How the 22212 model number is decoded
22212 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. Numbering ties the bearing to its envelope: 22212 means spherical-roller type, dimension series 22, 60 mm bore — which is why the 110×28 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. Selection arithmetic: the C0/C ratio is about 1.04 (static 166 kN against dynamic 159 kN), typical of a spherical roller sized for heavy combined loads, and the 18.6 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 22212 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
- 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
- brinelling from static overload or impact during handling and mounting
Selection pitfalls — read before you substitute
- Mount the 60 mm bore 22212 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 60 mm bore (110×28 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 22212; 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 22212; clearance reduction targets differ, and over-driving a cylindrical bore onto an oversized journal cracks the inner ring.
- The 159/166 kN ratings are SKF catalogue values for this exact execution (22212 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 22212 (cylindrical bore as listed, tapered-bore 22212 EK variant, plus sealed and vibrating-screen options in the same envelope); they are not interchangeable order numbers — quote the full 22212 E designation when purchasing.
Frequently asked questions
What are the dimensions and catalogue data of 22212?
The 22212 E is a double-row spherical roller bearing with 60 mm bore, 110 mm outer diameter and 28 mm width (2.362 × 4.331 × 1.102 in) per ISO 15. From SKF catalogue PUB BU/P1 17000: basic dynamic load rating C 159 kN, C0 166 kN, fatigue load limit Pu 18.6 kN, reference speed 5,600 r/min, limiting speed 7,500 r/min, mass about 1150 g. It is an open, self-aligning bearing with a stamped window-type steel cage.
How does the 22212 bore code work?
The last two digits of 22212 are bore code 12, so 12 × 5 = 60 mm bore. The 110 mm OD and 28 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 22212?
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 22212 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 22212K 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 22212 listed here seats directly on a machined journal.
