How the SL192322-TB-XL-BR model number is decoded

envelope 110×240×80 mm with a 65.0 mm radial section; every available circumferential space carries a roller because there is no cage C is 950 kN and C0 970 kN; with a C/C0 ratio of 0.98 the 80 mm-wide full complement concentrates on extreme static and steady radial capacity rather than speed the fatigue load limit Cur is 163 kN, the limiting speed 1,820 r/min and the thermal reference speed 1,270 r/min — full-complement roller-to-roller contact keeps both speeds well below caged cylindrical bearings of the same size the dynamic rating is 8.64 kN per millimetre of the 110 mm bore and 11.88 kN per millimetre of the 80 mm width, figures that explain the use of this bearing in compact, heavily loaded gearbox positions mass is 17 kg (17000 g) (0.89 g per mm² of the 240×80 mm envelope); the stiff, thick rings keep raceway deformation low under peak loads at 110 mm bore the 240 mm outside diameter and 80 mm width target rolling stands, construction machinery and heavy gearboxes; the limiting speed drops to 1,820 r/min SL1923 bearings are semi-locating, with one outer-ring rib and two inner-ring ribs; the wide section delivers extreme C0 — 970 kN at 110 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 The -XL suffix marks the X-life execution: refined raceway topography and upgraded materials lift the basic ratings versus the non-X-life bearing at the same 110×240×80 mm envelope. TB-design bearings use revised roller-end curvature to protect the ribs under combined load — relevant at 110 mm bore where the semi-locating function carries real thrust. -BR marks the oxide-treated execution: the thin black conversion coating protects the 950 kN-rated bearing before it enters lubricated service. Typical applications include crane travelling-wheel mechanisms, compact slow-speed agitator drives and heavy industrial gearbox shafts, where the 240 mm outside diameter and 950 kN dynamic rating match the duty. In crane travelling-wheel mechanisms the unit fits a compact 110 mm seat, and in compact slow-speed agitator drives the 17 kg mass is part of the rotor inertia calculation. Designers also specify it for heavy industrial gearbox shafts, relying on the 80 mm width and the published 970 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.
