How the SL182226 model number is decoded

envelope 130×230×64 mm with a 50.0 mm radial section; every available circumferential space carries a roller because there is no cage C is 620 kN and C0 850 kN; with a C/C0 ratio of 0.73 the 64 mm-wide full complement concentrates on extreme static and steady radial capacity rather than speed the fatigue load limit Cur is 115 kN, the limiting speed 1,790 r/min and the thermal reference speed 1,360 r/min — full-complement roller-to-roller contact keeps both speeds well below caged cylindrical bearings of the same size the dynamic rating is 4.77 kN per millimetre of the 130 mm bore and 9.69 kN per millimetre of the 64 mm width, figures that explain the use of this bearing in compact, heavily loaded gearbox positions mass is 11.25 kg (11250 g) (0.76 g per mm² of the 230×64 mm envelope); the stiff, thick rings keep raceway deformation low under peak loads at 130 mm bore this is among the largest catalogue sizes; the 1,790 r/min limiting speed confirms a slow-speed, extreme-load application such as a slewing or rolling-mill position Reading the designation: SL18 marks the Schaeffler full-complement semi-locating type with one rib on the outer ring and two ribs on the inner ring; the rollers are axially guided by the inner ring while the outer ring can displace by the catalogue s-value 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 planetary gear bearing positions, construction machinery slewing drives and compact slow-speed agitator drives, where the 230 mm outside diameter and 620 kN dynamic rating match the duty. In planetary gear bearing positions the unit fits a compact 130 mm seat, and in construction machinery slewing drives the 11.25 kg mass is part of the rotor inertia calculation. Designers also specify it for compact slow-speed agitator drives, relying on the 64 mm width and the published 850 kN static rating. C0 is the number that tempts overload in slow machinery, but fatigue life is still governed by the dynamic C rating and lubricant film. The bearings cannot accommodate angular misalignment; check shaft and housing parallelism before blaming the bearing for edge spalling.

Selection pitfalls — read before you substitute

• C0 is the number that tempts overload in slow machinery, but fatigue life is still governed by the dynamic C rating and lubricant film.
• The bearings cannot accommodate angular misalignment; check shaft and housing parallelism before blaming the bearing for edge spalling.
• 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.
