Product Description
EP-GEG20ES construction and application notes
EP-GEG20ES is the 20 mm-bore model in the GEG..E / GEG..ES Heavy-Duty family. Its nominal envelope is d 20 mm × D 42 mm with B 25 mm overall width.
Heavy-duty GEG radial construction with a single axial split. Type ES uses lubricating grooves and holes in both rings. The 17° articulation value shown in the model table helps define angular movement around the spherical sliding surface. This construction is intended for slow oscillating or pivoting joints where a planned lubrication path is available. On EP-GEG20ES, that construction is paired with a 20 mm bore, 42 mm outside diameter, 25 mm overall width, 48.0 kN dynamic rating and 17° catalogue articulation value.
For EP-GEG20ES, the GEG heavy-duty family uses a wider radial section than the comparable GE range. Housing width and shoulder support therefore deserve extra attention when a machine needs the heavier GEG envelope but remains on a greaseable steel-on-steel system.
Installation and fit
For EP-GEG20ES, start the fit review from its 20 mm bore and 42 mm outside diameter, then check how the 25 mm bearing width is supported by the housing shoulders. The fitting-tolerance resource includes H7 and h6 among the reference classes; final fit still depends on ring loading, housing stiffness, temperature and the machine interface.
Selection Context
How to verify EP-GEG20ES in the joint
For EP-GEG20ES, for a replacement check, begin with the joint envelope and then compare the full bearing marking. If the part is being measured from service, take several readings around the pin and housing before selecting the nominal envelope. For protected machinery, focus on motion and maintenance access; for exposed machinery, add sealing and contamination to the same review. Include quantity and application with the dimensional data so the response can distinguish a one-off replacement from a repeat requirement.
