How the 22219 model number is decoded
22219 is a double-row spherical roller bearing in the 22200-series family: two rows of barrel rollers on a common sphered outer raceway, self-aligning under shaft deflection, listed by SKF in SKF catalogue PUB BU/P1 17000. The code breaks down as type digit 2 (double-row spherical roller), dimension series 22 (dimension series 22 (medium OD, wide)), and bore code 19 = 95 mm; dimensions 95×170×43 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. Selection arithmetic: the C0/C ratio is about 1.15 (static 450 kN against dynamic 393 kN), typical of a spherical roller sized for heavy combined loads, and the 45.5 kN fatigue load limit Pu is the equivalent-load floor used in the life calculation. The cylindrical-bore execution here seats directly on the shaft journal; if the application calls for an adapter sleeve, order the tapered-bore 22219 EK variant instead and measure the drive-up or clearance reduction, not the nut torque.
Typical equipment & failure modes
Common applications
- jaw and cone crusher main shafts
- paper-machine press and dryer rolls
- rolling-mill pinion and back-up shafts
- large vibrating screens and feeders
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 95 mm bore 22219 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 95 mm bore (170×43 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.
- Never use the tapered-bore EK/K variant's drive-up figures on this cylindrical-bore 22219; clearance reduction targets differ, and over-driving a cylindrical bore onto an oversized journal cracks the inner ring.
- Never use the tapered-bore EK/K variant's drive-up figures on this cylindrical-bore 22219; clearance reduction targets differ, and over-driving a cylindrical bore onto an oversized journal cracks the inner ring.
- The 393/450 kN ratings are SKF catalogue values for this exact execution (22219 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 22219 (cylindrical bore as listed, tapered-bore 22219 EK variant, plus sealed and vibrating-screen options in the same envelope); they are not interchangeable order numbers — quote the full 22219 E designation when purchasing.
Frequently asked questions
What are the dimensions and catalogue data of 22219?
The 22219 E is a double-row spherical roller bearing with 95 mm bore, 170 mm outer diameter and 43 mm width (3.74 × 6.693 × 1.693 in) per ISO 15. From SKF catalogue PUB BU/P1 17000: basic dynamic load rating C 393 kN, C0 450 kN, fatigue load limit Pu 45.5 kN, reference speed 3,600 r/min, limiting speed 4,800 r/min, mass about 4150 g. It is an open, self-aligning bearing with a stamped window-type steel cage.
How does the 22219 bore code work?
The last two digits of 22219 are bore code 19, so 19 × 5 = 95 mm bore. The 170 mm OD and 43 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 22219?
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 22219 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 22219K 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 22219 listed here seats directly on a machined journal.
