igubal J3EM-SD – Bearing insert with seal for use in demanding environments
The igubal bearing insert with integrated seal has been specially developed for applications in dirty and abrasive environments. This lubrication-free plastic alternative to conventional UC tension bearings offers high wear resistance and reliable protection against ingress of dirt particles.
The machined bearing insert is made from the high-performance plastic iglidur J3 and is fitted with an iglidur A160 seal on one or both sides. The integrated sealing ring prevents dust, dirt, and other abrasive particles from entering the moving contact area between the bearing and the shaft, significantly reducing wear.
Material properties iglidur J3
