How the C2244 model number is decoded

C 2244 is a CARB toroidal roller bearing to ISO 15: a single row of long, symmetrical barrel-shaped rollers between guide flanges, sized 220×400×108 mm, as listed in SKF catalogue PUB BU/P1 17000 ch. 10.1. In C 2244 the 22 dimension series fixes the 400 mm OD and 108 mm width around the 220 mm bore (code 44 × 5); the suffix the bare number then selects the cylindrical bore for direct shaft fitting, pressed steel cage. CARB bearings locate neither radially nor axially: the inner ring can walk axially inside the outer ring over the catalogue-listed axial-displacement range (s), so shaft thermal growth disappears as thrust rather than preloading the 220 mm seat. Speed planning separates the 1,500 r/min thermal reference from the 2,000 r/min mechanical limiting speed. 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 heavy-loaded position — the 400 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

• Above 200 mm bore these bearings weigh tens of kilograms (57.5 kg here) — lifting gear and induction heating are mandatory, and a cocked ring scores the toroidal raceway before start-up.
• Reference and limiting speeds are different limits: the 1,500 r/min reference speed is the thermal criterion under load, the limiting value is the mechanical ceiling; observe the reference under load unless the arrangement calculation says otherwise.
• The quoted 2000/2500 kN ratings belong to this exact execution (C 2244); VE240 vibrating-screen variants and sealed 2CS/2NS variants have their own figures even at the same envelope.
• 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.
• Never use C 2244 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.
• The 2000/2500 kN ratings and 57500 g mass are SKF catalogue values transcribed from ch. 10.1 of PUB BU/P1 17000 (PDF table page 864); mounting data — axial displacement (s) and seating details — appears in the running text because the structured record carries the boundary envelope only.
