Decoding the designation

63 — single-row deep groove ball bearing, ISO dimension series 03. The heavy section carries a larger ball set than a 62-series bearing on the same bore.

15 — bore code. Bore Diameter: 75 mm.

2RS1 — SKF nitrile rubber contact seals on both faces, running on the inner ring. The bearing arrives grease filled.

Searchable forms of the designation: 6315-2RS1, 6315RS, 6315-2RS, 63152RS1, 6315 2RS1.

What these specs mean in practice

Dynamic Load Rating: 119,000 N. Static Load Rating: 76,500 N. This is an SKF Explorer performance class bearing, which is SKF’s upgraded steel and surface finish specification on the same boundary dimensions.

Limiting Speed: 2,800 rpm. A contact seal rubs the inner ring land, and that friction is what sets the speed ceiling on a sealed bearing.

Closure Type: Contact seals both sides. Sealing keeps the grease in and contamination out, which is the usual reason a sealed 6315 is chosen over an open one for electric motors, fans, pumps and gearbox shafts.

Internal Clearance: CN, the normal class. A deep groove ball bearing carries radial load and axial load in both directions, and has no contact angle.

Interchange guidance

Cross-Reference 1: SKF 6315-2RS1. Cross-Reference 2: FAG 6315-2RSR. Cross-Reference 3: NSK 6315DDU. Cross-Reference 4: NTN 6315LLU. Cross-Reference 5: Timken / Fafnir 315PP. Cross-Reference 6: RHP 6315-2RS. Cross-Reference 7: Koyo 6315-2RS. Cross-Reference 8: MRC 315SZZ. Cross-Reference 9: SNR 6315EE.

All nine share the 75 x 160 x 37 mm envelope of ISO series 6300 and carry contact seals on both faces, so they are direct substitutions. On MRC the ZZ suffix denotes rubber seals rather than shields, which is why the 315SZZ belongs in this list.
