Jaw and Flexible Shaft Couplings 

MD Flex Couplings 

Solve’s MasterDrive brand flexible couplings are ideal for accommodating shaft misalignment, reducing vibrations, and transmitting torque smoothly. They enhance machinery performance, prevent damage, and extend the lifespan of connected components. 


  • No lubrication or maintenance needed
  • Quick and easy installation
  • Allows for 4-way flexing: angular, parallel, axial, and torsional 
  • Smooth operation and quiet performance 

MD Flex couplings are available in coupling sizes 3-14. Inserts are available in multiple materials, including EPDM, Neoprene, and Hytrel.

Jaw Couplings 

Jaw Couplings are an excellent choice for applications that require a low cost, general purpose coupling. They allow for a quick and easy shaft-to-shaft connection method. Solve’s portfolio of jaw type couplings provide efficient power transmission of torque, compensate for misalignment, and protect equipment from shock loads, enhancing overall machinery reliability. 

Jaw Couplings

Two coupling hubs are used in pairs with an elastomer element (spider), each sold separately. The element eliminates metal-to-metal contact and acts as a shock absorber. The design is considered "fail-safe" because if the element fails, the load would still be carried by the hubs.

Jaw couplings are available in sizes L035-L225. Available element materials include Buna-N (Rubber), Urethane, Hytrel, and Bronze.


  • All couplings are standard industry interchangeable
  • Black Phosphate treated for corrosion protection
  • Resistant to oil, dirt, sand, and grease

Solid Couplings 

Solid couplings are an easy and cost-effective method of connecting two shafts with different diameters. MasterDrive’s BCS Couplings are rigid all steel designs available in six configurations. They are designed to handle high torque, up to 14,600 in-lbs and do not have misalignment capability. All shaft connections are made with the bushed hubs.

Shaft Coupling Applications 

Applications include: 

  • HVAC/Air Handling: Used in motor-driven equipment like pumps, fans, and compressors to transmit power, reducing vibration and improving system efficiency.
  • Automation and Robotics: Employed in robotic systems and automated machinery to allow for movement and flexibility in joints and connections.
  • Material Handling Equipment: Used in equipment like forklifts and cranes to connect various moving parts and absorb shocks.
  • Agricultural Machinery: Employed in agricultural equipment such as harvesters and tractors to transmit power and accommodate misalignment.
  • Machine Tools: Applied in milling machines, lathes, and other machine tools to transmit power and accommodate misalignment, enhancing overall performance.
