Product Description

What this part is:

FAG B7217-C-B-P4S-DUL is a matched pair of super-precision angular contact spindle bearings from the Schaeffler B72 series. Bore Diameter: 85 mm. Outside Diameter: 150 mm. Width: 28 mm per bearing. Contact Angle: 15°. Precision Class: ABEC 7 / P4S. Preload: Light.

Decoding the designation:

B7217 — FAG spindle bearing, ISO 7217 envelope, 85 x 150 x 28 mm.

C — 15° contact angle.

P4S — Schaeffler restricted-tolerance class: P4 dimensional accuracy with tighter running accuracy.

DUL — two universally matched bearings with light preload, mountable back-to-back, face-to-face or in tandem.

What these specs mean in practice:

Dynamic Load Rating: 97,000 N per bearing. Static Load Rating: 59,000 N per bearing. Preload Force: Light, 568 N (Schaeffler FV L). Operating Temperature: -30 to 100 °C. The heavier 72 series section carries more load than the 70 series at the same bore.

Mounting data:

Shaft Shoulder Diameter: 98 mm. Housing Shoulder Diameter: 138 mm. Item Weight: 1.78 kg (3.93 lb) per bearing.

Quantity and configuration:

Unit Quantity: 2 Pcs. One universally ground matched pair. New old stock.

Cross-references:

At 15°, P4 class and light preload: Fafnir 2MM217WI DUL and RHP 7217CTDULP4. SKF 7217 CD/P4ADGA matches the angle and grade at extra light preload. The current Schaeffler designation B7217-C-T-P4S-UL is sold as a single bearing rather than a pair.
