A single-row super-precision angular contact ball bearing in the 72-series, 75 mm bore, 125 mm outside diameter, 24 mm width. It is universally ground, so any two bearings of the same designation stack into a matched set at the specified light preload in back-to-back, face-to-face or tandem arrangement.

A 15° contact angle gives high speed capability and strong radial stiffness with moderate thrust capacity, which is the standard choice for the front and rear positions of a machine tool spindle. Light preload keeps friction and heat generation low and allows the highest running speed of the preload classes, trading away some axial rigidity relative to medium or heavy.
The phenolic cage runs quietly at speed and holds lubricant in its laminate structure. P4Y accuracy holds tight bore and outside diameter tolerance with low radial and axial runout, and the universal grind means the faces are finished so that stacked bearings reach the stated preload without shims or spacers.
Single bearing, 1 Pc. Universally ground for use alone or stacked with identical bearings as a duplex, triplex or quad set.
The wide outer-ring shoulder takes thrust, so orientation sets the load direction. Multiple bearings assemble with their marked faces aligned to the intended arrangement, clamped between a square shaft shoulder and a precision lock nut. Shaft and housing seats to the accuracy grade the P4 class assumes preserve the ground runout.
Closest matches are 15° universally ground light-preload P4 bearings in the same size: RHP 7214CTSULP4 and FAG B7214-C-T-P4S-UL. SKF 7214 CD/P4A is a near part with the same 15° P4A size, with preload set by the suffix. A 7214 in A5 or A form carries a 25° or 30° contact angle, and a SUM or SUH variant carries medium or heavy preload; those are related sizes rather than interchanges.
