About Tb Woods
TB Wood's coupling catalogue comprises Sure-Flex Plus, Form-Flex, Torsiflex-I Disc, Dura-Flex, L-Jaw, G-Flex grid and rigid couplings. The ATEX-compliant TB Wood's Sure-Flex couplings feature four-way flexing action to minimise shocks and accommodate misalignment. These units have a high torque rating and a flexible design that eliminates the need for lubrication. We also offer TB Woods V belts in different bore diameters for different shaft sizes, designed to transmit power between two parallel axes.
Things to Consider
Cross-Reference Alternatives
TB Wood's product's model numbers generally cross individual reference to the equivalent Lovejoy MPNs (manufacturer's part numbers). So, if you're looking for couplings, flanges, gear & accessories that are either out of stock or obsolete, chances are Raptor Supplies has the alternate product available.
Shipping
These TB Wood's coupling products are generally small in size and require compact packaging. Some models come in a pack of various pieces. They are suitable for courier shipment and not air freight.

Form-Flex couplings transfer torque between two connected shafts while accommodating angular, parallel & axial misalignment. These couplings have all-metal construction with no moving parts for high t...Read more
Dura-Flex Couplings
Dura-Flex couplings use finite element analysis to maximise flex life and a lightweight element to absorb loading shock & torsional vibrations. These easily replaceable couplings have a versatile spac...Read more
G-Flex Couplings
These taper grid couplings are made from hardened & tempered high tensile alloy steel that is shot-peened. This causes the grid spring to form a stressed surface layer under compression and prevents c...Read more
Frequently Asked Questions
What standards / certifications do TB Wood's couplings abide by?
TB Wood's company is ISO 9001 certified, maintaining superior quality while manufacturing couplings. The brand's Sure-Flex Plus couplings and Dura-Flex couplings are ATEX certified for user safety in explosive environments.
What are the uses of TB Wood's couplings?
TB Wood's couplings transmit torque and rotational force from one shaft to another while handling shaft misalignment. These couplings can also dampen shocks & vibrations to prevent component damage.
Where are gear couplings used?
Gear couplings are generally used in large machines like pumps, blowers, compressors & mixers. They are suitable to reduce backlash in smaller equipment.
