How the SL024928 model number is decoded

envelope 140×190×50 mm with a 25.0 mm radial section; every available circumferential space carries a roller because there is no cage C is 270 kN and C0 550 kN; with a C/C0 ratio of 0.49 the 50 mm-wide full complement concentrates on extreme static and steady radial capacity rather than speed the fatigue load limit Cur is 67 kN, the limiting speed 1,950 r/min and the thermal reference speed 1,370 r/min — full-complement roller-to-roller contact keeps both speeds well below caged cylindrical bearings of the same size the dynamic rating is 1.93 kN per millimetre of the 140 mm bore and 5.40 kN per millimetre of the 50 mm width, figures that explain the use of this bearing in compact, heavily loaded gearbox positions mass is 4.1 kg (4100 g) (0.43 g per mm² of the 190×50 mm envelope); the stiff, thick rings keep raceway deformation low under peak loads at 140 mm bore this is among the largest catalogue sizes; the 1,950 r/min limiting speed confirms a slow-speed, extreme-load application such as a slewing or rolling-mill position Shaft and housing shoulders must still locate the rings themselves even though the bearing floats internally; the 25.0 mm section ring is too stiff to self-align At 140 mm bore and 4.1 kg, the SL0249 is specified in rolling-mill gearboxes, travelling mechanisms and construction machinery where thermal shaft growth must not induce thrust Typical applications include crane travelling-wheel mechanisms, compact slow-speed agitator drives and heavy industrial gearbox shafts, where the 190 mm outside diameter and 270 kN dynamic rating match the duty. In crane travelling-wheel mechanisms the unit fits a compact 140 mm seat, and in compact slow-speed agitator drives the 4.1 kg mass is part of the rotor inertia calculation. Designers also specify it for heavy industrial gearbox shafts, relying on the 50 mm width and the published 550 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.
