How the SL024944 model number is decoded

envelope 220×300×80 mm with a 40.0 mm radial section; every available circumferential space carries a roller because there is no cage C is 700 kN and C0 1550 kN; with a C/C0 ratio of 0.45 the 80 mm-wide full complement concentrates on extreme static and steady radial capacity rather than speed the fatigue load limit Cur is 185 kN, the limiting speed 1,220 r/min and the thermal reference speed 750 r/min — full-complement roller-to-roller contact keeps both speeds well below caged cylindrical bearings of the same size the dynamic rating is 3.18 kN per millimetre of the 220 mm bore and 8.75 kN per millimetre of the 80 mm width, figures that explain the use of this bearing in compact, heavily loaded gearbox positions mass is 16.7 kg (16700 g) (0.70 g per mm² of the 300×80 mm envelope); the stiff, thick rings keep raceway deformation low under peak loads 220 mm bore, 300 mm outside diameter: at this size the 1550 kN C0 rating and rigid full-complement pack replace multi-bearing arrangements in compact heavy-duty designs SL0249 is the double-row full-complement non-locating (floating) bearing: the flangeless outer ring moves freely over the rollers, taking only radial load while a separate bearing locates the shaft Shaft and housing shoulders must still locate the rings themselves even though the bearing floats internally; the 40.0 mm section ring is too stiff to self-align Typical applications include rope drums and winch drums, vibrating and oscillating machinery and marine and offshore winch arrangements, where the 300 mm outside diameter and 700 kN dynamic rating match the duty. In rope drums and winch drums the unit fits a compact 220 mm seat, and in vibrating and oscillating machinery the 16.7 kg mass is part of the rotor inertia calculation. Designers also specify it for marine and offshore winch arrangements, relying on the 80 mm width and the published 1550 kN static rating. 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. 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.

Selection pitfalls — read before you substitute

• 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.
• 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.
• C0 is the number that tempts overload in slow machinery, but fatigue life is still governed by the dynamic C rating and lubricant film.
