How the SL182913-XL model number is decoded

envelope 65×90×16 mm with a 12.5 mm radial section; every available circumferential space carries a roller because there is no cage C is 67 kN and C0 84 kN; with a C/C0 ratio of 0.80 the 16 mm-wide full complement concentrates on extreme static and steady radial capacity rather than speed the fatigue load limit Cur is 15.4 kN, the limiting speed 4,250 r/min and the thermal reference speed 2,550 r/min — full-complement roller-to-roller contact keeps both speeds well below caged cylindrical bearings of the same size the dynamic rating is 1.03 kN per millimetre of the 65 mm bore and 4.19 kN per millimetre of the 16 mm width, figures that explain the use of this bearing in compact, heavily loaded gearbox positions mass is 310 g (0.22 g per mm² of the 90×16 mm envelope); the stiff, thick rings keep raceway deformation low under peak loads with a 65 mm bore this is a heavy-industrial bearing: 310 g of stiff ring and roller set, specified where rigidity matters more than speed 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 In the 90 mm envelope the cageless pack raises C0 to 84 kN; the trade is the 4,250 r/min limiting speed, set by roller-to-roller sliding rather than by a cage The -XL suffix marks the X-life execution: refined raceway topography and upgraded materials lift the basic ratings versus the non-X-life bearing at the same 65×90×16 mm envelope. Typical applications include construction machinery slewing drives, material handling conveyor pulleys and planetary gear bearing positions, where the 90 mm outside diameter and 67 kN dynamic rating match the duty. In construction machinery slewing drives the unit fits a compact 65 mm seat, and in material handling conveyor pulleys the 310 g mass suits the compact, space-optimised housing. Designers also specify it for planetary gear bearing positions, relying on the 16 mm width and the published 84 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 bearings cannot accommodate angular misalignment; check shaft and housing parallelism before blaming the bearing for edge spalling.

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 bearings cannot accommodate angular misalignment; check shaft and housing parallelism before blaming the bearing for edge spalling.
• 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.
