How the 22319 model number is decoded
In SKF catalogue PUB BU/P1 17000, 22319 appears as 22319 E: an open, double-row spherical roller bearing, self-aligning by virtue of the sphered outer raceway, sized 95×200×67 mm to the ISO 15 boundary plan. On the SKF nameplate, 22319 follows the ISO 15 convention: 2 for the spherical roller type, 23 for the dimension series 23 (heavy OD, wide), final digits 19 for the 95 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. The 73.5 kN Pu figure feeds the adjusted-life equation at contaminated or partial-film conditions, and the 1.09 C0/C balance shows this execution is tuned to heavy radial-plus-axial duty with misalignment tolerance. Drive-on force must go through the ring being fitted: press or induction-heat the inner ring onto the 95 mm shaft (max 120 °C) and never transmit mounting force through the roller complement, or the raceways brinell.
Typical equipment & failure modes
Common applications
- cement-mill trunnion and drive shafts
- heavy conveyor head shafts in mining
- jaw and cone crusher main shafts
- paper-machine press and dryer 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
- roller-end scoring from starved lubricant at start-up before the grease channel purges
- rolling-contact fatigue spalling after the rated L10 life is exceeded
Selection pitfalls — read before you substitute
- Mount the 95 mm bore 22319 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 95 mm bore (200×67 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 3,400 r/min ceiling.
- The 22319 shares its ISO 15 envelope across brands, but internal geometry differs — SKF load ratings in this row are 699/765 kN; another maker's same-size bearing may rate higher or lower, so do not interchange on envelope alone.
- 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 22319 pits long before its L10 life.
- The 699/765 kN ratings are SKF catalogue values for this exact execution (22319 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 22319 (cylindrical bore as listed, tapered-bore 22319 EK variant, plus sealed and vibrating-screen options in the same envelope); they are not interchangeable order numbers — quote the full 22319 E designation when purchasing.
Frequently asked questions
What are the dimensions and catalogue data of 22319?
The 22319 E is a double-row spherical roller bearing with 95 mm bore, 200 mm outer diameter and 67 mm width (3.74 × 7.874 × 2.638 in) per ISO 15. From SKF catalogue PUB BU/P1 17000: basic dynamic load rating C 699 kN, C0 765 kN, fatigue load limit Pu 73.5 kN, reference speed 2,600 r/min, limiting speed 3,400 r/min, mass about 10500 g. It is an open, self-aligning bearing with a stamped window-type steel cage.
How does the 22319 bore code work?
The last two digits of 22319 are bore code 19, so 19 × 5 = 95 mm bore. The 200 mm OD and 67 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 22319?
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 22319 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 22319K 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 22319 listed here seats directly on a machined journal.
