Splined Flexible Shaft Coupling Hub

Manufacturer part: 9843T101

Connect splined shafts to keyed shafts. These couplings are commonly used to connect hydraulic pumps, compressors, and other heavy duty equipment, which often have splined shafts, to electric motors and other components that often have keyed shafts. They have a splined hub on one side and a keyed hub on the other. A spider cushion in the middle damps vibration, absorbs shock loads, and adjusts for misalignment. Because the hubs interlock with the spider, these couplings will continue to work even if the spider breaks or wears away. This fail-safe design gives you time to shut down your power source before damage occurs to other components. Lubrication is not required.A complete coupling consists of two hubs and one spider. All components are sold separately.Buna-N spiders are best for high-speed systems and jobs with frequent starting, stopping, and reversing. The most commonly used spider material, Buna-N absorbs vibration better than other materials but cannot handle as much torque. It won't break down when exposed to oil and chemicals.
