How the 24196 model number is decoded

The 24196 ECA/W33 is a 480×790×308 mm spherical roller bearing — the dimension series 41 (medium OD, maximum width) entry for a 480 mm shaft, with two rows of symmetrical barrel rollers for combined radial and axial load. Digit by digit, 24196 reads as bearing type 2 (spherical roller, two barrel-roller rows), dimension series 41, and bore reference 96 resolving to 480 mm; 790 mm OD and 308 mm width are the matching ISO 15 boundary values. CA executions here use a machined brass cage (ECA enhanced geometry) rather than pressed steel; specialist suffixes change the bearing materially and must be quoted in full, and the K/CCK tapered-bore variant is a separate order number. With C 9198 kN and C0 15600 kN, the 24196 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. The cylindrical-bore execution here seats directly on the shaft journal; if the application calls for an adapter sleeve, order the tapered-bore 24196 CCK30/W33 variant instead and measure the drive-up or clearance reduction, not the nut torque.

Typical equipment & failure modes

Common applications

  • heavy rolling-mill work-roll chocks
  • large dredger and marine winch drums
  • steel-plant continuous-caster segments
  • large induced-draft fan rotors

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

  • At 480 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 24100-series series at 480 mm bore (790×308 mm) is the heaviest medium-OD execution, built for extreme radial and shock loads at low speed; the 400 r/min ceiling is part of the design, not an afterthought — check it before using it in a faster drive.
  • Catalogue reference speed and limiting speed are different limits: the 260 r/min reference is a thermal criterion under load, while the 400 r/min limiting value is the mechanical ceiling — observe both.
  • The 24196 shares its ISO 15 envelope across brands, but internal geometry differs — SKF load ratings in this row are 9198/15600 kN; another maker's same-size bearing may rate higher or lower, so do not interchange on envelope alone.
  • The 9198/15600 kN ratings are SKF catalogue values for this exact execution (24196 ECA/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 24196 (cylindrical bore as listed, tapered-bore 24196 CCK30/W33 variant, plus sealed and vibrating-screen options in the same envelope); they are not interchangeable order numbers — quote the full 24196 ECA/W33 designation when purchasing.

Frequently asked questions

What are the dimensions and catalogue data of 24196?

The 24196 ECA/W33 is a double-row spherical roller bearing with 480 mm bore, 790 mm outer diameter and 308 mm width (18.898 × 31.102 × 12.126 in) per ISO 15. From SKF catalogue PUB BU/P1 17000: basic dynamic load rating C 9198 kN, C0 15600 kN, fatigue load limit Pu 1040 kN, reference speed 260 r/min, limiting speed 400 r/min, mass about 605000 g. It is an open, self-aligning bearing with a one-piece machined brass cage guided on the inner ring (CA design).

How does the 24196 bore code work?

The last two digits of 24196 are bore code 96, so 96 × 5 = 480 mm bore. The 790 mm OD and 308 mm width come from the ISO 15 dimension-series plan (dimension series 41 (medium OD, maximum width)), shared with other spherical roller bearings of the same code.

What does the ECA/W33 suffix mean on 24196?

The suffix ECA/W33 reads ECA — the enhanced version of the CA design with optimized internal geometry, plus W33 (annular groove and three lubrication holes in the outer ring for relubrication); CCK30/W33 is the 1:30 tapered-bore counterpart.

Can 24196 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 24196K30 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 24196 listed here seats directly on a machined journal.
