number of rows
also called row count · rows of rolling elements
HOW MANY ROWS OF ROLLING ELEMENTS THE BEARING CARRIES, as a numeral with a row unit. Published as its own criterion across the wheel-bearing trade and decisive in it: a SINGLE-row deep groove bearing takes axial load feebly and in one direction, a DOUBLE-row angular contact unit takes it hard in both, and that is the whole reason a car wheel uses the second. SKF's 6205-2RSH is one row; Koyo's DAC3874W-6CS84 is two, and the D in its DAC prefix stands for Double. A NUMERAL WITH A UNIT AND NOT A TOKEN [A14]: the pool's settled shape for a counted sub-part is a count unit (`u_electrode` on a spark plug's ground electrodes, `u_wheel` on a bin's castors, `u_slot`, `u_tier`, `u_tray`, `u_jar`, `u_seat`), and a four-row roller bearing exists in mill duty, so a two-value token would have been a false closure [A16]. Unstated on a plain bush, which has no rolling elements at all. Concern measurement.
Number of rows is a measured figure.
It belongs to measurement — its measurable, physical facts.
