How the 22207 model number is decoded
In SKF catalogue PUB BU/P1 17000, 22207 appears as 22207 E: an open, double-row spherical roller bearing, self-aligning by virtue of the sphered outer raceway, sized 35×72×23 mm to the ISO 15 boundary plan. 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 35 mm bore; the 72 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. The 18.5 mm radial section height ((72−35)/2) and 450 g catalogue mass frame a 35 mm bore bearing rated at 88.8 kN C — roughly 2.54 kN of dynamic capacity per millimetre of bore before application factors. After mounting, swing the outer ring to confirm free self-alignment: the 22207 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
- industrial gearbox output shafts
- centrifugal pump and fan shafts
- hammer-mill and crusher rotors
- continuous-caster guide rolls
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
- brinelling from static overload or impact during handling and mounting
Selection pitfalls — read before you substitute
- On this 35 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 35 mm bore (72×23 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.
- Open spherical roller bearings rely on the housing seals; in screening or crusher duty a failed seal lets grit into the sphered raceway and the 22207 pits long before its L10 life.
- The 22207 shares its ISO 15 envelope across brands, but internal geometry differs — SKF load ratings in this row are 88.8/85 kN; another maker's same-size bearing may rate higher or lower, so do not interchange on envelope alone.
- The 88.8/85 kN ratings are SKF catalogue values for this exact execution (22207 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 22207 (cylindrical bore as listed, tapered-bore 22207 EK variant, plus sealed and vibrating-screen options in the same envelope); they are not interchangeable order numbers — quote the full 22207 E designation when purchasing.
Frequently asked questions
What are the dimensions and catalogue data of 22207?
The 22207 E is a double-row spherical roller bearing with 35 mm bore, 72 mm outer diameter and 23 mm width (1.378 × 2.835 × 0.906 in) per ISO 15. From SKF catalogue PUB BU/P1 17000: basic dynamic load rating C 88.8 kN, C0 85 kN, fatigue load limit Pu 9.3 kN, reference speed 9,000 r/min, limiting speed 12,000 r/min, mass about 450 g. It is an open, self-aligning bearing with a stamped window-type steel cage.
How does the 22207 bore code work?
The last two digits of 22207 are bore code 07, so 07 × 5 = 35 mm bore. The 72 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 22207?
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 22207 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 22207K 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 22207 listed here seats directly on a machined journal.
