Product Description

What this part is:

SKF 7004 CC/PA9B DT super-precision angular contact ball bearing set, a factory-matched tandem pair of two bearings. Open on both faces, one row of balls per bearing, fabric-base laminate phenolic cage. Unit Quantity: 2 Pc.

Decoding the designation:

7004 — ISO 70 light dimension series, 20 mm bore.

C — 15° contact angle.

DT — matched tandem set of two bearings.

2MMV9104WI CR DTL — the Timken Fafnir designation carried on the carton for the same bearing: 9104 is the ISO 70 series size 7004, 2MM is 15°, CR is the outer-land-riding phenolic cage, and DTL is a light-preload duplex tandem set.

Specifications:

Bore Diameter: 20 mm. Outside Diameter: 42 mm. Width: 12 mm per bearing; 24 mm across the pair. Contact Angle: 15°. Number Of Rows: 1 per bearing. Rolling Elements: Ball. Bore Type: Straight. Seal Type: Open. Cage Material: Fabric-base laminate phenolic. Material: Chrome Steel. Series: 7000. Base Number: 7004. Preload: Light. Dynamic Load Rating: 8.71 kN per bearing. Static Load Rating: 4.3 kN per bearing. Limiting Speed: 43 000 r/min. Precision Class: ABEC 9. Arrangement: Matched tandem set (DT). Unit Quantity: 2 Pc.

Dimensions and mounting:

Total width: 24 mm across the matched tandem pair. In a tandem set both bearings face the same direction, so their contact lines run parallel and the two share a single-direction thrust load. The set is ground for light preload.

Compatibility and replacement:

Cross-Reference 1: Fafnir 2MMV9104WI CR DTL, carton-marked for this set. Cross-Reference 2: FAG B7004-C-T-P2S, a P2 grade single bearing.
