RHP 7016CTDUHP4 super-precision angular contact ball bearing. Bore 80 mm, outside diameter 125 mm, width 22 mm. Straight bore, open on both faces, single row of balls, machined phenolic cage.
70 is the ISO light angular contact dimension series and 16 is the bore code, giving an 80 mm bore. C denotes a 15° contact angle in the RHP scheme. T is a fabric-base laminate phenolic cage. DU marks the bearing as a universally ground duplex unit and H sets heavy preload. P4 is ISO Class 4, equivalent to ABEC 7. The carton also carries 2MM9116WI CR DUH and B7016X2TADUHEP7, whose 2MM and X2 codes independently confirm the 15° angle and whose EP7 confirms the ABEC 7 class.
A 15° contact angle favours speed and radial stiffness over thrust capacity, which is the usual choice for a high-rpm grinding or milling spindle. The phenolic cage is light and self-lubricating, raising the speed ceiling above a steel cage. Heavy preload maximises stiffness and running accuracy at the cost of some speed and additional heat generation. ISO Class 4 controls bore, outside diameter and raceway runout to super-precision limits.
One piece. The -1/2PR designation identifies a single bearing out of a pair. Universal grinding means any two units of the same designation stack directly as a back-to-back, face-to-face or tandem set with the preload built into the ground faces.
Ring faces are ground flat and square for direct abutment, so preload develops when the shaft nut and housing cap are drawn fully home. Phenolic cages suit oil mist and light grease charges.
Same 15° equivalents are the SKF 7016 CD/P4A, the FAG B7016-C-T-P4S and the NSK 7016CTYNDUHP4. Cage material differs across those numbers, which changes the published speed rating.
