How the SL182919-XL model number is decoded

envelope 95×130×22 mm with a 17.5 mm radial section; every available circumferential space carries a roller because there is no cage C is 132 kN and C0 177 kN; with a C/C0 ratio of 0.75 the 22 mm-wide full complement concentrates on extreme static and steady radial capacity rather than speed the fatigue load limit Cur is 28 kN, the limiting speed 2,950 r/min and the thermal reference speed 1,940 r/min — full-complement roller-to-roller contact keeps both speeds well below caged cylindrical bearings of the same size the dynamic rating is 1.39 kN per millimetre of the 95 mm bore and 6.00 kN per millimetre of the 22 mm width, figures that explain the use of this bearing in compact, heavily loaded gearbox positions mass is 860 g (0.30 g per mm² of the 130×22 mm envelope); the stiff, thick rings keep raceway deformation low under peak loads at 95 mm bore the 130 mm outside diameter and 22 mm width target rolling stands, construction machinery and heavy gearboxes; the limiting speed drops to 2,950 r/min High radial rigidity at 132 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 SL18 bearings are separable for mounting: the inner ring with the self-retained roller set can be fitted separately from the plain-bored outer ring, which simplifies interference-fit assembly X-life status (-XL) indicates the current Schaeffler premium execution at 95 mm bore; the 177 kN C0 rating reflects the improved rolling-contact geometry. Typical applications include crane travelling-wheel mechanisms, compact slow-speed agitator drives and heavy industrial gearbox shafts, where the 130 mm outside diameter and 132 kN dynamic rating match the duty. In crane travelling-wheel mechanisms the unit fits a compact 95 mm seat, and in compact slow-speed agitator drives the 860 g mass suits the compact, space-optimised housing. Designers also specify it for heavy industrial gearbox shafts, relying on the 22 mm width and the published 177 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. Relubrication paths matter: specify the annular groove/hole executions where access is poor, because the tightly packed rows trap old grease.

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.
• Relubrication paths matter: specify the annular groove/hole executions where access is poor, because the tightly packed rows trap old grease.
• Press-fit the correct ring: the rotating ring needs interference while the floating ring must slide on its seat to perform the non-locating function.
