Decoding the designation

B719 — Schaeffler’s spindle bearing series in the extra-light 719 section, which puts a large bore inside a small outside diameter.

71915 — ISO size code. Bore 75 mm, outside diameter 105 mm, width 16 mm.

C — Contact angle 15°.

TPA — Fabric-base laminate phenolic cage, machined.

P4S — Precision Class: ABEC 7 / P4.

UL — Universally matchable. Faces are ground so any two or more bearings pair in back-to-back, face-to-face or tandem arrangement and reach the published preload without shims.

What these specs mean in practice

Dynamic Load Rating: 35,000 N. Static Load Rating: 24,200 N. Limiting Speed: 13,000 rpm grease; 20,000 rpm oil. Fatigue load limit, radial: 2,550 N.

Precision Class: ABEC 7 / P4. Cage Material: Phenolic. Cage Type: Machined. Lubricant: grease or oil. Operating temperature range: -30 °C to +100 °C.

The 30 mm wall between a 75 mm bore and a 105 mm outside diameter is what defines the 719 section: it fits where a 70-section bearing will not, at a lower load rating. Series: B719. Base Number: B71915.
