How the SL182952 model number is decoded

envelope 260×360×60 mm with a 50.0 mm radial section; every available circumferential space carries a roller because there is no cage C is 780 kN and C0 1450 kN; with a C/C0 ratio of 0.54 the 60 mm-wide full complement concentrates on extreme static and steady radial capacity rather than speed the fatigue load limit Cur is 168 kN, the limiting speed 1,020 r/min and the thermal reference speed 690 r/min — full-complement roller-to-roller contact keeps both speeds well below caged cylindrical bearings of the same size the dynamic rating is 3.00 kN per millimetre of the 260 mm bore and 13.00 kN per millimetre of the 60 mm width, figures that explain the use of this bearing in compact, heavily loaded gearbox positions mass is 18.5 kg (18500 g) (0.86 g per mm² of the 360×60 mm envelope); the stiff, thick rings keep raceway deformation low under peak loads 260 mm bore, 360 mm outside diameter: at this size the 1450 kN C0 rating and rigid full-complement pack replace multi-bearing arrangements in compact heavy-duty designs The dimension-series digits place this bearing in the SL18 section of the HR1 plan, giving the 50.0 mm section height between the 260 mm bore and the 360 mm outside diameter 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 marine and offshore winch arrangements, rope drums and winch drums and hydraulic pumps and radial piston pumps, where the 360 mm outside diameter and 780 kN dynamic rating match the duty. In marine and offshore winch arrangements the unit fits a compact 260 mm seat, and in rope drums and winch drums the 18.5 kg mass is part of the rotor inertia calculation. Designers also specify it for hydraulic pumps and radial piston pumps, relying on the 60 mm width and the published 1450 kN static rating. The bearings cannot accommodate angular misalignment; check shaft and housing parallelism before blaming the bearing for edge spalling. C0 is the number that tempts overload in slow machinery, but fatigue life is still governed by the dynamic C rating and lubricant film.

Selection pitfalls — read before you substitute

• The bearings cannot accommodate angular misalignment; check shaft and housing parallelism before blaming the bearing for edge spalling.
• C0 is the number that tempts overload in slow machinery, but fatigue life is still governed by the dynamic C rating and lubricant film.
• 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.
