How the SL024940 model number is decoded

envelope 200×280×80 mm with a 40.0 mm radial section; every available circumferential space carries a roller because there is no cage C is 680 kN and C0 1440 kN; with a C/C0 ratio of 0.47 the 80 mm-wide full complement concentrates on extreme static and steady radial capacity rather than speed the fatigue load limit Cur is 176 kN, the limiting speed 1,310 r/min and the thermal reference speed 820 r/min — full-complement roller-to-roller contact keeps both speeds well below caged cylindrical bearings of the same size the dynamic rating is 3.40 kN per millimetre of the 200 mm bore and 8.50 kN per millimetre of the 80 mm width, figures that explain the use of this bearing in compact, heavily loaded gearbox positions mass is 15.3 kg (15300 g) (0.68 g per mm² of the 280×80 mm envelope); the stiff, thick rings keep raceway deformation low under peak loads at 200 mm bore this is among the largest catalogue sizes; the 1,310 r/min limiting speed confirms a slow-speed, extreme-load application such as a slewing or rolling-mill position At 200 mm bore and 15.3 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 material handling conveyor pulleys, rolling-mill and steel-industry drives and construction machinery slewing drives, where the 280 mm outside diameter and 680 kN dynamic rating match the duty. In material handling conveyor pulleys the unit fits a compact 200 mm seat, and in rolling-mill and steel-industry drives the 15.3 kg mass is part of the rotor inertia calculation. Designers also specify it for construction machinery slewing drives, relying on the 80 mm width and the published 1440 kN static rating. Press-fit the correct ring: the rotating ring needs interference while the floating ring must slide on its seat to perform the non-locating function. 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

• Press-fit the correct ring: the rotating ring needs interference while the floating ring must slide on its seat to perform the non-locating function.
• 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.
