An NSK 7008CTYDULPA7 super-precision angular contact ball bearing set, 40 mm bore, 68 mm outside diameter, 15 mm width per bearing. It is a matched duplex pair, ground to run together as one unit.
7008 — 70-series single-row angular contact, 40 x 68 x 15 mm
C — 15° contact angle in the NSK scheme
TY — moulded polyamide cage
DUL — duplex, light preload
PA7 — ABEC 7, equivalent to ISO P4
A 15° contact angle favours speed and radial rigidity over thrust capacity; a 25° bearing in the same envelope trades speed away for more axial load. Light preload keeps running temperature and friction down while still removing axial play, which is why this combination is standard on machine-tool spindles and precision ballscrew ends. The polyamide cage runs quietly and tolerates high speed, with a continuous service ceiling around 120 °C.
Two bearings, supplied as one matched duplex pair. The pair is ground as a set and the preload is only correct when both rings are mounted together in the marked orientation.
The bearings seat against a square, clean shaft shoulder and housing face, with the V-marks or match marks on the outer rings lined up. Duplex sets are clamped solid against their abutments; no shimming is used to set preload, because the preload is already built into the ground faces.
Fafnir 2MM9108WI-DUL and FAG B7008C.T.P4S.DUL are 15°, P4-class, light-preload duplex 7008 sets. SKF 7008 CD/P4ADGA has the same angle and class with extra light preload. 25° variants such as the 7008A5 and 3MM9108WI series, and any single universal (SU) bearing, share the 40 x 68 x 15 mm size but are different parts.
