SKF Jaw Coupling, 44.5mm Outside Diameter, 9mm Bore, 21mm Length Coupler

Use this jaw coupling from SKF to transmit torque and rotation between two mechanically connected shafts. The component's hub jaws are designed to mesh together, ensuring that the coupling will continue working even if the internal insert or spider fails. The spider itself is made of soft nitrile rubber, so it doesn't need lubrication. This material also increases the coupler's shock absorption and helps it dampen vibration for increased operator comfort.

• Bore size of 9 mm
• Coupling length of 21 mm
• Outer diameter of 44.5 mm
• Maintenance-free
• Easy installation
• Offers low vibration absorption and cushioning against moderate load shocks
• Able to withstand high rpm in applications with little or no misalignment

• Industrial manufacturing
• Agriculture and food production
• Automotive industry

Torsional movement, or misalignment, is the initial high torque caused during machinery startup that can force shafts out of alignment. A flexible coupling such as this one from SKF permits and compensates for limited amounts of misalignment.

Jaw couplings like this one are made with a soft elastomer (rubber) internal spider, which helps them absorb shocks and means there's no metal-to-metal contact between moving parts. They're also quieter in operation.
