How the 22328 model number is decoded
For a 140 mm shaft carrying heavy radial load with misalignment or deflection, SKF lists 22328 under catalogue execution 22328 CC/W33: two barrel-roller rows on a sphered outer raceway. The code breaks down as type digit 2 (double-row spherical roller), dimension series 23 (dimension series 23 (heavy OD, wide)), and bore code 28 = 140 mm; dimensions 140×300×102 mm therefore match the ISO 15 envelope. The suffix chain reads CC (two pressed-steel cages with a floating guide ring between the roller rows) plus W33 (annular groove and three lubrication holes in the outer ring for relubrication); CCK/W33 is the 1:12 tapered-bore counterpart. Catalogue mass 36500 g for the 140×300×102 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. For relubrication, route the grease duct to the outer-ring W33 groove position where fitted, and purge until fresh grease appears at the seal — the 102 mm width across two roller rows needs the full charge.
Typical equipment & failure modes
Common applications
- large dredger and marine winch drums
- steel-plant continuous-caster segments
- large induced-draft fan rotors
- SAG and ball-mill drive 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
- roller-end scoring from starved lubricant at start-up before the grease channel purges
- rolling-contact fatigue spalling after the rated L10 life is exceeded
Selection pitfalls — read before you substitute
- At 140 mm bore the ring mass makes cocking during mounting a real risk; guide the bearing square, confirm seat contact around the full circumference, and re-check the self-aligning swing after the housing cap is torqued down.
- The 22300-series series at 140 mm bore (300×102 mm) is the heavy wide-section choice — highest capacity, lowest speed limit; do not substitute a 222 or 230 series in the same bore without re-checking both life and the 2,200 r/min ceiling.
- Shaft and housing fillets must clear the bearing chamfer so the 102 mm-wide rings seat square; use an undercut or withdrawal groove rather than an oversized radius that locks on the ring face.
- Open spherical roller bearings rely on the housing seals; in screening or crusher duty a failed seal lets grit into the sphered raceway and the 22328 pits long before its L10 life.
- The 1357/1560 kN ratings are SKF catalogue values for this exact execution (22328 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 22328 (cylindrical bore as listed, tapered-bore 22328 CCK/W33 variant, plus sealed and vibrating-screen options in the same envelope); they are not interchangeable order numbers — quote the full 22328 CC/W33 designation when purchasing.
Frequently asked questions
What are the dimensions and catalogue data of 22328?
The 22328 CC/W33 is a double-row spherical roller bearing with 140 mm bore, 300 mm outer diameter and 102 mm width (5.512 × 11.811 × 4.016 in) per ISO 15. From SKF catalogue PUB BU/P1 17000: basic dynamic load rating C 1357 kN, C0 1560 kN, fatigue load limit Pu 132 kN, reference speed 1,700 r/min, limiting speed 2,200 r/min, mass about 36500 g. It is an open, self-aligning bearing with two pressed-steel cages with a floating guide ring.
How does the 22328 bore code work?
The last two digits of 22328 are bore code 28, so 28 × 5 = 140 mm bore. The 300 mm OD and 102 mm width come from the ISO 15 dimension-series plan (dimension series 23 (heavy OD, wide)), shared with other spherical roller bearings of the same code.
What does the CC/W33 suffix mean on 22328?
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 22328 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 22328K 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 22328 listed here seats directly on a machined journal.
