How the SL192326-TB-XL-BR model number is decoded

envelope 130×280×93 mm with a 75.0 mm radial section; every available circumferential space carries a roller because there is no cage C is 1260 kN and C0 1380 kN; with a C/C0 ratio of 0.91 the 93 mm-wide full complement concentrates on extreme static and steady radial capacity rather than speed the fatigue load limit Cur is 225 kN, the limiting speed 1,570 r/min and the thermal reference speed 1,040 r/min — full-complement roller-to-roller contact keeps both speeds well below caged cylindrical bearings of the same size the dynamic rating is 9.69 kN per millimetre of the 130 mm bore and 13.55 kN per millimetre of the 93 mm width, figures that explain the use of this bearing in compact, heavily loaded gearbox positions mass is 27.95 kg (27950 g) (1.07 g per mm² of the 280×93 mm envelope); the stiff, thick rings keep raceway deformation low under peak loads at 130 mm bore this is among the largest catalogue sizes; the 1,570 r/min limiting speed confirms a slow-speed, extreme-load application such as a slewing or rolling-mill position SL1923 bearings are semi-locating, with one outer-ring rib and two inner-ring ribs; the wide section delivers extreme C0 — 1380 kN at 130 mm bore — for slow heavy positions SL192326-TB-XL-BR is the wide dimension-series 23 execution of the single-row full-complement principle: a markedly wider 93 mm ring carries more and longer rollers than the 29/30-series sizes -XL means this is an X-life bearing — Schaeffler's upgraded performance level with smoother raceways, so the 1260 kN C rating and longer nominal life come without an envelope change. Reading -TB: Schaeffler's enhanced-rib design for full-complement bearings; axial friction torque is reduced while radial ratings stay at 1260 kN C. Reading -BR: surface oxide treatment, common on the large TB-design sizes such as this 130 mm-bore bearing; it does not change dimensions or ratings. Typical applications include material handling conveyor pulleys, rolling-mill and steel-industry drives and construction machinery slewing drives, where the 280 mm outside diameter and 1260 kN dynamic rating match the duty. In material handling conveyor pulleys the unit fits a compact 130 mm seat, and in rolling-mill and steel-industry drives the 27.95 kg mass is part of the rotor inertia calculation. Designers also specify it for construction machinery slewing drives, relying on the 93 mm width and the published 1380 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. The bearings cannot accommodate angular misalignment; check shaft and housing parallelism before blaming the bearing for edge spalling.

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.
• The bearings cannot accommodate angular misalignment; check shaft and housing parallelism before blaming the bearing for edge spalling.
• There is no cage: do not apply caged-bearing speed rules — the printed limiting speed is a hard kinematic ceiling set by roller-to-roller contact.
