How the 22215 model number is decoded
22215 E belongs to the SKF spherical roller range — the 75 mm bore entry in the 22200-series series (dimension series 22 (medium OD, wide)), dimensioned 130 mm OD and 31 mm wide. 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 75 mm bore; the 130 mm OD and 31 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. At 4,800 r/min reference speed the 27.5 mm-section 22215 is governed thermally by lubricant flow through the W33 groove and the two-row roller complement; grease or oil selection should be made against that value, with 6,300 r/min as the mechanical ceiling. Spherical roller bearings are routinely specified with C3 clearance because the tight inner-ring fit and inner/outer temperature gradient eat into the CN running clearance — check the residual clearance after mounting with feeler gauges.
Typical equipment & failure modes
Common applications
- heavy conveyor head shafts in mining
- jaw and cone crusher main shafts
- paper-machine press and dryer rolls
- rolling-mill pinion and back-up 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
- seal-lip wear and grease purge loss when an open bearing is run without functioning housing seals
Selection pitfalls — read before you substitute
- Mount the 75 mm bore 22215 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 75 mm bore (130×31 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.
- 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 22215 pits long before its L10 life.

- The 217/240 kN ratings are SKF catalogue values for this exact execution (22215 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 22215 (cylindrical bore as listed, tapered-bore 22215 EK variant, plus sealed and vibrating-screen options in the same envelope); they are not interchangeable order numbers — quote the full 22215 E designation when purchasing.
Frequently asked questions
What are the dimensions and catalogue data of 22215?
The 22215 E is a double-row spherical roller bearing with 75 mm bore, 130 mm outer diameter and 31 mm width (2.953 × 5.118 × 1.22 in) per ISO 15. From SKF catalogue PUB BU/P1 17000: basic dynamic load rating C 217 kN, C0 240 kN, fatigue load limit Pu 26.5 kN, reference speed 4,800 r/min, limiting speed 6,300 r/min, mass about 1700 g. It is an open, self-aligning bearing with a stamped window-type steel cage.
How does the 22215 bore code work?
The last two digits of 22215 are bore code 15, so 15 × 5 = 75 mm bore. The 130 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 22215?
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 22215 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 22215K 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 22215 listed here seats directly on a machined journal.
