Decoding the designation

618 — single-row deep groove ball bearing, ISO dimension series 18. The thinnest standard radial section, chosen where the housing bore is fixed and the shaft has to be as large as possible.

16 — bore code. Bore Diameter: 80 mm.

2RSR — contact lip seals on both faces, running on the inner ring. The bearing is grease filled for life.

Y — sheet brass cage.

Searchable forms of the designation: 61816-2RSR-Y, 618162RSRY, 61816-2RSR, 61816 2RSR Y, 6816-2RS, 6816.

What these specs mean in practice

Dynamic Load Rating: 13,800 N. Static Load Rating: 13,800 N. Fatigue load limit: 930 N. A 10 mm radial section limits how large the balls can be, so this series trades load capacity for a compact cross-section and a large bore.

Limiting Speed: 3,100 rpm. Contact lip seals hold grease in and contamination out, which is what sets the speed ceiling on a sealed bearing.

Closure Type: Contact lip seals both sides. The bearing arrives grease filled and runs for life with no relubrication path.

Operating temperature range published by Schaeffler: −20 °C to +100 °C. Calculation factor f0: 16.

A deep groove ball bearing carries radial load and axial load in both directions, and has no contact angle.
