How the 22216 model number is decoded
For a 80 mm shaft carrying heavy radial load with misalignment or deflection, SKF lists 22216 under catalogue execution 22216 E: two barrel-roller rows on a sphered outer raceway. Digit by digit, 22216 reads as bearing type 2 (spherical roller, two barrel-roller rows), dimension series 22, and bore reference 16 resolving to 80 mm; 140 mm OD and 33 mm width are the matching ISO 15 boundary values. 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. Speed planning uses two different ceilings: 4,300 r/min thermal reference and 6,000 r/min mechanical limiting speed. Drive-on force must go through the ring being fitted: press or induction-heat the inner ring onto the 80 mm shaft (max 120 °C) and never transmit mounting force through the roller complement, or the raceways brinell.
Typical equipment & failure modes
Common applications
- paper-machine press and dryer rolls
- rolling-mill pinion and back-up shafts
- large vibrating screens and feeders
- marine propulsion and thruster 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
- brinelling from static overload or impact during handling and mounting
Selection pitfalls — read before you substitute
- Mount the 80 mm bore 22216 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 80 mm bore (140×33 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 22216 shares its ISO 15 envelope across brands, but internal geometry differs — SKF load ratings in this row are 243/270 kN; another maker's same-size bearing may rate higher or lower, so do not interchange on envelope alone.
- The 22216 shares its ISO 15 envelope across brands, but internal geometry differs — SKF load ratings in this row are 243/270 kN; another maker's same-size bearing may rate higher or lower, so do not interchange on envelope alone.
- The 243/270 kN ratings are SKF catalogue values for this exact execution (22216 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 22216 (cylindrical bore as listed, tapered-bore 22216 EK variant, plus sealed and vibrating-screen options in the same envelope); they are not interchangeable order numbers — quote the full 22216 E designation when purchasing.
Frequently asked questions
What are the dimensions and catalogue data of 22216?
The 22216 E is a double-row spherical roller bearing with 80 mm bore, 140 mm outer diameter and 33 mm width (3.15 × 5.512 × 1.299 in) per ISO 15. From SKF catalogue PUB BU/P1 17000: basic dynamic load rating C 243 kN, C0 270 kN, fatigue load limit Pu 29 kN, reference speed 4,300 r/min, limiting speed 6,000 r/min, mass about 2100 g. It is an open, self-aligning bearing with a stamped window-type steel cage.
How does the 22216 bore code work?
The last two digits of 22216 are bore code 16, so 16 × 5 = 80 mm bore. The 140 mm OD and 33 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 22216?
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 22216 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 22216K 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 22216 listed here seats directly on a machined journal.
