Product Description
EP-GEG20C construction and application notes
EP-GEG20C is the 20 mm-bore model in the GE..C / GEG..C Maintenance-Free PTFE family. Its nominal envelope is d 20 mm × D 42 mm with B 25 mm overall width.
Outer ring pressed around the inner ring, with the outer race lined by PTFE composite material and a chromium-plated spherical inner-ring surface. The PTFE composite sliding layer removes routine relubrication from the bearing itself; load, oscillation, temperature and adjacent surface condition still control application suitability. On EP-GEG20C, that construction is paired with a 20 mm bore, 42 mm outside diameter, 25 mm overall width, 51 kN dynamic rating and 17° catalogue articulation value.
For EP-GEG20C, the C-family construction uses a PTFE-composite sliding layer instead of a routinely greased steel-on-steel contact. Selection should therefore focus on liner condition, motion, temperature and the surrounding surfaces as well as the basic boundary dimensions.
Installation and fit
For EP-GEG20C, 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-GEG20C in the joint
For EP-GEG20C, the useful starting point for this row is the physical interface: pin diameter, housing bore and available axial space. If the part is being measured from service, take several readings around the pin and housing before selecting the nominal envelope. Describe dust, water, wash-down or other exposure because the same dimensions can exist in constructions with different sealing strategies. For quotation, send the complete marking together with a joint photo and the measured interface.
