How the 22214 model number is decoded
In SKF catalogue PUB BU/P1 17000, 22214 appears as 22214 E: an open, double-row spherical roller bearing, self-aligning by virtue of the sphered outer raceway, sized 70×125×31 mm to the ISO 15 boundary plan. The code breaks down as type digit 2 (double-row spherical roller), dimension series 22 (dimension series 22 (medium OD, wide)), and bore code 14 = 70 mm; dimensions 70×125×31 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. Catalogue mass 1550 g for the 70×125×31 mm open execution covers the a stamped window-type steel cage; tapered-bore and sealed variants differ in mass and carry their own order numbers. For relubrication, route the grease duct to the outer-ring W33 groove position where fitted, and purge until fresh grease appears at the seal — the 31 mm width across two roller rows needs the full charge.
Typical equipment & failure modes
Common applications
- marine propulsion and thruster shafts
- cement-mill trunnion and drive shafts
- heavy conveyor head shafts in mining
- jaw and cone crusher main 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
- Mount the 70 mm bore 22214 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 70 mm bore (125×31 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 5,000 r/min reference is a thermal criterion under load, while the 6,700 r/min limiting value is the mechanical ceiling — observe both.
- Catalogue reference speed and limiting speed are different limits: the 5,000 r/min reference is a thermal criterion under load, while the 6,700 r/min limiting value is the mechanical ceiling — observe both.
- The 213/228 kN ratings are SKF catalogue values for this exact execution (22214 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 22214 (cylindrical bore as listed, tapered-bore 22214 EK variant, plus sealed and vibrating-screen options in the same envelope); they are not interchangeable order numbers — quote the full 22214 E designation when purchasing.
Frequently asked questions
What are the dimensions and catalogue data of 22214?
The 22214 E is a double-row spherical roller bearing with 70 mm bore, 125 mm outer diameter and 31 mm width (2.756 × 4.921 × 1.22 in) per ISO 15. From SKF catalogue PUB BU/P1 17000: basic dynamic load rating C 213 kN, C0 228 kN, fatigue load limit Pu 25.5 kN, reference speed 5,000 r/min, limiting speed 6,700 r/min, mass about 1550 g. It is an open, self-aligning bearing with a stamped window-type steel cage.
How does the 22214 bore code work?
The last two digits of 22214 are bore code 14, so 14 × 5 = 70 mm bore. The 125 mm OD and 31 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 22214?
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 22214 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 22214K 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 22214 listed here seats directly on a machined journal.
