LORD engineers can assist you with selecting an appro-

priate coupling type and confi guration. With extensive 

analytical capability and years of experience in designing 

products for powertrain vibration, shock and motion 

control, LORD engineers offer everything from simple 

application assistance to complex system analysis and 

specialized product design.

Torsional vibration, transient shock and misalignment 

load analyses require specialized computer programs 

and engineering experience. LORD engineers can 

analyze your system and recommend the right solution, 

whether it’s a selection from the standard product line or 

a custom design.

LORD Corporation’s standard product lines of elasto-

meric fl exible powertrain couplings are presented in the 

following sections. Many variations of standard products 

are available, but not listed as ‘standard.’ Main drive, fan 

drive, PTO and accessory drive couplings are available 

in a host of custom designs and variations of standard 

products. LORD engineers are ready to help you meet 

your specifi c application requirements with custom 

designs where necessary.

LORD offers fi ve major lines of elastomeric fl exible 

couplings. Standard lines are presented on the following 

pages. In addition to the standards listed, many 

variations are available in each product line.

LORD Dynafl ex Shear-Type Coupling features a durable 

elastomeric fl exing element bonded between two hubs. 

These couplings are designed for fractional horsepower 

applications requiring smooth starting transition, torsional 

vibration isolation and misalignment accommodation. 

Typical applications are small electric motor drives, 

low-torque mechanisms, power take-offs and auxiliary 

equipment drives.

®

LORD Dynafl ex Spool-Type Couplings can be arranged 

in a variety of confi gurations to create a wide range 

of torque-transmitting capability. Elastomeric spool 

elements can be purchased in lot sizes for customer-

assembled coupling designs, or LORD can provide a 

complete coupling assembly to meet specifi c application 

requirements. Typical applications are large drives 

requiring high torque capacity and low torsional stiffness.

®

LORD Dynafl ex Bushing-Type Couplings are bonded 

elastomeric elements designed for use in multiple 

element coupling confi gurations where high torque 

capacity is required. Bushings are available in a 

variety of stiffnesses. They can be purchased in lots for 

customer-assembled designs, or LORD can provide 

complete coupling assemblies designed to meet your 

specifi c application requirements. Applications requiring 

high torque/high torsional stiffness, but angular, axial and 

parallel misalignment accommodation can be designed 

using these bushings in a variety of confi gurations  

including parallel and series arrangements.

®

LORD Dynafl ex LCR Series Couplings features an 

elastomeric ring with bonded, bush-type inserts allowing 

various attachment confi gurations. These couplings 

offer a soft torsional spring rate which permits smooth 

transmission of driving torque while attenuating 

shock torques and providing excellent misalignment 

accommodation. These couplings are used in PTO 

drives where torsion and cocking fl exibility are required. 

They can be mated with a variety of hub confi gurations. 

Special high-torque designs are available, as well 

as custom designs to meet special application 

requirements.

®

LORD Dynafl ex LCD Series Couplings are the ultimate 

coupling for reciprocating engine drives. This coupling 

features a bonded elastomeric fl exing element which is 

radially precompressed into a fl anged outer housing. 

This design produces a low torsional stiffness for 

maximum isolation of engine fi ring-pulse-induced 

torsional disturbances, torque overload slip protection, 

misalignment accommodation, superior shock pulse 

attenuation and fatigue life, and is adaptable to a variety 

of drive attachment designs. Custom designs are 

available to fi t nearly every SAE fl ywheel confi guration 

available from most engine manufacturers.
