This technical diagram defines the essential dimensions and geometric variables for the correct housing and installation of the UIB3 rod seal. It specifies the critical dimensions linked to the data tables, including the seal width (b), the groove width (B), the rod inner diameter (Ød) and the housing outer diameter (ØD). It also details the geometric specifications of the bottom and edge radii (r and r1), the extrusion gap (E), as well as the length (C) and the 20° angle of the lead-in chamfer (rounded and free of burrs). These values ensure perfect alignment, prevent pinching or damage to the sealing lips during installation and guarantee efficient, long-lasting sealing under demanding pressure conditions.
