NTN 7205T2DB/GNP5 is a matched pair of single-row angular contact ball bearings in the ISO 7205 size, ground for back-to-back mounting. Bore Diameter: 25 mm. Outside Diameter: 52 mm. Width: 15 mm per bearing. Total Width: 30 mm as a DB pair. Contact Angle: 30°. Cage Material: Polyamide. Precision Class: ABEC 5 / P5.
7205 — NTN single-row angular contact ball bearing, 72 series, 25 mm bore. No angle letter: 30° contact angle.
T2 — polyamide (nylon) cage.
DB — back-to-back matched pair. Two single-row bearings ground as a set. Not a double-row bearing.
GN — NTN standard preload code for the matched set.
P5 — ISO tolerance class 5, equivalent to ABEC 5.
The 30° contact angle carries combined radial and axial load. Back-to-back mounting takes axial load in both directions and gives the pair high tilting stiffness. ABEC 5 tolerances suit machine-tool and precision spindle duty.
Unit Quantity: 2 Pcs. One DB matched pair. Mounting Arrangement: Back-to-back (DB).
Same envelope and 30° angle: NSK 7205A, Koyo 7205 and Nachi 7205 in DB, P5 execution. SKF and FAG 7205 B executions are 40° and do not share the contact angle.
