How the SL183013-XL model number is decoded

envelope 65×100×26 mm with a 17.5 mm radial section; every available circumferential space carries a roller because there is no cage C is 130 kN and C0 157 kN; with a C/C0 ratio of 0.83 the 26 mm-wide full complement concentrates on extreme static and steady radial capacity rather than speed the fatigue load limit Cur is 26.5 kN, the limiting speed 4,000 r/min and the thermal reference speed 2,700 r/min — full-complement roller-to-roller contact keeps both speeds well below caged cylindrical bearings of the same size the dynamic rating is 2.00 kN per millimetre of the 65 mm bore and 5.00 kN per millimetre of the 26 mm width, figures that explain the use of this bearing in compact, heavily loaded gearbox positions mass is 730 g (0.28 g per mm² of the 100×26 mm envelope); the stiff, thick rings keep raceway deformation low under peak loads at 65 mm bore the 100 mm outside diameter and 26 mm width target rolling stands, construction machinery and heavy gearboxes; the limiting speed drops to 4,000 r/min 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 SL183013-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 X-life status (-XL) indicates the current Schaeffler premium execution at 65 mm bore; the 157 kN C0 rating reflects the improved rolling-contact geometry. Typical applications include vibrating and oscillating machinery, heavy industrial gearbox shafts and rope drums and winch drums, where the 100 mm outside diameter and 130 kN dynamic rating match the duty. In vibrating and oscillating machinery the unit fits a compact 65 mm seat, and in heavy industrial gearbox shafts the 730 g mass suits the compact, space-optimised housing. Designers also specify it for rope drums and winch drums, relying on the 26 mm width and the published 157 kN static rating. 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. 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.

Selection pitfalls — read before you substitute

• 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.
• 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.
• 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.
