Couplings

Joyce offers a variety of couplings to meet your system requirements. Choose the type that is best for your application.

Coupling Selection:

Model S Coupling    Image preview
Joyce Model S geared couplings offer greater torque capacity than jaw couplings. More gear teeth around the inner circumference, plus high tensional, radial and angular stiffness mean that you get a more durable coupling. These are available in flex/ rigid and flex/flex configurations. 

Model F Coupling (shown to right)
Joyce Model F geared couplings offer greater torque capacity than jaw couplings. More gear teeth around the inner circumference, plus high tensional, radial and angular stiffness mean that you get a more durable coupling. These offer superior radial-misalignment capability and radial flexibility.

Model J Coupling  Image preview
Model J couplings are ideal for many general industrial applications, require no lubrication, and are resistant to oil, grease, moisture and other contaminants.

 

Ordering Information:

Couplings are important components in jack and actuator systems and it is important to select the best option based on torque and rotational speed requirements. Contact sales@joycedayton.com with your questions and allow us to help you specify the compatible components for a complete system. Otherwise refer to the list of part numbers for each coupling.
