The off-highway vehicle market is evolving rapidly, with trends such as larger machines, increased horsepower, idle management systems, higher engine temperatures, and hybrid drive options pushing the need for advanced elastomeric powertrain couplings.
In response, Parker has developed LORD Next-Gen Elastomeric Couplings. This innovative design features a high-temperature elastomeric element combined with coil springs and snubbing pads, providing multiple stiffness stages tailored to inertia. This ensures optimal isolation and durability throughout the vehicle's operating range.

Elastomeric flexible couplings prolong driveline component life because they reduce the magnitude of imposed loads, attenuate vibration in multiple planes, accommodate misalignments in multiple planes, and act as barriers impeding noise created by meshing gears, engaging clutches, etc. Elastomeric flexible couplings are also maintenance free. They require no lubrication or other maintenance throughout their service life.
Our Fluidlastic Mounts provide superior cab damping and motion control that decreases noise and vibration, and increases operator safety and comfort across a variety of severe-duty applications.
Application of Elastomeric Flexible Couplings
Application requirements dictate the flexible coupling style needed to optimize powertrain performance and component longevity. Misalignment accommodation, torsional vibration isolation, transient shock dissipation and required service life are important parameters to consider when selecting a torsional coupling to fill specific application requirements.
Learn more about how powertrain component life is determined by the load spectrum each component will experience during the machine’s service life.
Shear-Type Couplings are compact, one-piece flexible couplings economically constructed to isolate low-frequency vibration and accommodate multi-directional misalignment. These couplings are ideally suited for fractional horsepower drivelines demanding noise reduction, vibration isolation and maintenance-free operation.
Rated: 1/50 to 1 hp at 1750 rpm
Spool-Type Flexible Couplings provide low frequency vibration isolation in high torque drive systems. These couplings are customer-assembled using bonded flexing spools bolted between customer-supplied metal hubs. Shear spool-type couplings provide excellent protection against destructive torsional vibration.
Rated: 5 to 1000 hp at 2000 rpm
Bushing-Type Flexible Couplings accommodate misalignment, cushion torsional shock and do not generate or transmit noise. Since relative motion is taken in the elastomer no lubricant is involved or ever required. Dirt and grit cannot effect the coupling bushings. These couplings are relatively stiff torsionally compared to other elastomeric couplings.
Rated: 10 to 600 hp at 2000 rpm
LCR Highly Flexible Couplings offer a soft torsional spring rate which attenuates shock torques and provides excellent misalignment accomodation. These ring-type, highly flexible, rubber couplings are easy to install, eliminate lubrication and maintenance, reduce noise transmission, and increase bearing and driveline life.
Rated: 4 to 135 hp at 2000 rpm
LCD Torsionally Flexible Flywheel Couplings were developed to overcome numerous torsional problems associated with vehicular and industrial driveline systems. These couplings provide maximum isolation of engine firing pulse induced disturbances, torque overload slip protection, and superior shock pulse attenuation and fatigue life.
Rated: 75 to 2000 hp at 2000 rpm
If you work in the construction or forestry sector, heavy equipment represents a significant portion of your capital investment. This equipment takes a rigorous beating during everyday operations, threatening not only your investment but your ability to meet demand. What should you look for when you buy equipment like this? What can help extend the life of your equipment and reduce time-consuming, costly repairs?
We previously talked about how important it is to insist on flexible couplings when you purchase heavy equipment. Continuous vibration and intermittent shocks can cause numerous difficulties – from gear tooth fatigue to broken driveshafts—and flexible couplings can prevent these problems by reducing the vibration transmitted to downstream components.
