TB Wood's

What TB Wood's does

TB Wood's Incorporated, founded in 1857 in Chambersburg, Pennsylvania, designs and manufactures industrial couplings and belted drive solutions, with operations comprising four product categories: couplings (Sure-Flex Plus, Dura-Flex, Form-Flex, G-Flex, L-Jaw, Torsiflex-I), belted drives (V-belt sheaves, QT Power Chain synchronous systems, bushings, variable speed drives), commercial castings (gray and ductile iron up to 10,000 lbs per part), and clutches & brakes (Disc-O-Torque hydraulic, Roto-Cam mechanical). The company operates an ISO 9001 certified foundry with integrated machining, solidification modeling, and metallurgical testing capabilities supporting custom made-to-order sheaves up to 107-inch diameter, and runs a second manufacturing facility in San Marcos, TX for Form-Flex and Torsiflex disc couplings. TB Wood's is a wholly-owned subsidiary of Regal Rexnord Corporation (NASDAQ: REX, formerly Altra Holdings) since April 2007.

The company serves industrial OEMs and end-users across Oil & Gas, Mining & Aggregate, Industrial Manufacturing, Food & Beverage, Wastewater Treatment, Material Handling, Agriculture, and Outdoor Power Equipment verticals, supplying power transmission components for applications ranging from conveyor systems and pumps to drilling rigs and combines. Go-to-market operates through a global network of industrial distributors covering 40+ countries across North America, Europe, Asia Pacific, Middle East, Latin America, and Africa, supplemented by direct factory-based customer service, regional toll-free support lines, dedicated online ordering portals for USA and Canada, and interactive selection tools (couplingselector.com, beltdriveselector.tbwoods.com). Pricing is not publicly disclosed; the model is B2B hardware sales with custom quote-based pricing on made-to-order products and OEM arrangements, supported by technical engineering application support.

Revenue mechanics are anchored by hardware sales across the four product lines plus complete-to-print commercial casting services; the company emphasizes response time, in-stock SKU availability, and integrated foundry-to-finished-part vertical scope as primary commercial differentiators. Brand strength is supported by registered trademarks across the proprietary product family, participation in trade conferences (OTC 2023, TPS 2023), and a recognized position as the No.1 producer in each of its mechanical product categories. TB Wood's name is treated as virtually synonymous with power transmission products, leveraging over 165 years of operational heritage.

Core offering

TB Wood's designs and manufactures industrial power transmission components, including elastomeric, disc, grid, and jaw couplings; V-belt sheaves, synchronous belt drives, bushings, and variable speed drives; commercial gray and ductile iron castings; and hydraulic and mechanical clutches and brakes. Products are sold primarily through industrial distributors and direct factory channels to equipment manufacturers and end users in oil and gas, mining, food and beverage, wastewater, agriculture, material handling, and other heavy industries.

Product overview

TB Wood's is a manufacturer of industrial power transmission components organized around four core product categories: Couplings, Belted Drives, Commercial Castings, and Clutches & Brakes. The couplings portfolio includes elastomeric couplings (Sure-Flex Plus, Dura-Flex, L-Jaw), disc couplings (Form-Flex, Torsiflex-I), and grid couplings (G-Flex). The belted drives portfolio encompasses V-belt sheaves, synchronous drives (QT Power Chain systems), bushings (Sure-Grip, Taper-Lock), and variable speed drives. Commercial Castings represent foundry operations producing gray and ductile iron parts up to 10,000 lbs. Clutch and brake products include Disc-O-Torque hydraulic and Roto-Cam mechanical clutches. TB Wood's also offers internal web-based selection tools (Online Belted Drive Selection Application, Online Coupling Selection Program) and selector programs for product specification.

Direct peers

• Lovejoy (Curtiss-Wright): Lovejoy, now part of Curtiss-Wright, is a direct competitor in elastomeric, disc, and jaw couplings for industrial power transmission. Its product portfolio (including the popular Spider jaw coupling inserts) directly overlaps with TB Wood's Sure-Flex, Form-Flex, and L-Jaw coupling lines, serving the same industrial OEM and MRO customer base.
• Martin Sprocket & Gear: Martin Sprocket & Gear manufactures power transmission components including couplings, sheaves, sprockets, and conveyor products. It directly competes with TB Wood's coupling and belted drive lines, serving the same industrial distributor network and end markets including material handling, mining, and aggregate.
• Gates Industrial: Gates Industrial is a global leader in power transmission and fluid power belts and hoses, directly competing with TB Wood's V-belt sheaves, synchronous drives (QT Power Chain), and timing belt products. Gates' industrial belt portfolio and global distribution overlap closely with TB Wood's belted drive business.
• KTR Systems: KTR Systems is a German-based manufacturer specializing in mechanical power transmission components including elastomeric, jaw, gear, and disc couplings. Its Rotex and BoWex coupling lines directly compete with TB Wood's Sure-Flex and L-Jaw products in European and global industrial markets.

Broad incumbents

• Dodge (Regal Rexnord): Dodge is a sister brand under Regal Rexnord offering mounted bearings, gear reducers, and power transmission components. While it competes in adjacent product categories (bearings, gearboxes) rather than TB Wood's core couplings and sheaves, both brands share distribution channels and serve overlapping industrial customers within the Regal Rexnord portfolio.
• Boston Gear (Regal Rexnord): Boston Gear is another Regal Rexnord sister brand offering enclosed gear drives, gear reducers, and related power transmission products. While it focuses more on enclosed gearing than TB Wood's open belt drives and couplings, both brands address industrial power transmission requirements through the same parent distribution channels.
• ContiTech (Continental): ContiTech, Continental's industrial rubber and polymer business, manufactures industrial belts including V-belts, timing belts, and conveyor belts. It competes with TB Wood's belted drive products (V-belts, QT Power Chain synchronous systems) globally with deeper European market penetration.
• Rexnord (Regal Rexnord): Rexnord's process and motion control business, now part of Regal Rexnord, manufactures industrial chains, bearings, gears, and couplings. While Rexnord's chain products are not direct competitors to TB Wood's belts, its coupling and gear products overlap with TB Wood's industrial coupling portfolio across shared distribution channels.
• Tsubaki Power Transmission: Tsubaki manufactures power transmission products including roller chains, timing belts, and coupling products. While its chain products do not directly compete with TB Wood's couplings, its timing belt portfolio (Poly Chain) competes with TB Wood's QT Power Chain synchronous belt drives in industrial applications.
• SKF: SKF is a global bearings and power transmission manufacturer offering couplings (including SKF Flex and OK couplings) that compete directly with TB Wood's elastomeric coupling lines. While SKF is far larger and more diversified, its coupling products address the same industrial customer base with similar mechanical performance characteristics.
