How the SL182236 model number is decoded

envelope 180×320×86 mm with a 70.0 mm radial section; every available circumferential space carries a roller because there is no cage C is 1180 kN and C0 1760 kN; with a C/C0 ratio of 0.67 the 86 mm-wide full complement concentrates on extreme static and steady radial capacity rather than speed the fatigue load limit Cur is 218 kN, the limiting speed 1,230 r/min and the thermal reference speed 800 r/min — full-complement roller-to-roller contact keeps both speeds well below caged cylindrical bearings of the same size the dynamic rating is 6.56 kN per millimetre of the 180 mm bore and 13.72 kN per millimetre of the 86 mm width, figures that explain the use of this bearing in compact, heavily loaded gearbox positions mass is 29.8 kg (29800 g) (1.08 g per mm² of the 320×86 mm envelope); the stiff, thick rings keep raceway deformation low under peak loads 180 mm bore, 320 mm outside diameter: at this size the 1760 kN C0 rating and rigid full-complement pack replace multi-bearing arrangements in compact heavy-duty designs Reading the designation: SL18 marks the Schaeffler full-complement semi-locating type with one rib on the outer ring and two ribs on the inner ring; the rollers are axially guided by the inner ring while the outer ring can displace by the catalogue s-value In the 320 mm envelope the cageless pack raises C0 to 1760 kN; the trade is the 1,230 r/min limiting speed, set by roller-to-roller sliding rather than by a cage Typical applications include rope drums and winch drums, vibrating and oscillating machinery and marine and offshore winch arrangements, where the 320 mm outside diameter and 1180 kN dynamic rating match the duty. In rope drums and winch drums the unit fits a compact 180 mm seat, and in vibrating and oscillating machinery the 29.8 kg mass is part of the rotor inertia calculation. Designers also specify it for marine and offshore winch arrangements, relying on the 86 mm width and the published 1760 kN static rating. Relubrication paths matter: specify the annular groove/hole executions where access is poor, because the tightly packed rows trap old grease. The bearings cannot accommodate angular misalignment; check shaft and housing parallelism before blaming the bearing for edge spalling.

Typical equipment & failure modes

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.
• The bearings cannot accommodate angular misalignment; check shaft and housing parallelism before blaming the bearing for edge spalling.
• 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.
