How the 22220 model number is decoded
The 22220 E is a 100×180×46 mm spherical roller bearing — the dimension series 22 (medium OD, wide) entry for a 100 mm shaft, with two rows of symmetrical barrel rollers for combined radial and axial load. Numbering ties the bearing to its envelope: 22220 means spherical-roller type, dimension series 22, 100 mm bore — which is why the 180×46 mm outline swaps dimensionally with other ISO 15 bearings of the same code. 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. Catalogue mass 4900 g for the 100×180×46 mm open execution covers the a stamped window-type steel cage; tapered-bore and sealed variants differ in mass and carry their own order numbers. Drive-on force must go through the ring being fitted: press or induction-heat the inner ring onto the 100 mm shaft (max 120 °C) and never transmit mounting force through the roller complement, or the raceways brinell.
Typical equipment & failure modes
Common applications
- marine propulsion and thruster shafts
- cement-mill trunnion and drive shafts
- heavy conveyor head shafts in mining
- jaw and cone crusher main 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 100 mm bore 22220 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 100 mm bore (180×46 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 22220; clearance reduction targets differ, and over-driving a cylindrical bore onto an oversized journal cracks the inner ring.
- The 4900 g mass and 46 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 22220.
- The 433/490 kN ratings are SKF catalogue values for this exact execution (22220 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 22220 (cylindrical bore as listed, tapered-bore 22220 EK variant, plus sealed and vibrating-screen options in the same envelope); they are not interchangeable order numbers — quote the full 22220 E designation when purchasing.
Frequently asked questions
What are the dimensions and catalogue data of 22220?
The 22220 E is a double-row spherical roller bearing with 100 mm bore, 180 mm outer diameter and 46 mm width (3.937 × 7.087 × 1.811 in) per ISO 15. From SKF catalogue PUB BU/P1 17000: basic dynamic load rating C 433 kN, C0 490 kN, fatigue load limit Pu 49 kN, reference speed 3,400 r/min, limiting speed 4,500 r/min, mass about 4900 g. It is an open, self-aligning bearing with a stamped window-type steel cage.
How does the 22220 bore code work?
The last two digits of 22220 are bore code 20, so 20 × 5 = 100 mm bore. The 180 mm OD and 46 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 22220?
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 22220 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 22220K 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 22220 listed here seats directly on a machined journal.
