Overmolded bearings

Optimize your applications with plastic

For a join to be durable, it must be perfect. For each application, the ideal synthetic material as well as an optimised design of the ball bearing overmolded by JESA facilitates a long life, high allowable loads, low wear and quiet operation. These benefits come from more than 40 years experience in the combination of ball bearings and plastic. The JESA engineering team analyses each application from A to Z in order to develop and manufacture a custom product that perfectly matches the specifications. With JESA's ease in the field of implementing plastics, special technical polymers, the precise profiles and complex shapes are the JESA capabilities serving the innovative industry.
