How the SL185014-XL model number is decoded

envelope 70×110×54 mm with a 20.0 mm radial section; every available circumferential space carries a roller because there is no cage C is 265 kN and C0 350 kN; with a C/C0 ratio of 0.76 the 54 mm-wide full complement concentrates on extreme static and steady radial capacity rather than speed the fatigue load limit Cur is 60 kN, the limiting speed 3,750 r/min and the thermal reference speed 2,650 r/min — full-complement roller-to-roller contact keeps both speeds well below caged cylindrical bearings of the same size the dynamic rating is 3.79 kN per millimetre of the 70 mm bore and 4.91 kN per millimetre of the 54 mm width, figures that explain the use of this bearing in compact, heavily loaded gearbox positions mass is 1.85 kg (1850 g) (0.31 g per mm² of the 110×54 mm envelope); the stiff, thick rings keep raceway deformation low under peak loads the 70 mm bore belongs to the large band, where HR1 full-complement and track-roller designs deliver their highest kilonewton ratings in slow, heavily loaded machinery Reading SL1850: dimension series 50, double row, no cage; the bearing is supplied with annular lubrication features and is intended for oil or grease lubrication in heavy gearboxes SL1850 denotes the double-row full-complement semi-locating bearing: two roller rows share the 70 mm bore, and the arrangement guides the shaft axially in one direction while allowing displacement s in the other X-life status (-XL) indicates the current Schaeffler premium execution at 70 mm bore; the 350 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 110 mm outside diameter and 265 kN dynamic rating match the duty. In vibrating and oscillating machinery the unit fits a compact 70 mm seat, and in heavy industrial gearbox shafts the 1.85 kg mass is part of the rotor inertia calculation. Designers also specify it for rope drums and winch drums, relying on the 54 mm width and the published 350 kN static rating. 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.

Selection pitfalls — read before you substitute

• 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.
• 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.
