Background

• Manyvehiclesnow have a system for opening and closing the automated tailgate using linear actuators and bearings.
• This automotive industry application is designed and produced according to ISO 16949.

Innovation JESA

• Bearing rings designed to withstand the stresses created by the over molding and shrinkage.
• Bearing internal design optimized for radial clearances for axial and radial loads.
• An advanced seal design “URS” that guarantees maximum sealing.
• Specific grease resistant to extreme temperatures found in automotive applications.

Solution JESA

• A special overmolded ball bearing with a high performance polymer. An “all in one“ solution.
• Adapted geometry of the molding to perfectly fit the ultrasonic welding process and with other parts of the system.
• JESA’s patented grooved outer ring ensures a perfect plastic to steel fit.
• Bearing designed to withstand heavy static and dynamic loads and to reduce the size and weight of the system.

Customer benefits

• A bespoke customer solution tailored to fit the other elements of the whole tailgate system.
• An overmolded bearing produced and design by Jesa, who are the specialist in mixed material solutions.
• The overmolding provides a lifetime attachment when compared to other methods of plastic to bearing steel (interference, by clip or circlip for example)
