How the 22322 model number is decoded
SKF 22322 (22322 E) is the spherical-roller choice for a 110 mm shaft — barrel rollers between an inner ring with two raceways and a common sphered outer raceway inside the 240×80 mm ISO 15 envelope. On the SKF nameplate, 22322 follows the ISO 15 convention: 2 for the spherical roller type, 23 for the dimension series 23 (heavy OD, wide), final digits 22 for the 110 mm bore. The trailing E is the SKF optimized internal design: larger rollers and a stamped window-type steel cage give higher load ratings than the older CC geometry; EK is the same bearing with a 1:12 tapered bore for adapter sleeves. At 2,000 r/min reference speed the 65.0 mm-section 22322 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 2,800 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
- stamped-steel cage fatigue after long service in high-vibration screening duty without the VA405 execution
- roller-end scoring from starved lubricant at start-up before the grease channel purges
- hard-particle indentation of the raceway in unfiltered oil or contaminated grease systems
Selection pitfalls — read before you substitute
- Mount the 110 mm bore 22322 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 22300-series series at 110 mm bore (240×80 mm) is the heavy wide-section choice — highest capacity, lowest speed limit; do not substitute a 222 or 230 series in the same bore without re-checking both life and the 2,800 r/min ceiling.
- The 18500 g mass and 80 mm width mean abutment faces must be square to the axis within the bearing's own P0 tolerance; a tilted spacer tilts the outer ring and concentrates load on one roller row of 22322.
- The 22322 shares its ISO 15 envelope across brands, but internal geometry differs — SKF load ratings in this row are 989/1120 kN; another maker's same-size bearing may rate higher or lower, so do not interchange on envelope alone.
- The 989/1120 kN ratings are SKF catalogue values for this exact execution (22322 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 22322 (cylindrical bore as listed, tapered-bore 22322 EK variant, plus sealed and vibrating-screen options in the same envelope); they are not interchangeable order numbers — quote the full 22322 E designation when purchasing.
Frequently asked questions
What are the dimensions and catalogue data of 22322?
The 22322 E is a double-row spherical roller bearing with 110 mm bore, 240 mm outer diameter and 80 mm width (4.331 × 9.449 × 3.15 in) per ISO 15. From SKF catalogue PUB BU/P1 17000: basic dynamic load rating C 989 kN, C0 1120 kN, fatigue load limit Pu 100 kN, reference speed 2,000 r/min, limiting speed 2,800 r/min, mass about 18500 g. It is an open, self-aligning bearing with a stamped window-type steel cage.
How does the 22322 bore code work?
The last two digits of 22322 are bore code 22, so 22 × 5 = 110 mm bore. The 240 mm OD and 80 mm width come from the ISO 15 dimension-series plan (dimension series 23 (heavy OD, wide)), shared with other spherical roller bearings of the same code.
What does the E suffix mean on 22322?
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 22322 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 22322K 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 22322 listed here seats directly on a machined journal.
