TB WOODS

TB Woods is a manufacturer of power transmission components, with a product history dating back to the late 19th century. The company is known for flexible coupling systems, including Sure-Flex sleeve couplings, jaw couplings, and tire couplings, as well as related hubs and inserts. These products are used to connect rotating shafts in industrial machinery, accommodating misalignment, absorbing shock, and dampening vibration. TB Woods couplings are available in both inch and metric configurations, with torque ratings from hundreds to several thousand inch-pounds and speed capabilities up to 7,500 RPM depending on the model. Common applications include pumps, compressors, conveyors, fans, blowers, mixers, and electric motors. The couplings are designed for ease of installation and maintenance; many inserts require no lubrication and can be replaced without moving the connected equipment. 3G Electric supplies TB Woods couplings, hubs, and inserts as part of its global distribution of industrial equipment. The product range includes one-piece and two-piece sleeve coupling inserts, plain bore tire coupling hubs, and straight jaw coupling hubs in various sizes and materials. For plant engineers and maintenance managers, 3G Electric provides access to these components with logistics support and technical documentation to aid in selection and replacement. The TB Woods line is part of a broader offering that includes industrial burners, pumps, gas controls, and related equipment, allowing customers to source multiple system components from a single supplier. 3G Electric serves customers worldwide, with the ability to ship to different regions and support various industrial standards. The company focuses on providing accurate product data and responsive service to help buyers specify the correct parts for their applications. Whether replacing a worn coupling insert or specifying a new drive system, 3G Electric can assist with TB Woods products and other industrial needs.

About TB WOODS

Common Applications

Pumps — TB Woods Sure-Flex sleeve coupling inserts (e.g., 8N, 8H) for connecting pump shafts and absorbing vibration.
Compressors — TB Woods jaw coupling hubs (e.g., L150) with spider elements to accommodate misalignment in compressor drives.
Conveyors — TB Woods tire coupling hubs (e.g., WE5H1) for shock absorption and misalignment in conveyor drive systems.
Fans and blowers — TB Woods Sure-Flex Plus coupling inserts (e.g., 8H) for high-speed fan applications up to 4,500 RPM.
Mixers — TB Woods two-piece sleeve coupling inserts (e.g., 8N) for easy replacement without moving mixer shafts.
Electric motors — TB Woods metric jaw coupling hubs (e.g., L075, L100) for motor-to-driven shaft connections in general purpose drives.

Frequently asked questions

Common questions about TB WOODS from 3G Electric.

What is the difference between TB Woods one-piece and two-piece sleeve coupling inserts?

TB Woods one-piece sleeve coupling inserts are solid, while two-piece inserts include a retaining ring and are split for easier installation or replacement without moving the connected equipment. Both types are used in Sure-Flex couplings to accommodate misalignment and absorb shock. One-piece inserts are often chosen for higher torque capacity, while two-piece designs simplify maintenance. The choice depends on the application requirements and the coupling size.

What are the torque and speed ratings for TB Woods Sure-Flex Plus coupling inserts?

TB Woods Sure-Flex Plus coupling inserts are available with torque ratings from 585 in-lb to 4,530 in-lb, depending on the coupling size and insert type. Maximum speed ratings are typically 4,500 RPM or 6,000 RPM for the sizes shown. For example, the size 8 one-piece insert (8H) is rated for 4,530 in-lb and 7.2 hp at 4,500 RPM, while the size 6 two-piece insert (EPDM) is rated for 585 in-lb at 6,000 RPM. Always verify the specific model's ratings for your application.

Can TB Woods jaw coupling hubs accommodate misalignment?

Yes, TB Woods jaw coupling hubs are designed to work with a flexible spider element that accommodates minor misalignment and dampens vibration. The hubs themselves are rigid, but the complete coupling assembly allows for angular and parallel misalignment within the limits of the spider. This makes them suitable for general purpose power transmission applications where some misalignment may occur. The exact misalignment capacity depends on the coupling size and spider material.

What are the key features of TB Woods tire coupling hubs?

TB Woods tire coupling hubs, such as the WE5 plain bore hub, are designed for use with tire elements that absorb shock and allow for angular misalignment up to 4°. They require no lubrication and use the same hubs for both spacer and standard elements. The WE5 hub is rated for 1.5 hp and a maximum speed of 7,500 RPM. These hubs are commonly used in applications where shock absorption and misalignment compensation are needed, such as in pumps and compressors.

Are TB Woods couplings available in metric and inch sizes?

Yes, TB Woods offers couplings in both inch and metric configurations. For example, the jaw coupling hubs are available with metric bores and outside diameters in millimeters, as well as inch dimensions. The sleeve coupling inserts are available for inch systems, with some models specifically noted as inch-system. When selecting a coupling, ensure the bore size and keyway match your shaft dimensions, and verify the coupling size and torque rating for the application.
