The Ministerial Decree No. 246/2025 (5 page(s), in Arabic) mandating the Egyptian Standard ES 4861 " Rolling bearings — Cylindrical roller bearings, separate thrust collars — Boundary dimensions "; (9 page(s), in English)

The Ministerial Decree No. 246/2025 gives the producers and importers a six-month transitional period to abide by the Egyptian standard ES 4861 which specifies the width, the maximum outside diameter, the bore and the bore minimum chamfer of separate thrust collars for cylindrical roller bearings in diameter series 0, 2, 3, and 4 as specified in ISO 15.

Dimensions for overall width and other geometrical features are not specified as they are dependent on the internal design of the bearings. Worth mentioning is that this standard adopts the technical content of ISO 246:2007.
