How the C4032-V model number is decoded

For long shafts that grow thermally, SKF supplies C 4032 V: the toroidal rollers allow the 160 mm inner ring to displace axially without induced thrust, while still accommodating shaft deflection like a spherical bearing. SKF builds the CARB order number from size plus execution: the bare number C 4032 is the full-complement cylindrical-bore bearing, K (or K30) makes the bore tapered for sleeve mounting, and the cage/seal letters follow — here V. The cylindrical 160 mm bore mounts directly on a machined seat; the outer ring takes a loose housing fit so the bearing can float axially. The same size is listed in both bore executions, and the boundary dimensions 160×240×80 mm are identical — only the mounting method changes. No thermal reference speed is listed for this full-complement execution; the mechanical limiting speed is 600 r/min. The full-complement V executions carry more load but list no thermal reference speed; the steel-caged executions run faster and cooler at light load. Seat tolerances follow the ISO 15 recommendation for the normal-load position — the 240 mm outer ring typically takes a loose housing fit to preserve float, and the rings must be supported across their full faces.

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.
• Envelope-identical spherical roller bearings (same ISO 15 d×D×B) are not drop-in equivalents — they locate the shaft axially, while C 4032 V must float; the two are designed to be used as a pair.
• Never use C 4032 V as the locating bearing: it carries no axial load by design — the arrangement needs a separate locating spherical, tapered or angular bearing facing the thrust.
• 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.
