TBWOODSTB7J TB-7J Sure-flex Plus Coupling Sleeve Size 7

Product Description

The TBWOODSTB7J TB-7J is a 1-piece solid Type JE elastomeric coupling sleeve designed for use with Sure-Flex Plus flange and elastomeric couplings. Manufactured from EPDM rubber with a black finish, this sleeve provides flexible torque transmission between coupled shafts in mechanical power transmission applications. It is rated for up to 940 inch-pounds of torque and a maximum speed of 5,250 rpm, with an operating temperature range of -30 to 275 degrees F. The sleeve measures 2-3/16 inches in length with an outside diameter of 4-11/32 inches and accepts shaft bore sizes from 5/8 to 1-7/8 inches. Installation is handled by qualified mechanical or industrial service technicians.

This coupling sleeve is suited for industrial and commercial mechanical drive systems where shock absorption, misalignment accommodation, and end float compensation are required. The 4-way flexing action of the EPDM elastomer allows the sleeve to handle angular, parallel, and axial misalignment simultaneously. The design eliminates the need for lubrication or routine maintenance once installed, making it well suited for pump drives, compressor connections, fan shafts, and similar rotating equipment found in HVAC, industrial process, and commercial mechanical systems.

Key Features

• 1-piece solid Type JE construction for straightforward sleeve replacement without disturbing flanges
• EPDM elastomer material rated from -30 to 275 degrees F for broad service temperature range
• Accepts inside diameters from 5/8 to 1-7/8 inches to fit a range of shaft sizes
• Rated to 940 inch-pounds torque and 5,250 rpm maximum speed
• Lubrication-free design reduces maintenance requirements
• 4-way flexing action absorbs shock, angular misalignment, parallel offset, and end float

Compatibility

Designed for use with Sure-Flex Plus flange and elastomeric couplings, Coupling Size 7.

Installation Notes

Installation is typically performed by a qualified mechanical technician or millwright. De-energize and lock out all drive equipment before removing the existing sleeve or handling coupling components. Ensure mating flanges are clean and free of debris before seating the new sleeve. Verify shaft alignment is within the coupling manufacturer's specified tolerances after reassembly to prevent premature sleeve wear.
