LK Series Torsional Coupling
The LK Series coupling is a simple two-piece design consisting of an element and hub. The couplings are designed to be used with engine-driven, flange-mounted, hydraulic pump systems. The couplings are torsionally stiff, enabling hydraulic pumps and similar equipment with low mass or inertia to operate below critical speeds.
The torsionally stiff LK Series coupling raises the critical speed above the operating range, providing a system free of harmful torsional vibrations. The LK Series is ideal for hydrostatic drives on construction equipment, cranes, forklifts, excavators, vibratory rollers, tractors, etc. Virtually all engine-driven hydraulic systems in the low to mid-power range can use the LK Series coupling.
