How the 22210 model number is decoded
SKF 22210 (22210 E) is the spherical-roller choice for a 50 mm shaft — barrel rollers between an inner ring with two raceways and a common sphered outer raceway inside the 90×23 mm ISO 15 envelope. Reading the designation: the leading 2 marks a spherical roller bearing, the 22 is the ISO 15 dimension series (dimension series 22 (medium OD, wide)), and the last two digits encode the 50 mm bore; the 90 mm OD and 23 mm width follow the ISO 15 general plan. In SKF suffix language, E marks the optimized high-capacity design and CC/W33 the pressed-steel-cage execution with relubrication groove; both are open bearings — the sealed variant carries the 2CS5 suffix and the vibrating-screen execution VA405. With C 107 kN and C0 108 kN, the 22210 load check covers radial plus moderate axial in either direction — but below the minimum load the rollers skid, so verify P ≥ 0.01·C0 at the lightest operating point. A 50 mm rotating inner ring usually runs k5 on the shaft with H7 in the housing; for vibrating-screen duty the outer ring is instead held tight and the shaft seat loosened — follow the screen builder's fit schedule.
Typical equipment & failure modes
Common applications
- centrifugal pump and fan shafts
- hammer-mill and crusher rotors
- continuous-caster guide rolls
- extruder gearbox shafts
Known failure patterns
- raceway fatigue spalling of the sphered outer raceway after extended service above the catalogue L10 rating
- inner-ring raceway spalling from edge loading when misalignment exceeds the self-aligning recovery range
- stamped-steel cage fatigue after long service in high-vibration screening duty without the VA405 execution
- surface distress and smearing when the relubrication interval is exceeded — the W33 groove is only effective if grease actually reaches the roller rows
- smearing on the roller-raceway contact during skid starts below the minimum load
Selection pitfalls — read before you substitute
- On this 50 mm bore, an interference inner-ring fit consumes a large share of the CN clearance; specify C3 when the inner ring rotates hot, and verify residual clearance after mounting rather than trusting the catalogue clearance class.
- The 22200-series series at 50 mm bore (90×23 mm) is the general-purpose spherical roller envelope; stepping up to 223 adds capacity and width, stepping to 230 trims the OD — neither is interchangeable without re-checking shoulders and speed.
- Shaft and housing fillets must clear the bearing chamfer so the 23 mm-wide rings seat square; use an undercut or withdrawal groove rather than an oversized radius that locks on the ring face.

- The 107/108 kN ratings are SKF catalogue values for this exact execution (22210 E); SKF can revise internal geometry without changing the order number, so keep the catalogue version (SKF catalogue PUB BU/P1 17000) with the specification and re-verify for critical drives.
- SKF lists several executions of 22210 (cylindrical bore as listed, tapered-bore 22210 EK variant, plus sealed and vibrating-screen options in the same envelope); they are not interchangeable order numbers — quote the full 22210 E designation when purchasing.
Frequently asked questions
What are the dimensions and catalogue data of 22210?
The 22210 E is a double-row spherical roller bearing with 50 mm bore, 90 mm outer diameter and 23 mm width (1.969 × 3.543 × 0.906 in) per ISO 15. From SKF catalogue PUB BU/P1 17000: basic dynamic load rating C 107 kN, C0 108 kN, fatigue load limit Pu 11.8 kN, reference speed 7,000 r/min, limiting speed 9,500 r/min, mass about 630 g. It is an open, self-aligning bearing with a stamped window-type steel cage.
How does the 22210 bore code work?
The last two digits of 22210 are bore code 10, so 10 × 5 = 50 mm bore. The 90 mm OD and 23 mm width come from the ISO 15 dimension-series plan (dimension series 22 (medium OD, wide)), shared with other spherical roller bearings of the same code.
What does the E suffix mean on 22210?
E is the SKF optimized internal design with larger rollers and a stamped window-type steel cage for higher load ratings. The EK variant is the same bearing with a 1:12 tapered bore for adapter sleeves.
Can 22210 accommodate misalignment and axial load?
Yes on both counts. The sphered outer raceway lets the bearing self-align ≈ 0.5–2.5° depending on series, absorbing shaft deflection and housing-seat errors. The two barrel-roller rows also carry bidirectional axial load in addition to heavy radial load — this is the key difference from cylindrical roller bearings, which take no axial load.
When should the tapered-bore 22210K variant be used instead?
Choose the K (1:12 tapered bore) variant when the bearing must seat on an adapter or withdrawal sleeve — typical for long shafts, frequent dismounting, or stepped shafts where machining a precision journal is impractical. Sleeve mounting requires measuring clearance reduction or axial drive-up, not nut torque. The cylindrical-bore 22210 listed here seats directly on a machined journal.
