Couplings TB Wood’s offers a solution for any coupling application with several lines of high-performance couplings. Wood’s lines of elastomeric, disc and gear couplings have a reputation of reliability and flexibility. Whether you choose from our Sure-Flex®, Dura-Flex®, Form-Flex®, Jaw, or Grid Couplings, you can be certain you’re getting the very best of Wood’s performance and quality.

Sure-Flex® couplings

TB Wood's Sure-Flex® couplings use a rubber (EPDM), neoprene, or Hytrel sleeve and have exceptional torsional flexibility. Their 4-way flexing action absorbs virtually all types of shock, misalignment, and end float.

With Sure-Flex couplings, the need for lubrication and maintenance is eliminated. As a result, these couplings provide clean, dependable, and quiet performance for a variety of applications.

Product features

Lubrication-free design provides quiet, reliable performance Flexible sleeves available in EPDM, Neoprene, and Hytrel Fast and easy installation without bolts, gaskets, covers or seals Uniquely designed teeth and lateral flexibility accept both parallel and angular misalignment without wear Choose from an extensive offering of sizes, using BTS, bushed, clamp and spacer flanges Four-way flexing action absorbs extreme torsional shock and vibration.


Dura-Flex® couplings

TB Wood’s Dura-Flex® couplings are designed from the ground up using finite element analysis to maximize flex life. Perfect for a wide variety of applications -- including those with uniform to heavy shock loads -- Dura-Flex® couplings employ a light weight element that absorbs shock loading and torsional vibration. These couplings are available in stock bore-to-size (BTS, Taper-Lock® and Sure-Grip® bushed (QT) hubs.

Product specifications

  • Bore-to-size (BTS), Sure-Grip bushed (QD), and Taper-Lock® hubs are available
  • Specially designed "split-in-half flex element" moves stress away from bond, extending flex life
  • Directly interchangeable with similar couplings for fast and easy replacement
  • One spacer size eliminates problems with varying between-shaft spacings
  • Requires no lubrication, minimizing maintenance and downtime
  • Flexible polyurethane material offers superior chemical, dynamic, and weathering properties

jaw Couplings

Jaw couplings

TB Wood’s Jaw couplings are designed to meet high-quality standards while remaining affordable. Wood’s offers two Jaw-type elastomeric couplings: a straight L-Jaw coupling available with four insert materials and a straight C-Jaw coupling designed for high-torque loads. Both are 100% interchangeable with industry-standard designs.

Product features

  • Spiders available in Burna-N, Urethane, Hytrel and bronze
  • L-Jaw and C-Jaw versions offer reliable solutions for uniform to heavy loads
  • L-Jaw straight-jaw coupling is directly interchangeable with industry standard couplings
  • C-Jaw uses easily replaceable individual cushions for maximum reliability with heavy torque loads

Form-Flex® Couplings - Flexible Disc Couplings

Form-Flex® couplings transmit torque while compensating for angular, parallel and axial misalignment between two connected shafts. Flexible disc couplings minimize the misalignment forces on the connected equipment.

Product features

  • High-strength, flexible, stainless-steel discs are available in three styles: 4-bolt, straight-sided (A, M series); 6-bolt, straight-sided (B Series); and 8-bolt, round (D, F, H series). Alloy discs are also available
  • Transmits torque with zero backlash while compensating for angular and parallel misalignment between two connected shafts
  • Ideal for smooth or uneven conditions and moderate to heavy loads where elastomeric couplings are a typical problem
  • Close-coupled, spacer and floating shaft designs offer total solutions for pumps, engine-driven equipment, printing, and positioning systems.
  • Reduces maintenance time and costs by eliminating lubrication

Rigid Couplings

Rigid Couplings

TB Wood’s Rigid couplings are ribbed-type compression couplings that are recommended for emergency and regular service on heavily loaded shafts. These couplings are bored true to shaft size, and the halves are separated during the boring operation to allow for clamping when the halves are drawn together.

Product features

  • Bolt heads and nuts protected by flanges
  • Bored true to shaft size
  • Recommended for emergency and regular service on heavily loaded shafts
  • Outer diameters turned
  • End flanges faced square to bore
  • Flexible polyurethane material offers superior chemical, dynamic, and weathering properties

G - Flex Grid Couplings

G - Flex Grid Couplings

TB Wood's Grid coupling continues the tradition of the original Bibby Resilient Coupling, invented by Dr. James Bibby. The coupling is designed for long life under tough application conditions.

Taper Grid replacement and maintenance can be performed quickly and easily without the need to move and realign connected equipment.

Sizes 1020 through 1140 in-stock and interchangeable with industry standard designs.

Product features

  • Positive protection against damaging effects of shock loads and vibration
  • Proven interchangeable industry design, allowing for easy replacement of component parts
  • Horizontal T10 and Vertical T20 design options in stock and available
  • In stock inventory of sizes 1020 through 1140, accommodating up to 7.25" diameter shafts
