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 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 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.
