Interchange notes
A 6213 candidate must match 65×120×23 mm. Do not select by the 120 mm OD alone: 6311 shares that OD but has a 55 mm bore and 29 mm width.
For 6213, verified contact-seal codes include SKF 2RSH, NSK DDU, FAG/INA 2RSR, NTN LLU, KOYO/Timken 2RS and NACHI 2NSE. The shield codes shown are 2Z, ZZ, 2ZR or ZE depending on manufacturer.
Manufacturer checks before substitution
Confirm load rating, speed limit, internal clearance, precision class, lubrication and application suitability in the official manufacturer catalog for the exact brand and suffix. This page does not supply those values or make an application recommendation. Review the interchange rules before selecting a substitute.

FAQ
What are the ISO 15 dimensions for 6213?
The boundary dimensions are d = 65 mm bore, D = 120 mm outside diameter and B = 23 mm width.
How do SKF 6213-2RSH and NSK 6213-DDU relate?
They are the SKF and NSK contact-seal suffix forms represented in the verified table. The suffixes are not universal codes; confirm each exact catalog entry.
Are 6213 and 6311 interchangeable because both are 120 mm OD?
No. The 6213 is 65×120×23 mm and the 6311 is 55×120×29 mm, so their bore and width differ.
Related sizes
Boundary-dimension cross-reference only. Per the applicable ISO standard (ISO 15 for ball, ISO 355 for tapered), the boundary dimensions are common across brands, so the mounting envelope is interchangeable. This is NOT a drop-in part equivalence. Internal clearance, precision class, seal/shield type (where applicable), cage material and factory lubrication are encoded in brand-specific suffixes and must be matched separately. Always verify against the manufacturer's catalog before substituting.
