Product Description

What this part is

NTN 7015CGD2GLP4 super-precision angular contact ball bearing. Series: 70. Bore: 75 mm. Outside diameter: 115 mm. Width per bearing: 20 mm. Open on both faces. Two pieces, factory matched as a universally matchable duplex pair.

Decoding the designation

7015 — ISO 70 series, 75 mm bore. C — Contact Angle: 15°. G — universally matchable: the ring faces are flush ground so any two bearings stack back-to-back, face-to-face or in tandem. GL — Preload: light. P4 — Precision Class: ABEC 7. The carton also carries the Fafnir designation 2MM9115WICR DUL, where DUL reads duplex, universally matchable, light preload.

What these specs mean in practice

A 15° contact angle favours speed and radial rigidity over thrust capacity. Dynamic Load Rating: 48.0 kN (10,800 lbf) per bearing. Static Load Rating: 45.5 kN (10,200 lbf) per bearing. Limiting Speed: 11,000 rpm on oil, 8,600 rpm on grease. Load centre: 22.5 mm. Operating temperature range: -40 to 120 °C. The phenolic cage is outer-ring-land-riding, which is what allows the high oil-lubricated speed.

Quantity and configuration

Two pieces. Mounted as a duplex pair the total width is 40 mm. Light preload gives lower heat generation and higher speed capability than a medium or heavy set on the same envelope.

Fitting notes

Bore form: round cylindrical, straight. Shaft backing shoulder da min 82.0 mm. Housing shoulder Da max 108.0 mm, Db max 110.5 mm. Chamfer limits r 1.1 mm and r1 0.6 mm. Lubrication: oil or grease. Item weight 1.80 lb (0.82 kg) per bearing.

Related part numbers

SKF 7015 CD/P4DGB (DGB is the light preload code; DGA is extra light and DGC medium) and FAG B7015-C-T-P4S-DUL are the equivalent 15° light-preload universally matchable executions on the same 75 x 115 x 20 mm envelope. Fafnir 2MM9115WICRDUL is the Timken/Fafnir equivalent. Searchable forms: 7015C GD2 GL P4, 7015-C-GD2-GL-P4, 7015 C GD2GL.
