How the SL182219 model number is decoded

envelope 95×170×43 mm with a 37.5 mm radial section; every available circumferential space carries a roller because there is no cage C is 330 kN and C0 425 kN; with a C/C0 ratio of 0.78 the 43 mm-wide full complement concentrates on extreme static and steady radial capacity rather than speed the fatigue load limit Cur is 62 kN, the limiting speed 2,420 r/min and the thermal reference speed 1,780 r/min — full-complement roller-to-roller contact keeps both speeds well below caged cylindrical bearings of the same size the dynamic rating is 3.47 kN per millimetre of the 95 mm bore and 7.67 kN per millimetre of the 43 mm width, figures that explain the use of this bearing in compact, heavily loaded gearbox positions mass is 4.17 kg (4170 g) (0.57 g per mm² of the 170×43 mm envelope); the stiff, thick rings keep raceway deformation low under peak loads the 95 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 In the 170 mm envelope the cageless pack raises C0 to 425 kN; the trade is the 2,420 r/min limiting speed, set by roller-to-roller sliding rather than by a cage The dimension-series digits place this bearing in the SL18 section of the HR1 plan, giving the 37.5 mm section height between the 95 mm bore and the 170 mm outside diameter Typical applications include heavy industrial gearbox shafts, crane travelling-wheel mechanisms and vibrating and oscillating machinery, where the 170 mm outside diameter and 330 kN dynamic rating match the duty. In heavy industrial gearbox shafts the unit fits a compact 95 mm seat, and in crane travelling-wheel mechanisms the 4.17 kg mass is part of the rotor inertia calculation. Designers also specify it for vibrating and oscillating machinery, relying on the 43 mm width and the published 425 kN static rating. Relubrication paths matter: specify the annular groove/hole executions where access is poor, because the tightly packed rows trap old grease. 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

• Relubrication paths matter: specify the annular groove/hole executions where access is poor, because the tightly packed rows trap old grease.
• 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.
• C0 is the number that tempts overload in slow machinery, but fatigue life is still governed by the dynamic C rating and lubricant film.
