How the SL024938 model number is decoded

envelope 190×260×69 mm with a 35.0 mm radial section; every available circumferential space carries a roller because there is no cage C is 580 kN and C0 1270 kN; with a C/C0 ratio of 0.46 the 69 mm-wide full complement concentrates on extreme static and steady radial capacity rather than speed the fatigue load limit Cur is 155 kN, the limiting speed 1,410 r/min and the thermal reference speed 860 r/min — full-complement roller-to-roller contact keeps both speeds well below caged cylindrical bearings of the same size the dynamic rating is 3.05 kN per millimetre of the 190 mm bore and 8.41 kN per millimetre of the 69 mm width, figures that explain the use of this bearing in compact, heavily loaded gearbox positions mass is 10.9 kg (10900 g) (0.61 g per mm² of the 260×69 mm envelope); the stiff, thick rings keep raceway deformation low under peak loads 190 mm bore, 260 mm outside diameter: at this size the 1270 kN C0 rating and rigid full-complement pack replace multi-bearing arrangements in compact heavy-duty designs The cageless double pack is speed-limited to 1,410 r/min (reference 860 r/min) but accepts purely radial loads with the rigidity required in heavy industrial gearboxes At 190 mm bore and 10.9 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 hydraulic pumps and radial piston pumps, marine and offshore winch arrangements and rolling-mill and steel-industry drives, where the 260 mm outside diameter and 580 kN dynamic rating match the duty. In hydraulic pumps and radial piston pumps the unit fits a compact 190 mm seat, and in marine and offshore winch arrangements the 10.9 kg mass is part of the rotor inertia calculation. Designers also specify it for rolling-mill and steel-industry drives, relying on the 69 mm width and the published 1270 kN static rating. Relubrication paths matter: specify the annular groove/hole executions where access is poor, because the tightly packed rows trap old grease. 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.

Selection pitfalls — read before you substitute

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