Pillow block bearings differ from other self-adjusting bearings due to the housing unit used. Two screws are provided for fastening the pillow block bearings in place. Exact alignment is not necessary in this case as the spherical bearing can compensate for misalignments thanks to its ability to spherically adjust itself. Edge loads as well as tilting and bending of shafts are also avoided. The main areas of use for our pillow block bearings are therefore applications in which such problems cannot be prevented by means of the way in which the equipment is designed. igubal® pillow block bearings do not need any lubricant thanks to the special materials used. This ensures maintenance-free dry operation without any problems, even in dirty environments.
