This is an NTN 7008DBGNP5 angular contact ball bearing supplied as a matched back-to-back duplex pair. Each bearing measures Bore / Shaft Size: 40 mm, Outside Diameter: 68 mm, Overall Width: 15 mm, and the mounted pair stacks to a Total Width: 30 mm. Item weight: 0.210 kg (0.467 lb) per bearing. Rolling Elements: Ball. Number Of Rows: 1. Closure Type: Open. Seal type: Open. Bore Type: Straight. Material: High Carbon Chrome Steel. Design Units: Metric.
7008 — the ISO 7008 size, 40 x 68 x 15 mm; with no angle letter NTN builds it at 30°.
DB — back-to-back matched pair; the load lines diverge, giving the pair a wide effective spread and thrust capacity in both directions.
P5 — ISO Class 5, ABEC 5.
Contact Angle: 30°. Dynamic load rating: 18.80 kN (4,226 lbf). Static load rating: 14.60 kN (3,282 lbf). Limiting Speed: 10,000 rpm grease / 14,000 rpm oil. Precision Class: ISO Class 5. Precision rating: ABEC 5. Lubricant: Grease or oil. Max temp: 120 °C. Min temp: -40 °C. The steeper 30° angle shifts capacity toward axial load, and the Class 5 rings hold running accuracy across the speed range.
Shaft fillet radius r min: 1.0 mm. Second fillet radius r1 min: 0.6 mm. Shaft abutment da min: 45.5 mm. Housing abutment Da max: 62.5 mm. Housing abutment Db max: 63.5 mm. Effective load centre a: 23.0 mm.
Unit Quantity: 2 Pcs. Arrangement / Configuration: Matched back-to-back duplex pair (DB). Mounting Arrangement: Back-to-back (DB). The two bearings ship together as a ground and matched set.
Series: 70. Base Number: 7008. Part Number: 7008DBGNP5. MPN Variants: 7008, 7008DB, 7008-DB+16-GN-P5, 7008DBGNP5.
