How the SL185076-TB model number is decoded

envelope 380×560×243 mm with a 90.0 mm radial section; every available circumferential space carries a roller because there is no cage C is 4450 kN and C0 8900 kN; with a C/C0 ratio of 0.50 the 243 mm-wide full complement concentrates on extreme static and steady radial capacity rather than speed the fatigue load limit Cur is 860 kN, the limiting speed 660 r/min and the thermal reference speed 305 r/min — full-complement roller-to-roller contact keeps both speeds well below caged cylindrical bearings of the same size the dynamic rating is 11.71 kN per millimetre of the 380 mm bore and 18.31 kN per millimetre of the 243 mm width, figures that explain the use of this bearing in compact, heavily loaded gearbox positions mass is 196.5 kg (196500 g) (1.44 g per mm² of the 560×243 mm envelope); the stiff, thick rings keep raceway deformation low under peak loads 380 mm bore, 560 mm outside diameter: at this size the 8900 kN C0 rating and rigid full-complement pack replace multi-bearing arrangements in compact heavy-duty designs 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 380 mm bore, and the arrangement guides the shaft axially in one direction while allowing displacement s in the other TB-design bearings use revised roller-end curvature to protect the ribs under combined load — relevant at 380 mm bore where the semi-locating function carries real thrust. Typical applications include rope drums and winch drums, vibrating and oscillating machinery and marine and offshore winch arrangements, where the 560 mm outside diameter and 4450 kN dynamic rating match the duty. In rope drums and winch drums the unit fits a compact 380 mm seat, and in vibrating and oscillating machinery the 196.5 kg mass is part of the rotor inertia calculation. Designers also specify it for marine and offshore winch arrangements, relying on the 243 mm width and the published 8900 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.
