Guardian™ DELTA Series Flywheel Couplings
Guardian DELTA Series flywheel couplings are engineered for diesel-driven hydrostatic machinery and construction equipment, offering a cost-effective and durable solution. Its single-piece design integrates a hardened steel hub with a reinforced flange, reducing installation time and eliminating extra fasteners. Elastomeric grommets provide steady vibration damping while maintaining stiffness, allowing low-inertia equipment to operate safely below critical speed ranges.

Guardian™ Guard-Flex™ Flywheel Couplings
Guardian Guard-Flex flywheel couplings are designed for construction applications where vibration damping and equipment protection are critical. Its torsionally soft, in-shear design acts as a mechanical fuse, safeguarding both the engine and driven equipment in overload conditions. With elastomer options in 45, 55, and 65 shore A durometers, the coupling can be tailored to provide the right balance of stiffness and damping for pumps, compressors, and other construction machinery.

Guardian™ FBA Series Flywheel Couplings
Guardian FBA Series flywheel couplings are built for rugged construction applications, offering a one-piece, all-steel design that ensures strength and durability. They attach directly to the engine flywheel for quick installation, with no hub positioning required, allowing hydraulic pumps to be blind fitted into the coupling hub. Elastomeric grommets provide steady damping of engine vibrations while minimizing side loading on the pump shaft, protecting equipment in demanding environments.

Guardian™ Pump Flanges
Guardian™ Pump Flanges provide versatile, durable mounting solutions for SAE and metric pumps, with customization available for unique installation needs. Each steel plate includes a rust‑protective coating and comes in multiple thicknesses to support varied applications. Standard options cover SAE sizes 1 through 6, with SAE 0 and 00 available upon request, along with plain or zinc finishes and additional coating choices such as e‑coat, black oxide, and powder coat.

Guardian™ FL Series Flywheel Couplings
Guardian FL Series flywheel couplings are a proven, economical solution for off-highway construction equipment such as skid steer loaders, aerial lifts, and excavators. With decades of success in the field, this two-piece design combines a glass-reinforced nylon flywheel flange that fits both SAE and metric flywheels with a sintered steel hub for use on splined or straight shafts. The torsionally stiff construction requires no lubrication and is interchangeable with other popular coupling brands, making it both reliable and versatile.

CENTAFLEX™-K Flywheel Couplings
CENTAFLEX™-K series is a compact two-piece coupling with high torsional stiffness and resonance-free operation. Ideally suited for hydrostatic driven construction equipment, lower-horsepower applications are easily handled by the CENTAFLEX-K.
