How the SL192316-XL model number is decoded

envelope 80×170×58 mm with a 45.0 mm radial section; every available circumferential space carries a roller because there is no cage C is 540 kN and C0 560 kN; with a C/C0 ratio of 0.96 the 58 mm-wide full complement concentrates on extreme static and steady radial capacity rather than speed the fatigue load limit Cur is 101 kN, the limiting speed 2,600 r/min and the thermal reference speed 1,820 r/min — full-complement roller-to-roller contact keeps both speeds well below caged cylindrical bearings of the same size the dynamic rating is 6.75 kN per millimetre of the 80 mm bore and 9.31 kN per millimetre of the 58 mm width, figures that explain the use of this bearing in compact, heavily loaded gearbox positions mass is 6.32 kg (6320 g) (0.64 g per mm² of the 170×58 mm envelope); the stiff, thick rings keep raceway deformation low under peak loads at 80 mm bore the 170 mm outside diameter and 58 mm width target rolling stands, construction machinery and heavy gearboxes; the limiting speed drops to 2,600 r/min SL1923 bearings are semi-locating, with one outer-ring rib and two inner-ring ribs; the wide section delivers extreme C0 — 560 kN at 80 mm bore — for slow heavy positions Reading SL1923: full-complement roller set, no cage, self-guided rollers; the wide envelope is chosen where a narrow-section bearing would fit radially but lacks load capacity -XL means this is an X-life bearing — Schaeffler's upgraded performance level with smoother raceways, so the 540 kN C rating and longer nominal life come without an envelope change. Typical applications include heavy industrial gearbox shafts, crane travelling-wheel mechanisms and vibrating and oscillating machinery, where the 170 mm outside diameter and 540 kN dynamic rating match the duty. In heavy industrial gearbox shafts the unit fits a compact 80 mm seat, and in crane travelling-wheel mechanisms the 6.32 kg mass is part of the rotor inertia calculation. Designers also specify it for vibrating and oscillating machinery, relying on the 58 mm width and the published 560 kN static rating. C0 is the number that tempts overload in slow machinery, but fatigue life is still governed by the dynamic C rating and lubricant film. The bearings cannot accommodate angular misalignment; check shaft and housing parallelism before blaming the bearing for edge spalling.

Selection pitfalls — read before you substitute

• C0 is the number that tempts overload in slow machinery, but fatigue life is still governed by the dynamic C rating and lubricant film.
• The bearings cannot accommodate angular misalignment; check shaft and housing parallelism before blaming the bearing for edge spalling.
• Use the rib structure correctly: SL18/SL1850 give one-direction axial guidance, SL0149 locates both ways and SL0249 floats — pairing two locating bearings on one shaft binds thermal growth.
