How the SL183022 model number is decoded

envelope 110×170×45 mm with a 30.0 mm radial section; every available circumferential space carries a roller because there is no cage C is 280 kN and C0 385 kN; with a C/C0 ratio of 0.73 the 45 mm-wide full complement concentrates on extreme static and steady radial capacity rather than speed the fatigue load limit Cur is 55 kN, the limiting speed 2,350 r/min and the thermal reference speed 2,010 r/min — full-complement roller-to-roller contact keeps both speeds well below caged cylindrical bearings of the same size the dynamic rating is 2.55 kN per millimetre of the 110 mm bore and 6.22 kN per millimetre of the 45 mm width, figures that explain the use of this bearing in compact, heavily loaded gearbox positions mass is 3.5 kg (3500 g) (0.46 g per mm² of the 170×45 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 SL183022 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 The semi-locating function means this bearing locates the shaft in one axial direction and floats in the other — useful in two-bearing shafts where one position is fixed and the other absorbs expansion Typical applications include marine and offshore winch arrangements, rope drums and winch drums and hydraulic pumps and radial piston pumps, where the 170 mm outside diameter and 280 kN dynamic rating match the duty. In marine and offshore winch arrangements the unit fits a compact 110 mm seat, and in rope drums and winch drums the 3.5 kg mass is part of the rotor inertia calculation. Designers also specify it for hydraulic pumps and radial piston pumps, relying on the 45 mm width and the published 385 kN static rating. Relubrication paths matter: specify the annular groove/hole executions where access is poor, because the tightly packed rows trap old grease. 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

• Relubrication paths matter: specify the annular groove/hole executions where access is poor, because the tightly packed rows trap old grease.
• 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.
• Use the rib structure correctly: SL18/SL1850 give one-direction axial guidance, SL0149 locates both ways and SL0249 floats — pairing two locating bearings on one shaft binds thermal growth.
