How the SL192344-TB-BR model number is decoded

envelope 220×460×145 mm with a 120.0 mm radial section; every available circumferential space carries a roller because there is no cage C is 2650 kN and C0 3450 kN; with a C/C0 ratio of 0.77 the 145 mm-wide full complement concentrates on extreme static and steady radial capacity rather than speed the fatigue load limit Cur is 360 kN, the limiting speed 910 r/min and the thermal reference speed 520 r/min — full-complement roller-to-roller contact keeps both speeds well below caged cylindrical bearings of the same size the dynamic rating is 12.05 kN per millimetre of the 220 mm bore and 18.28 kN per millimetre of the 145 mm width, figures that explain the use of this bearing in compact, heavily loaded gearbox positions mass is 111.2 kg (111200 g) (1.67 g per mm² of the 460×145 mm envelope); the stiff, thick rings keep raceway deformation low under peak loads 220 mm bore, 460 mm outside diameter: at this size the 3450 kN C0 rating and rigid full-complement pack replace multi-bearing arrangements in compact heavy-duty designs The 145 mm width versus 460 mm outside diameter gives this series its characteristic squat proportions and high tipping rigidity under eccentric loads 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 -TB marks the TB execution with higher permissible axial load — the improved roller-end/rib lubrication film carries more thrust than the standard full-complement design. BR-finished surfaces tolerate damp assembly environments better than bare steel, which matters for the large 111.2 kg industrial executions. Typical applications include hydraulic pumps and radial piston pumps, marine and offshore winch arrangements and rolling-mill and steel-industry drives, where the 460 mm outside diameter and 2650 kN dynamic rating match the duty. In hydraulic pumps and radial piston pumps the unit fits a compact 220 mm seat, and in marine and offshore winch arrangements the 111.2 kg mass is part of the rotor inertia calculation. Designers also specify it for rolling-mill and steel-industry drives, relying on the 145 mm width and the published 3450 kN static rating. The split outer ring of SL0149 is joined by retaining rings for handling only; never use those rings as a thrust face in the design. 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.

Selection pitfalls — read before you substitute

• The split outer ring of SL0149 is joined by retaining rings for handling only; never use those rings as a thrust face in the design.
• 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.
• C0 is the number that tempts overload in slow machinery, but fatigue life is still governed by the dynamic C rating and lubricant film.
