For over 50 years, TB Wood’s has led the coupling industry with the original TB Wood’s Sure-Flex design. And we haven’t stopped innovating: this industry favorite just got even better.

​

Our new Sure-Flex® Plus EPDM and Neoprene sleeves are best-in-class for coupling performance and value. 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.

Sure-Flex's Product Features

  • High Torque Rating - 30% Increased Torque Rating

  • Longer Life - Sure-Flex Plus Lasts Over 3X Longer than the Competition

  • Better Value - Save Money Using a Smaller Coupling

  • Interchangeable - Retrofits to Existing Flanges

  • Up to 8.20 kNm; 72,480 in.lb.

  • 7 to 15 degree torsional wind-up.

  • Easy assembly Spacer, bushed hub, and clamping hub designs in stock

  • Flexible design accommodates misalignment and protects equipment

  • No lubrication required.

  • One piece, split and two piece sleeve construction allows for easy installation under any conditions.

  • SureFlex® is ATEX Compliant

2. Dura-Flex

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 (QD) hubs.

Dura-Flex's Product Features

  • Up to 4.50 kNm; 39,500 in.lb.

  • Easy to assemble/replace

  • High misalignment ratings

  • No maintenance/lubrication

  • Part-for-part interchangeable with industry standard design

  • In-stock versatile spacer design can accommodate many configurations with few parts

  • Designed from the ground up using finite element analysis to maximize flex life.

  • Easy two piece element installation. No need to move the hubs during replacement.

  • One spacer size to handle most different between shaft spacings.

  • Light weight element absorbs shock loading and torsional vibration.

  • Same hubs used on both spacer and standard elements.

  • Good chemical resistance.
