2. Engineering fit - Wikipedia

   en.wikipedia.org/wiki/Engineering_fit

   Engineering fits are generally used as part of geometric dimensioning and tolerancing when a part or assembly is designed. In engineering terms, the "fit" is the clearance between two mating parts, and the size of this clearance determines whether the parts can, at one end of the spectrum, move or rotate independently from each other or, at the other end, are temporarily or permanently joined.

3. End-face mechanical seal - Wikipedia

   en.wikipedia.org/wiki/End-face_mechanical_seal

   The mating ring can contain the seal face diameters, although this is not a requirement of the mating ring. To minimize primary ring motion, the mating ring must be mounted solidly and should form a perpendicular plane for the primary ring to run against. Like seal rings, mating rings are available in many different shapes. [1]
