How the SL185032 model number is decoded

envelope 160×240×109 mm with a 40.0 mm radial section; every available circumferential space carries a roller because there is no cage C is 930 kN and C0 1610 kN; with a C/C0 ratio of 0.58 the 109 mm-wide full complement concentrates on extreme static and steady radial capacity rather than speed the fatigue load limit Cur is 210 kN, the limiting speed 1,600 r/min and the thermal reference speed 1,030 r/min — full-complement roller-to-roller contact keeps both speeds well below caged cylindrical bearings of the same size the dynamic rating is 5.81 kN per millimetre of the 160 mm bore and 8.53 kN per millimetre of the 109 mm width, figures that explain the use of this bearing in compact, heavily loaded gearbox positions mass is 12.2 kg (12200 g) (0.47 g per mm² of the 240×109 mm envelope); the stiff, thick rings keep raceway deformation low under peak loads at 160 mm bore this is among the largest catalogue sizes; the 1,600 r/min limiting speed confirms a slow-speed, extreme-load application such as a slewing or rolling-mill position SL1850 denotes the double-row full-complement semi-locating bearing: two roller rows share the 160 mm bore, and the arrangement guides the shaft axially in one direction while allowing displacement s in the other Typical applications include marine and offshore winch arrangements, rope drums and winch drums and hydraulic pumps and radial piston pumps, where the 240 mm outside diameter and 930 kN dynamic rating match the duty. In marine and offshore winch arrangements the unit fits a compact 160 mm seat, and in rope drums and winch drums the 12.2 kg mass is part of the rotor inertia calculation. Designers also specify it for hydraulic pumps and radial piston pumps, relying on the 109 mm width and the published 1610 kN static rating. 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. 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.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• 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.
• 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.
• 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.
