RHP 7204CTSUMP4 super-precision single-row angular contact ball bearing, 20 mm bore, 47 mm outside diameter, 14 mm width. Steel balls, phenolic cage, open on both faces, straight bore.
72 is the ISO dimension series and 04 is the bore code — 4 × 5 = 20 mm. In the RHP scheme the C is a 15° contact angle, the T is a phenolic cage, SU marks a single universally ground ring, M calls medium preload and P4 is the tolerance class, equal to ABEC 7.
A 15° contact angle favours speed and radial stiffness; a 25° ring in the same 20 x 47 x 14 mm envelope carries more thrust and turns slower. Medium preload sits between the light class chosen for maximum speed and the heavy class chosen for maximum rigidity. The phenolic cage is light, quiet and rated to 120 °C, and it tolerates thin oil films.
A single row of angular contact balls takes thrust in one direction, toward the high shoulder of the outer ring. Universal grinding means any two of these rings assemble back-to-back, face-to-face or in tandem with no shims. Back-to-back and face-to-face pairs locate the shaft both ways; a tandem pair remains one direction and shares the thrust.
1 Pc. Single bearing, universally ground, medium preload class.
The face mark on one ring sets the resulting arrangement when two rings are stacked. Interference on the shaft and housing seats adds to preload, so those seats are ground to spindle tolerances rather than to a nominal 20 mm and 47 mm.
The equivalent 15° single-universal designations at this envelope are the FAG B7204-C-T-P4S-UM and the SKF 7204 CDGB/P4A. The Timken Fafnir 2MM204WI CR SUL is the same 15° single-universal geometry in the light preload class, so it is a related designation rather than an identical part. A 7204E or plain 7204 of this envelope carries a different contact angle and is a related size.
