How the 24032 model number is decoded
SKF 24032 (24032 CC/W33) is the spherical-roller choice for a 160 mm shaft — barrel rollers between an inner ring with two raceways and a common sphered outer raceway inside the 240×80 mm ISO 15 envelope. Digit by digit, 24032 reads as bearing type 2 (spherical roller, two barrel-roller rows), dimension series 40, and bore reference 32 resolving to 160 mm; 240 mm OD and 80 mm width are the matching ISO 15 boundary values. 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. Catalogue mass 13000 g for the 160×240×80 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 80 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
- cage pocket wear or fracture from roller skew at insufficient minimum load or rapid acceleration
- roller-end scoring from starved lubricant at start-up before the grease channel purges
- false brinelling on standby machines exposed to external vibration
Selection pitfalls — read before you substitute
- At 160 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 24000-series series at 160 mm bore (240×80 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.
- 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 24032 pits long before its L10 life.
- Never use the tapered-bore CCK30/K30 variant's drive-up figures on this cylindrical-bore 24032; clearance reduction targets differ, and over-driving a cylindrical bore onto an oversized journal cracks the inner ring.
- The 783/1200 kN ratings are SKF catalogue values for this exact execution (24032 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 24032 (cylindrical bore as listed, tapered-bore 24032 CCK30/W33 variant, plus sealed and vibrating-screen options in the same envelope); they are not interchangeable order numbers — quote the full 24032 CC/W33 designation when purchasing.
Frequently asked questions
What are the dimensions and catalogue data of 24032?
The 24032 CC/W33 is a double-row spherical roller bearing with 160 mm bore, 240 mm outer diameter and 80 mm width (6.299 × 9.449 × 3.15 in) per ISO 15. From SKF catalogue PUB BU/P1 17000: basic dynamic load rating C 783 kN, C0 1200 kN, fatigue load limit Pu 114 kN, reference speed 1,700 r/min, limiting speed 2,400 r/min, mass about 13000 g. It is an open, self-aligning bearing with two pressed-steel cages with a floating guide ring.
How does the 24032 bore code work?
The last two digits of 24032 are bore code 32, so 32 × 5 = 160 mm bore. The 240 mm OD and 80 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 24032?
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 24032 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 24032K30 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 24032 listed here seats directly on a machined journal.
