How the C4032-K30V model number is decoded

C 4032 K30V is a CARB toroidal roller bearing to ISO 15: a single row of long, symmetrical barrel-shaped rollers between guide flanges, sized 160×240×80 mm, as listed in SKF catalogue PUB BU/P1 17000 ch. 10.1. The designation C 4032 K30V separates into C (CARB), 40 (dimension series), 32 (160 mm bore) and K30V (tapered 1:30 bore for withdrawal (AH) sleeve mounting, full-complement V execution (no cage)); envelope 160×240×80 mm follows the ISO 15 plan. The K30 suffix gives a 1:30 tapered 160 mm bore, mounted on a withdrawal (AH) sleeve so the bearing can be driven up to the specified clearance. The same size is listed in both bore executions, and the boundary dimensions 160×240×80 mm are identical — only the mounting method changes. Float capacity is a selection criterion: the catalogue lists the permissible axial displacement (s) for the 80 mm wide set; size the free-end housing so thermal growth stays within it, not just inside the overall width. Mounting: mount on the withdrawal (AH) sleeve matched to the 1:30 tapered bore, drive up to the catalogue reduction and lock the nut; never press through the 80 mm roller set, and leave the free-end housing shoulder clear so axial float is unrestricted.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• At 160 mm bore, shaft expansion is already measurable: calculate the required float inside the 80 mm wide bearing rather than assuming the free-end clearance is "enough" at operating temperature.
• Do not block the axial displacement in the drawing: housing covers, labyrinth rings and snap rings must leave the catalogue float (s) free, or the bearing silently becomes a poorly located fixed bearing.
• Envelope-identical spherical roller bearings (same ISO 15 d×D×B) are not drop-in equivalents — they locate the shaft axially, while C 4032 K30V must float; the two are designed to be used as a pair.
• Tapered-bore K executions mount on adapter sleeves (1:12) and K30 on withdrawal sleeves (1:30) — the 160 mm bore changes the sleeve family, and the drive-up procedure differs accordingly.
• Reference and limiting speeds are different limits: the catalogue lists no thermal reference speed for this full-complement/sealed execution, the limiting value is the mechanical ceiling; observe the reference under load unless the arrangement calculation says otherwise.
• The 915/1460 kN ratings and 13000 g mass are SKF catalogue values transcribed from ch. 10.1 of PUB BU/P1 17000 (PDF table page 862); mounting data — axial displacement (s) and seating details — appears in the running text because the structured record carries the boundary envelope only.
