How the SL192312-XL model number is decoded

envelope 60×130×46 mm with a 35.0 mm radial section; every available circumferential space carries a roller because there is no cage C is 285 kN and C0 275 kN; with a C/C0 ratio of 1.04 the 46 mm-wide full complement concentrates on extreme static and steady radial capacity rather than speed the fatigue load limit Cur is 54 kN, the limiting speed 3,500 r/min and the thermal reference speed 2,480 r/min — full-complement roller-to-roller contact keeps both speeds well below caged cylindrical bearings of the same size the dynamic rating is 4.75 kN per millimetre of the 60 mm bore and 6.20 kN per millimetre of the 46 mm width, figures that explain the use of this bearing in compact, heavily loaded gearbox positions mass is 2.88 kg (2880 g) (0.48 g per mm² of the 130×46 mm envelope); the stiff, thick rings keep raceway deformation low under peak loads at 60 mm bore this is a mainstream industrial size — conveyor drives, winches and medium gearboxes use the 46 mm width as a standard mounting space The separable inner-ring/roller assembly and the single-flanged outer ring allow this bearing to be used as the floating or one-direction-locating position in a two-bearing shaft system Large SL1923 sizes in HR1 are typically the TB design with oxide-finished surfaces; the 2.88 kg mass reflects the thick, deformation-resistant rings As an X-life (-XL) bearing it benefits from the optimised surface finish that reduces friction and raises the fatigue strength behind the 54 kN Cur value. Typical applications include material handling conveyor pulleys, rolling-mill and steel-industry drives and construction machinery slewing drives, where the 130 mm outside diameter and 285 kN dynamic rating match the duty. In material handling conveyor pulleys the unit fits a compact 60 mm seat, and in rolling-mill and steel-industry drives the 2.88 kg mass is part of the rotor inertia calculation. Designers also specify it for construction machinery slewing drives, relying on the 46 mm width and the published 275 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. Relubrication paths matter: specify the annular groove/hole executions where access is poor, because the tightly packed rows trap old grease.

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.
• Relubrication paths matter: specify the annular groove/hole executions where access is poor, because the tightly packed rows trap old grease.
• 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.
