How the SL182240 model number is decoded

envelope 200×360×98 mm with a 80.0 mm radial section; every available circumferential space carries a roller because there is no cage C is 1410 kN and C0 2010 kN; with a C/C0 ratio of 0.70 the 98 mm-wide full complement concentrates on extreme static and steady radial capacity rather than speed the fatigue load limit Cur is 245 kN, the limiting speed 1,150 r/min and the thermal reference speed 770 r/min — full-complement roller-to-roller contact keeps both speeds well below caged cylindrical bearings of the same size the dynamic rating is 7.05 kN per millimetre of the 200 mm bore and 14.39 kN per millimetre of the 98 mm width, figures that explain the use of this bearing in compact, heavily loaded gearbox positions mass is 43.12 kg (43120 g) (1.22 g per mm² of the 360×98 mm envelope); the stiff, thick rings keep raceway deformation low under peak loads the 200 mm bore puts this execution at the top of the HR1 range — the 360 mm outside diameter, 98 mm width and 43.12 kg mass are built for primary-industry load cases In the 360 mm envelope the cageless pack raises C0 to 2010 kN; the trade is the 1,150 r/min limiting speed, set by roller-to-roller sliding rather than by a cage The semi-locating function means this bearing locates the shaft in one axial direction and floats in the other — useful in two-bearing shafts where one position is fixed and the other absorbs expansion Typical applications include rope drums and winch drums, vibrating and oscillating machinery and marine and offshore winch arrangements, where the 360 mm outside diameter and 1410 kN dynamic rating match the duty. In rope drums and winch drums the unit fits a compact 200 mm seat, and in vibrating and oscillating machinery the 43.12 kg mass is part of the rotor inertia calculation. Designers also specify it for marine and offshore winch arrangements, relying on the 98 mm width and the published 2010 kN static rating. The split outer ring of SL0149 is joined by retaining rings for handling only; never use those rings as a thrust face in the design. 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.

Selection pitfalls — read before you substitute

• The split outer ring of SL0149 is joined by retaining rings for handling only; never use those rings as a thrust face in the design.
• 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.
• C0 is the number that tempts overload in slow machinery, but fatigue life is still governed by the dynamic C rating and lubricant film.
