TB Woods

TB Woods is a leading American manufacturer of power transmission systems and industrial drive components with over 125 years of experience. The company is renowned for its reliable V-belts, flexible couplings, variable speed drives, gearboxes, and sheaves for heavy industrial applications. TB Woods products are found in factories worldwide wherever reliability and precision are essential.

The TB Woods product range includes V-belts in classical, narrow, and poly-V configurations, cogged belts for increased flexibility, synchronous timing belts for precision drives, and banded multi-belt sets for heavy-duty applications. Sheaves are available in cast iron, steel, and aluminum in all standard profiles (A, B, C, D, 3V, 5V, 8V).

The TB Woods coupling line is particularly comprehensive: the SURE-FLEX nylon coupling, the FALK WRAPFLEX rubber coupling, and the SFC rigid coupling are industry standards for connecting motors to pumps, compressors, and gearboxes. The GRID-FLEX metal grid coupling is specifically engineered for high-torque applications with shock loading conditions.

TB Woods also supplies variable pitch drives that allow continuous adjustment of the drive ratio without stopping, ideal for fans, pumps, and conveyors requiring variable process speeds. This significantly improves energy efficiency compared to fixed-ratio drives.

At Verkopershulp.nl we carry over 11,779 genuine TB Woods parts from stock. As an authorized distributor we supply all products with full warranty, technical datasheets, and support in selecting the correct V-belt size, sheave, or coupling for your drive application.

History

TB Woods was founded in 1857 in Chambersburg, Pennsylvania (USA) as a foundry. In the early 20th century the company transitioned to power transmission systems and became a pioneer in V-belt technology for American industry. In the 1950s and 1960s TB Woods grew into a national supplier of drive components for the process industry, mining, and energy sectors. The 1980s and 1990s saw acquisitions of related brands and international distribution expansion. TB Woods became part of Rexnord Corporation, after which the brand retained its independent product identity while benefiting from a larger distribution network. The company introduced new materials for belts and couplings resistant to higher temperatures, chemicals, and extreme loads. Today TB Woods continues to innovate with improved elastomer formulations, higher power density in compact belt profiles, and comprehensive configuration tools for drive calculations. The brand is distributed worldwide through authorized partners including Verkopershulp.nl.

Frequently Asked Questions

How do I select the correct TB Woods V-belt?
V-belt selection depends on the power to be transmitted, the drive and driven sheave diameters, the center distance, and the shaft speed. Use TB Woods drive calculation tools or our technical specialists at Verkopershulp.nl to determine the correct profile (A, B, C, 3V, 5V, or 8V) and length. Also consider ambient temperature and any oil or chemical exposure when choosing belt material.
What is the difference between a classical V-belt and a narrow V-belt?
Narrow V-belts (3V, 5V, 8V) have a smaller width-to-height ratio than classical belts (A, B, C, D), giving them a higher power density per unit width. Narrow belts suit smaller sheave diameters and can transmit more power in a more compact space. They are ideal for high-speed and high-power applications.
Which TB Woods coupling is suitable for connecting an electric motor to a pump?
The TB Woods SURE-FLEX flexible coupling is the most commonly used choice for motor-pump connections. It compensates for minor shaft misalignment (radial, axial, and angular) and dampens shock and vibration forces. For higher torque loads or shock conditions, the GRID-FLEX metal grid coupling is a better choice due to its higher torque capacity.
How long do TB Woods V-belts last?
Belt life depends strongly on correct installation, alignment, tension, and environmental conditions. Correctly installed and tensioned TB Woods V-belts have a typical service life of 20,000-40,000 operating hours. Poor alignment, over- or under-tensioning, and high temperatures significantly shorten service life. Regular inspection and timely replacement prevent unplanned downtime.
Are TB Woods sheaves compatible with belts from other manufacturers?
TB Woods sheaves are manufactured to ISO, RMA, and MPTA standard profiles, making them compatible in most cases with V-belts from other manufacturers following the same profile standard. For optimum performance and service life we recommend combining belt and sheave from the same manufacturer.
How do I set correct tension on a TB Woods V-belt?
A correctly tensioned V-belt deflects approximately 1/64 inch per inch of center distance under light finger pressure (approximately 2-5 kg). Too little tension causes slippage and heat; too much tension overloads bearings and shortens belt and sheave life. TB Woods provides specific tension guidelines per belt series in their installation manual.
Does Verkopershulp.nl supply matched belt sets for multiple V-belt drives?
Yes, for multiple V-belt drives it is essential to use matched belt sets where all belts have the same effective length. TB Woods supplies such matched sets to prevent one belt from carrying the full load. We supply these sets from stock or to order.
How do I correctly install a TB Woods SURE-FLEX coupling?
Install the coupling half on both shafts with the correct fit and set screw. Align the shafts as accurately as possible (recommended max. 0.5 mm radial and 0.5° angular deviation). Ensure the rubber flexible insert ring is fully seated before assembly. Check alignment after warm-up at first commissioning.
