Precision bearings

Standard design



Standard bushes for slide bearings are manufactured with the highest precision of all ZEDEX high-performance plastics. There are over 2000 dimensions in the range of 2mm to 250mm available for shaft diameters.

Depending on the requirements out of 4 bearing clearance classes (coarse, regular, fine and negative) are selected. (see table Classes of bearing clearances)

The available dimensions can be found in our bearings catalog in PDF format.

Take the free advice our technical services. We put on the plastic storage needs and provide you with a bearing capacity and service life calculation.
