible coupling assemblies are used to connect motors to pumps, fans, compressors, and other rotating equipment. The Size 8 designation indicates the coupling family and hub bore range it is designed to fit. At a 4500 RPM maximum speed rating, this sleeve accommodates moderate- to high-speed drive arrangements common in mechanical equipment rooms and industrial installations.

Key Features

• Size 8 Sure-Flex Plus sleeve for jaw-type flexible coupling assemblies
• 4500 RPM maximum operating speed
• Flexible sleeve element absorbs shock and dampens torsional vibration
• Designed as a replaceable wear element to protect hubs and connected machinery

Compatibility

Designed as an OEM-style replacement sleeve for Sure-Flex Plus Size 8 jaw-type flexible coupling assemblies. Specific hub and bore compatibility should be confirmed against the coupling assembly documentation prior to installation.

Installation Notes

Installation is performed by qualified millwrights or mechanical technicians. De-energize and lock out the motor and driven equipment before disassembling the coupling. Inspect hubs for wear or damage before installing the new sleeve. Confirm shaft alignment meets the coupling manufacturer specifications before returning the drive to service.
