An NHBB ME-1206DL matched duplex pair of super-precision angular contact spindle bearings. Each bearing has a 30 mm bore, a 62 mm outside diameter and a 16 mm width, giving a 32 mm stack height for the pair. The ME-1206 size maps to the 7206 envelope.
ME: NHBB metric spindle bearing series. 1206: 7206 envelope, 30 mm bore, 62 mm OD, 16 mm width. D: duplex universally ground. L: light preload.
A 15° contact angle keeps the load line close to the radial plane, limiting centrifugal ball loading and raising the practical speed ceiling — the standard angle for high-speed spindles. Light preload keeps frictional heat and power draw low, so the spindle stays thermally stable over long cycles, in exchange for less axial stiffness than a medium or heavy set. Universal grinding means the ring faces are finished so the two bearings clamp into a light-preload set without shimming, in back-to-back, face-to-face or tandem orientation.
Bore: 30 mm (1.1811 in). Outside diameter: 62 mm (2.4409 in). Width per bearing: 16 mm (0.6299 in). Total width as a pair: 32 mm (1.2598 in). Contact angle: 15°. Preload: light (L). Precision class: P4, ABEC 7. Number of rows: 1 per bearing. Rolling elements: steel balls. Closure: open. Arrangement: duplex universally ground pair.
Supplied as 2 Pcs, a matched duplex pair.
Orientation sets the behaviour: back-to-back or face-to-face carries thrust in both directions and resists tilting, while tandem carries thrust in one direction at doubled capacity.
Genuine equivalents are 15° ABEC 7 universally ground light-preload pairs in the same 30x62x16 mm envelope: FAG 7206-C-TPA-P4-DUL, NSK 7206CTRDULP4, SKF 7206 CD/P4ADGA in light preload, RHP 7206CTDULP4 and Fafnir 2MM206WI-DUL. The 25° build of this size is a related size rather than an interchange, and medium or heavy preload versions change spindle stiffness and running temperature.
