Machinable Bore Flexible Shaft Coupling
Manufacturer part: 3530N318
Customize the bore of these flexible couplings to align uncommon shaft sizes as well as shafts that have become undersized from wear or oversized from coatings. Also known as Lovejoy® couplings, these three-piece couplings have a spider-shaped cushion between two hubs to reduce shock and handle minor shaft misalignment. A complete coupling consists of two hubs and one spider (all components sold separately). Fasten to your shaft with set screws (not included), which bite into the shaft for a secure hold. If the spider fails, the hubs will lock together, giving you time to shut down your equipment to prevent component damage and replace the spider. These couplings do not need lubrication.Polyurethane spiders can run at a higher torque than Buna-N spiders, but do not offer as much vibration damping. Use them for continuous motion. Similar to Buna-N, they resist oil and chemicals.
