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.

2RSR — contact lip seals on both sides, Schaeffler’s seal code.

C3 — radial internal clearance greater than normal.

JN — pressed steel sheet metal cage.

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: contact seals both sides. The seals hold the factory grease charge in and keep dust, coolant and washdown out for the life of the bearing. Typical duty is conveyors, fans, crushers and outdoor drives. The rubbing lips cost some running torque, which is why the Limiting Speed of this sealed execution is 2,470 rpm.

Internal Clearance: C3 gives more room than normal before the balls are preloaded. That headroom absorbs a heavy interference fit on the shaft and the temperature difference between the inner and outer ring, which is why C3 is specified on hot and hard-driven shafts.

Interchange guidance

6316 is the ISO designation for this 80 x 170 x 39 mm envelope and is carried across makers: SKF 6316-2RS1/C3 and NSK 6316DDUC3 are the same size with contact seals and C3 clearance. Schaeffler lists 6316, 6316-C3, 6316-2RSR, 6316-2Z and 6316-2Z-C3 on the same envelope; those change the clearance group or the closure and are related executions. Searchable variants of the part number: 6316.2RSR.C3, 6316-2RSR-C3, 6316 2RSR C3, 63162RSRC3, 6316 2RS C3.
