igubal JEM SP – the versatile endurance runner

The JEM-SP bearing insert manufactured by injection moulding can be used in pillow block bearings and flange bearings. It consists of the high-performance polymer iglidur J, which is characterized by particularly low wear, a long service life and low moisture absorption.

Thanks to the embedded solid lubricant, no additional lubrication is required, which makes operation in dirty environments particularly advantageous. Our bearing inserts are easy to install and offer a cost-effective and lightweight alternative to a conventional metallic ball bearing.

In our shop you will also find flange bearings and pillow block bearings with plastic housings, which have a positive effect on the overall weight of your plant.

As a PTFE-free alternative, we also offer our injection-molded bearing inserts made of iglidur J3: J3EM-SP
