How the 24022 model number is decoded
In SKF catalogue PUB BU/P1 17000, 24022 appears as 24022 CC/W33: an open, double-row spherical roller bearing, self-aligning by virtue of the sphered outer raceway, sized 110×170×60 mm to the ISO 15 boundary plan. The code breaks down as type digit 2 (double-row spherical roller), dimension series 40 (dimension series 40 (compact OD, maximum width)), and bore code 22 = 110 mm; dimensions 110×170×60 mm therefore match the ISO 15 envelope. SKF basic executions here are 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. With C 437 kN and C0 620 kN, the 24022 load check covers radial plus moderate axial in either direction — but below the minimum load the rollers skid, so verify P ≥ 0.01·C0 at the lightest operating point. Spherical roller bearings are routinely specified with C3 clearance because the tight inner-ring fit and inner/outer temperature gradient eat into the CN running clearance — check the residual clearance after mounting with feeler gauges.
Typical equipment & failure modes
Common applications
- large vibrating screens and feeders
- marine propulsion and thruster shafts
- cement-mill trunnion and drive shafts
- heavy conveyor head shafts in mining
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
- hard-particle indentation of the raceway in unfiltered oil or contaminated grease systems
Selection pitfalls — read before you substitute
- Mount the 110 mm bore 24022 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 24000-series series at 110 mm bore (170×60 mm) packs maximum roller length into the smallest OD envelope — very high C0 for its size but the lowest speed ceiling; never swap it for a wider-OD 231 bearing without re-checking the housing bore and the speed margin.
- 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.
- The 5000 g mass and 60 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 24022.
- The 437/620 kN ratings are SKF catalogue values for this exact execution (24022 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 24022 (cylindrical bore as listed, tapered-bore 24022 CCK30/W33 variant, plus sealed and vibrating-screen options in the same envelope); they are not interchangeable order numbers — quote the full 24022 CC/W33 designation when purchasing.
Frequently asked questions
What are the dimensions and catalogue data of 24022?
The 24022 CC/W33 is a double-row spherical roller bearing with 110 mm bore, 170 mm outer diameter and 60 mm width (4.331 × 6.693 × 2.362 in) per ISO 15. From SKF catalogue PUB BU/P1 17000: basic dynamic load rating C 437 kN, C0 620 kN, fatigue load limit Pu 67 kN, reference speed 2,400 r/min, limiting speed 3,600 r/min, mass about 5000 g. It is an open, self-aligning bearing with two pressed-steel cages with a floating guide ring.
How does the 24022 bore code work?
The last two digits of 24022 are bore code 22, so 22 × 5 = 110 mm bore. The 170 mm OD and 60 mm width come from the ISO 15 dimension-series plan (dimension series 40 (compact OD, maximum width)), shared with other spherical roller bearings of the same code.
What does the CC/W33 suffix mean on 24022?
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. In dimension series 40/41 the tapered-bore counterpart carries CCK30/W33 with a 1:30 taper.
Can 24022 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 24022K30 variant be used instead?
Choose the K30 (1:30 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 24022 listed here seats directly on a machined journal.
