internal clearance
also called clearance class · radial play
THE RADIAL SLACK BETWEEN THE RINGS BEFORE THE BEARING IS FITTED, as the standard class the maker designates - C2, normal (CN/C0), C3, C4, C5. SKF describes the 6205-2RSH as `normal clearance (C0)` and lists the 6205-2RSH/C3 as a separate article. THAT PAIR IS THE WHOLE ARGUMENT [A13]: same type, same 25 x 52 x 15, same double contact seal, same 14.8 kN and 7.8 kN, same 8500 r/min - identical in every other field this class holds - and they are two catalogue numbers at two prices, because a shaft that is an interference fit or a housing that runs hot closes a normal clearance to nothing. Without this slot they are ONE STATEMENT in this grammar, which is the b155 B6ES/BP6ES defect and the b157 SI 5900/SI 5910 defect, caught here by the generator's own completeness check at the moment of the fold rather than by the adversary afterwards [H2-f16]. A CLOSED PUBLISHED SCALE AND NOT A HOUSE'S PRIVATE NUMBERING, so unlike b155's `heat_range` it needs no scale qualifier: ISO 5753 fixes the ranges in micrometres per bore band and every maker uses the same letters. Concern measurement.
Internal clearance is answered with one word chosen from the internal clearance classes list — the same word shared across every product that uses it.
It belongs to measurement — its measurable, physical facts.
