NTN 7014CDBP5 is a matched pair of single-row angular contact ball bearings in the ISO 7014 size, ground for back-to-back mounting. Bore Diameter: 70 mm. Outside Diameter: 110 mm. Width: 20 mm per bearing. Total Width: 40 mm as a DB pair. Contact Angle: 15°. Precision Class: ABEC 5 / P5. Number Of Rows: 1 per bearing.
7014 — NTN single-row angular contact ball bearing, 70 series, 70 mm bore.
C — 15° contact angle.
DB — back-to-back matched pair. Two single-row bearings ground as a set. Not a double-row bearing.
P5 — ISO tolerance class 5, equivalent to ABEC 5.
The 15° angle favours radial stiffness and high speed. Back-to-back mounting takes axial load in both directions with high tilting stiffness, the standard arrangement for machine-tool spindles.
Fillet Radius r min: 1.1 mm. Fillet Radius r1 min: 0.6 mm. Effective Load Centre a: 22 mm per bearing. Shaft Abutment da min: 77 mm. Housing Abutment Da max: 103 mm.
Unit Quantity: 2 Pcs. One DB matched pair. Mounting Arrangement: Back-to-back (DB). Carton marking: 2MM9114 WI CR DB.
Cross-references: NSK 7014C and SKF 7014 CD, both 15° in a back-to-back pair at ABEC 5 / P5 class, and Fafnir 2MM9114WI CR DB, which is ABEC 7 / P4 class rather than P5.
