How the SL182926-XL model number is decoded

envelope 130×180×30 mm with a 25.0 mm radial section; every available circumferential space carries a roller because there is no cage C is 238 kN and C0 350 kN; with a C/C0 ratio of 0.68 the 30 mm-wide full complement concentrates on extreme static and steady radial capacity rather than speed the fatigue load limit Cur is 55 kN, the limiting speed 2,110 r/min and the thermal reference speed 1,500 r/min — full-complement roller-to-roller contact keeps both speeds well below caged cylindrical bearings of the same size the dynamic rating is 1.83 kN per millimetre of the 130 mm bore and 7.93 kN per millimetre of the 30 mm width, figures that explain the use of this bearing in compact, heavily loaded gearbox positions mass is 2.33 kg (2330 g) (0.43 g per mm² of the 180×30 mm envelope); the stiff, thick rings keep raceway deformation low under peak loads 130 mm bore, 180 mm outside diameter: at this size the 350 kN C0 rating and rigid full-complement pack replace multi-bearing arrangements in compact heavy-duty designs SL182926-XL is a single-row full-complement cylindrical roller bearing: no cage is fitted, so the maximum number of rollers runs between the rings, and the rollers guide themselves on the two inner-ring ribs High radial rigidity at 238 kN C is the point of this design: rib-guided rollers in a cageless pack resist deflection in planetary gears, rope drums and vibrating machinery X-life status (-XL) indicates the current Schaeffler premium execution at 130 mm bore; the 350 kN C0 rating reflects the improved rolling-contact geometry. Typical applications include marine and offshore winch arrangements, rope drums and winch drums and hydraulic pumps and radial piston pumps, where the 180 mm outside diameter and 238 kN dynamic rating match the duty. In marine and offshore winch arrangements the unit fits a compact 130 mm seat, and in rope drums and winch drums the 2.33 kg mass is part of the rotor inertia calculation. Designers also specify it for hydraulic pumps and radial piston pumps, relying on the 30 mm width and the published 350 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. 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

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