How the SL024914 model number is decoded

envelope 70×100×30 mm with a 15.0 mm radial section; every available circumferential space carries a roller because there is no cage C is 106 kN and C0 185 kN; with a C/C0 ratio of 0.57 the 30 mm-wide full complement concentrates on extreme static and steady radial capacity rather than speed the fatigue load limit Cur is 27.5 kN, the limiting speed 3,900 r/min and the thermal reference speed 2,330 r/min — full-complement roller-to-roller contact keeps both speeds well below caged cylindrical bearings of the same size the dynamic rating is 1.51 kN per millimetre of the 70 mm bore and 3.53 kN per millimetre of the 30 mm width, figures that explain the use of this bearing in compact, heavily loaded gearbox positions mass is 750 g (0.25 g per mm² of the 100×30 mm envelope); the stiff, thick rings keep raceway deformation low under peak loads with a 70 mm bore this is a heavy-industrial bearing: 750 g of stiff ring and roller set, specified where rigidity matters more than speed Shaft and housing shoulders must still locate the rings themselves even though the bearing floats internally; the 15.0 mm section ring is too stiff to self-align SL0249 is the double-row full-complement non-locating (floating) bearing: the flangeless outer ring moves freely over the rollers, taking only radial load while a separate bearing locates the shaft Typical applications include compact slow-speed agitator drives, planetary gear bearing positions and crane travelling-wheel mechanisms, where the 100 mm outside diameter and 106 kN dynamic rating match the duty. In compact slow-speed agitator drives the unit fits a compact 70 mm seat, and in planetary gear bearing positions the 750 g mass suits the compact, space-optimised housing. Designers also specify it for crane travelling-wheel mechanisms, relying on the 30 mm width and the published 185 kN static rating. Relubrication paths matter: specify the annular groove/hole executions where access is poor, because the tightly packed rows trap old grease. C0 is the number that tempts overload in slow machinery, but fatigue life is still governed by the dynamic C rating and lubricant film.

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.
• C0 is the number that tempts overload in slow machinery, but fatigue life is still governed by the dynamic C rating and lubricant film.
• 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.
