RHP 7016 T.DUL.P4 super-precision angular contact ball bearing. Bore Diameter: 80 mm. Outside Diameter: 125 mm. Overall Width: 22 mm. Precision Class: ABEC 7 / P4. Cage Material: Phenolic. Closure Type: Open. Number Of Rows: 1. Bore Type: Straight. Unit Quantity: 1 Pc. Universally ground for duplex mounting at light preload.
7016 — ISO 70 series single-row angular contact ball bearing, 80 mm bore, 125 mm outside diameter, 22 mm width.
T — phenolic (laminated fabric) cage. Light, self-lubricating and quiet at speed.
DU — duplex universally ground. Any two pieces of the same designation stack to a defined preload in any orientation. DU is the duplex form; SU is the single form.
L — light preload. RHP’s scale runs L light, M medium, H heavy.
P4 — ISO tolerance class 4, equivalent to ABEC 7. RHP also writes this class EP7, which is why the title carries 7016TDUEP7.
-1/2PR — half a pair. One bearing.
1 Pc. The -1/2PR suffix marks one half of a pair. Universally ground faces let this bearing run as a single or match with another bearing of the same designation in back-to-back (DB), face-to-face (DF) or tandem (DT) arrangement, with the ground offsets setting a light preload without shims or spacers.
Preload removes internal clearance, which raises axial and radial stiffness and keeps the balls from skidding at high speed. Light preload is the high-speed choice: lower heat generation and less stiffness than medium or heavy preload. The phenolic cage weighs a fraction of a brass cage, retains oil and runs quietly. P4 / ABEC 7 tightens bore, outside diameter, width and runout tolerances for running accuracy.
RHP’s bearing business became part of NSK, so NSK 7016 super-precision is the current-brand series. MM9116WI-CR-DUL is carried on this listing as the Fafnir / Timken designation for the 80 x 125 x 22 mm envelope with phenolic cage and duplex light preload. The same 7016 envelope is also produced in a medium-preload duplex (DUM) and a single universally ground (SU) execution.
