How the SL185022 model number is decoded

envelope 110×170×80 mm with a 30.0 mm radial section; every available circumferential space carries a roller because there is no cage C is 485 kN and C0 770 kN; with a C/C0 ratio of 0.63 the 80 mm-wide full complement concentrates on extreme static and steady radial capacity rather than speed the fatigue load limit Cur is 111 kN, the limiting speed 2,350 r/min and the thermal reference speed 1,730 r/min — full-complement roller-to-roller contact keeps both speeds well below caged cylindrical bearings of the same size the dynamic rating is 4.41 kN per millimetre of the 110 mm bore and 6.06 kN per millimetre of the 80 mm width, figures that explain the use of this bearing in compact, heavily loaded gearbox positions mass is 6.32 kg (6320 g) (0.46 g per mm² of the 170×80 mm envelope); the stiff, thick rings keep raceway deformation low under peak loads the 110 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 SL1850 denotes the double-row full-complement semi-locating bearing: two roller rows share the 110 mm bore, and the arrangement guides the shaft axially in one direction while allowing displacement s in the other At 6.32 kg (6320 g), this is a rigid machine element used in rolling stands, crane wheels, winches and planetary stages with tight envelope constraints Typical applications include compact slow-speed agitator drives, planetary gear bearing positions and crane travelling-wheel mechanisms, where the 170 mm outside diameter and 485 kN dynamic rating match the duty. In compact slow-speed agitator drives the unit fits a compact 110 mm seat, and in planetary gear bearing positions the 6.32 kg mass is part of the rotor inertia calculation. Designers also specify it for crane travelling-wheel mechanisms, relying on the 80 mm width and the published 770 kN static rating. 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.

Selection pitfalls — read before you substitute

• 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.
• Relubrication paths matter: specify the annular groove/hole executions where access is poor, because the tightly packed rows trap old grease.
