How the 22205 model number is decoded
22205 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. On the SKF nameplate, 22205 follows the ISO 15 convention: 2 for the spherical roller type, 22 for the dimension series 22 (medium OD, wide), final digits 05 for the 25 mm bore. 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. The 4.75 kN Pu figure feeds the adjusted-life equation at contaminated or partial-film conditions, and the 0.88 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 25 mm shaft (max 120 °C) and never transmit mounting force through the roller complement, or the raceways brinell.
Typical equipment & failure modes
Common applications
- compactor and roller vibratory drums
- woodworking machine cutter spindles
- small vibrating screens and sieve shafts
- agricultural elevator and auger 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
- surface distress and smearing when the relubrication interval is exceeded — the W33 groove is only effective if grease actually reaches the roller rows
- smearing on the roller-raceway contact during skid starts below the minimum load
Selection pitfalls — read before you substitute
- At a 25 mm bore the small barrel rollers skid readily at light load; keep the radial load above the minimum (roughly 0.01·C0) and avoid long idling at speed — unloaded 22205 rows scuff the raceway before fatigue ever shows.
- The 22200-series series at 25 mm bore (52×18 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.
- The self-aligning feature is not a license to ignore alignment: beyond ≈ 0.5–2.5° (series-dependent) the edge loading eats the fatigue margin, and seal drag grows as the rings tilt.
- Catalogue reference speed and limiting speed are different limits: the 13,000 r/min reference is a thermal criterion under load, while the 17,000 r/min limiting value is the mechanical ceiling — observe both.
- The 49.9/44 kN ratings are SKF catalogue values for this exact execution (22205 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 22205 (cylindrical bore as listed, tapered-bore 22205 EK variant, plus sealed and vibrating-screen options in the same envelope); they are not interchangeable order numbers — quote the full 22205 E designation when purchasing.
Frequently asked questions
What are the dimensions and catalogue data of 22205?
The 22205 E is a double-row spherical roller bearing with 25 mm bore, 52 mm outer diameter and 18 mm width (0.984 × 2.047 × 0.709 in) per ISO 15. From SKF catalogue PUB BU/P1 17000: basic dynamic load rating C 49.9 kN, C0 44 kN, fatigue load limit Pu 4.75 kN, reference speed 13,000 r/min, limiting speed 17,000 r/min, mass about 260 g. It is an open, self-aligning bearing with a stamped window-type steel cage.
How does the 22205 bore code work?
The last two digits of 22205 are bore code 05, so 05 × 5 = 25 mm bore. The 52 mm OD and 18 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 22205?
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 22205 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 22205K 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 22205 listed here seats directly on a machined journal.
