How the 23022 model number is decoded
For a 110 mm shaft carrying heavy radial load with misalignment or deflection, SKF lists 23022 under catalogue execution 23022 CC/W33: two barrel-roller rows on a sphered outer raceway. Digit by digit, 23022 reads as bearing type 2 (spherical roller, two barrel-roller rows), dimension series 30, and bore reference 22 resolving to 110 mm; 170 mm OD and 45 mm width are the matching ISO 15 boundary values. SKF basic executions here are E or CC/W33; specialist suffixes change the bearing materially — VA405 for vibrating screens (C4 clearance, surface-hardened cage), 2CS5 for the sealed variant — and must be quoted in full when ordering. Catalogue mass 3800 g for the 110×170×45 mm open execution covers the two pressed-steel cages with a floating guide ring; tapered-bore and sealed variants differ in mass and carry their own order numbers. After mounting, swing the outer ring to confirm free self-alignment: the 23022 should tilt through its full catalogue misalignment range without binding; a stiff joint signals a cocked seat or shoulder interference.
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
- surface distress and smearing when the relubrication interval is exceeded — the W33 groove is only effective if grease actually reaches the roller rows
- false brinelling on standby machines exposed to external vibration
Selection pitfalls — read before you substitute
- Mount the 110 mm bore 23022 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 23000-series series at 110 mm bore (170×45 mm) is the slim-OD envelope: it buys radial space but gives up capacity against a 222-series bearing of the same bore — confirm the L10 margin before downsizing into it.
- The 23022 shares its ISO 15 envelope across brands, but internal geometry differs — SKF load ratings in this row are 326/440 kN; another maker's same-size bearing may rate higher or lower, so do not interchange on envelope alone.
- Shaft and housing fillets must clear the bearing chamfer so the 45 mm-wide rings seat square; use an undercut or withdrawal groove rather than an oversized radius that locks on the ring face.
- The 326/440 kN ratings are SKF catalogue values for this exact execution (23022 CC/W33); 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 23022 (cylindrical bore as listed, tapered-bore 23022 CCK/W33 variant, plus sealed and vibrating-screen options in the same envelope); they are not interchangeable order numbers — quote the full 23022 CC/W33 designation when purchasing.
Frequently asked questions
What are the dimensions and catalogue data of 23022?
The 23022 CC/W33 is a double-row spherical roller bearing with 110 mm bore, 170 mm outer diameter and 45 mm width (4.331 × 6.693 × 1.772 in) per ISO 15. From SKF catalogue PUB BU/P1 17000: basic dynamic load rating C 326 kN, C0 440 kN, fatigue load limit Pu 46.5 kN, reference speed 3,400 r/min, limiting speed 4,300 r/min, mass about 3800 g. It is an open, self-aligning bearing with two pressed-steel cages with a floating guide ring.
How does the 23022 bore code work?
The last two digits of 23022 are bore code 22, so 22 × 5 = 110 mm bore. The 170 mm OD and 45 mm width come from the ISO 15 dimension-series plan (dimension series 30 (slim OD, extra-wide)), shared with other spherical roller bearings of the same code.
What does the CC/W33 suffix mean on 23022?
CC denotes two pressed-steel cages with a floating guide ring between the roller rows, and W33 adds an annular groove plus three lubrication holes in the outer ring for relubrication. CCK/W33 is the 1:12 tapered-bore counterpart.
Can 23022 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 23022K 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 23022 listed here seats directly on a machined journal.
