NTN 7209DB is a matched pair of single-row angular contact ball bearings ground for back-to-back mounting. Bore Diameter: 45 mm. Outside Diameter: 85 mm. Width: 19 mm per bearing. Total Width: 38 mm (pair). Contact Angle: 30°. Mounting Arrangement: Back-to-back (DB). Closure Type: Open.
7209 — ISO 72 series (light section), bore code 09, 45 x 85 x 19 mm. No angle letter: 30° contact angle.
DB — back-to-back matched pair. Two single-row bearings ground as a set. Not a double-row bearing.
The 30° angle balances radial and axial capacity. Back-to-back mounting spreads the load centres apart, giving the pair high moment stiffness and axial location in both directions, as used on pump, gearbox and machine spindles.
Fillet Radius r: 1.1 mm. Fillet Radius r1: 0.6 mm. Shaft Abutment da min: 52 mm. Housing Abutment Da max: 78 mm.
Unit Quantity: 2 Pcs. One matched DB pair.
Cross-Reference: Koyo 7209DB and NSK 7209ADB, 30° back-to-back pairs on the same 45 x 85 x 19 mm envelope.
