Product Description

What this part is

SNFA EX50-7CE1DUL is a matched set of two super-precision single-row angular contact ball bearings from the SNFA EX high-capacity series, ISO dimension series 10. Bore Diameter: 50 mm. Outside Diameter: 80 mm. Width: 16 mm per bearing. Contact Angle: 15°. Precision Class: ABEC 7 / P4. The closest SKF high-capacity D design pair is the 7010 CD/P4ADGA, at extra light rather than light preload.

Decoding the designation

EX — SNFA high-capacity angular contact series, ISO dimension series 10 (70xx envelope).

50 — bore diameter in millimetres.

7 — SNFA precision grade, ABEC 7 (ISO P4).

C — phenolic resin cage.

E — cage centred on the outer ring.

1 — 15° contact angle.

DU — universal duplex set: two bearings ground for back-to-back, face-to-face or tandem mounting.

L — light preload.

What these specs mean in practice

Dynamic Load Rating: 29,600 N per bearing. Static Load Rating: 24,000 N per bearing. Limiting Speed: 17,000 rpm grease; 28,000 rpm oil-air, single bearing. The 15° angle favours radial stiffness and speed; light preload keeps heat generation low.

Mounting data

Item Weight: 0.249 kg (0.55 lb) per bearing. Cage Type: Outer-ring guided. Cage Material: Phenolic. Closure Type: Open.

Quantity and configuration

Unit Quantity: 2 Pcs. Mounting Arrangement: Universal matched pair, back-to-back, face-to-face or tandem. Preload: Light.

Interchange guidance

SKF owns SNFA and lists the EX series alongside its 70 .. CD range. Parts with the same 50 x 80 x 16 mm size and 15° contact angle: NSK 7010CTRDULP4 and Fafnir 2MM9110WICRDUL are light preload pairs (the Fafnir is P4S tolerance). FAG B7010-C-T-P4S-UL is a single bearing at light preload. SKF 7010 CD/P4ADGA and SKF 7010 CDGA/P4A are extra light preload, the first a pair and the second a single bearing.
