Decoding the designation

63 — the heavy dimension series, which puts a 170 mm outside diameter and a 39 mm width over an 80 mm bore.

16 — the bore code: 16 x 5 gives the 80 mm bore.

JN — pressed steel sheet metal cage.

CN — normal radial internal clearance.

What these specs mean in practice

The 63 heavy series carries a larger ball complement in a thicker section than a 62 or 60 bearing on the same shaft, so it takes markedly more radial load. Dynamic Load Rating: 131,000 N governs rotating life. Static Load Rating: 87,000 N sets the shock and stationary ceiling. Fatigue Load Limit: 5,400 N is the load below which fatigue life is effectively unlimited. Closure Type: open. With no seals or shields the bearing takes its lubricant from the housing, so it suits circulating oil, splash oil and central grease systems, and it relubricates freely. Operating Temperature: up to 150 °C, with the rings dimensionally stabilised to that figure. Internal Clearance: CN is the normal group, correct against a standard interference fit on the shaft and a standard housing bore.

Interchange guidance

6316 is the ISO designation for this 80 x 170 x 39 mm envelope and is carried across makers. Schaeffler lists 6316-C3, 6316-C4, 6316-2Z, 6316-2Z-C3, 6316-2RSR and 6316-2RSR-C3 in the same size; those change the clearance group and the closure and are related executions rather than like-for-like swaps. Searchable variants of the part number: 6316A, 6316 J, 6316 JEM, 316.
