What is the difference between a jaw coupling and a gear coupling?

Jaw couplings use an elastomeric spider to absorb shock and are best for light to medium duty. Gear couplings have higher torque capacity and accommodate larger misalignment, suitable for heavy industrial applications like steel mills.

How to select the right fluid coupling for a conveyor?

Consider motor power (kW), output speed, and starting load. Raydafon provides a free sizing tool – contact our engineers with your drive parameters.
