How the 22222 model number is decoded
22222 E belongs to the SKF spherical roller range — the 110 mm bore entry in the 22200-series series (dimension series 22 (medium OD, wide)), dimensioned 200 mm OD and 53 mm wide. The code breaks down as type digit 2 (double-row spherical roller), dimension series 22 (dimension series 22 (medium OD, wide)), and bore code 22 = 110 mm; dimensions 110×200×53 mm therefore match the ISO 15 envelope. 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. Speed planning uses two different ceilings: 3,000 r/min thermal reference and 4,000 r/min mechanical limiting speed. After mounting, swing the outer ring to confirm free self-alignment: the 22222 should tilt through its full catalogue misalignment range without binding; a stiff joint signals a cocked seat or shoulder interference.
Typical equipment & failure modes
Common applications
- paper-machine press and dryer rolls
- rolling-mill pinion and back-up shafts
- large vibrating screens and feeders
- marine propulsion and thruster 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
- cage pocket wear or fracture from roller skew at insufficient minimum load or rapid acceleration
- roller-end scoring from starved lubricant at start-up before the grease channel purges
- electrical pitting on VFD-driven shafts without grounding protection
Selection pitfalls — read before you substitute
- Mount the 110 mm bore 22222 by induction heating (max 120 °C) or oil injection — driving a bearing of this section home through the rollers brinells both raceways, and the damage only speaks up as vibration hours later.
- The 22200-series series at 110 mm bore (200×53 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.
- Catalogue reference speed and limiting speed are different limits: the 3,000 r/min reference is a thermal criterion under load, while the 4,000 r/min limiting value is the mechanical ceiling — observe both.
- The self-aligning feature is not a license to ignore alignment: beyond ≈ 0.5–2.5° (series-dependent) the edge loading eats the fatigue margin, and seal drag grows as the rings tilt.
- The 572/640 kN ratings are SKF catalogue values for this exact execution (22222 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 22222 (cylindrical bore as listed, tapered-bore 22222 EK variant, plus sealed and vibrating-screen options in the same envelope); they are not interchangeable order numbers — quote the full 22222 E designation when purchasing.
Frequently asked questions
What are the dimensions and catalogue data of 22222?
The 22222 E is a double-row spherical roller bearing with 110 mm bore, 200 mm outer diameter and 53 mm width (4.331 × 7.874 × 2.087 in) per ISO 15. From SKF catalogue PUB BU/P1 17000: basic dynamic load rating C 572 kN, C0 640 kN, fatigue load limit Pu 63 kN, reference speed 3,000 r/min, limiting speed 4,000 r/min, mass about 7000 g. It is an open, self-aligning bearing with a stamped window-type steel cage.
How does the 22222 bore code work?
The last two digits of 22222 are bore code 22, so 22 × 5 = 110 mm bore. The 200 mm OD and 53 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 22222?
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 22222 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 22222K 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 22222 listed here seats directly on a machined journal.
