How the SL024936 model number is decoded

envelope 180×250×69 mm with a 35.0 mm radial section; every available circumferential space carries a roller because there is no cage C is 570 kN and C0 1200 kN; with a C/C0 ratio of 0.47 the 69 mm-wide full complement concentrates on extreme static and steady radial capacity rather than speed the fatigue load limit Cur is 149 kN, the limiting speed 1,480 r/min and the thermal reference speed 920 r/min — full-complement roller-to-roller contact keeps both speeds well below caged cylindrical bearings of the same size the dynamic rating is 3.17 kN per millimetre of the 180 mm bore and 8.26 kN per millimetre of the 69 mm width, figures that explain the use of this bearing in compact, heavily loaded gearbox positions mass is 10.5 kg (10500 g) (0.61 g per mm² of the 250×69 mm envelope); the stiff, thick rings keep raceway deformation low under peak loads the 180 mm bore puts this execution at the top of the HR1 range — the 250 mm outside diameter, 69 mm width and 10.5 kg mass are built for primary-industry load cases 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 Reading SL0249: the DIN 5412-9 type code family NNCL49 — double row, no cage, flangeless outer ring; the open design is relubricated through groove and holes in the outer ring Typical applications include material handling conveyor pulleys, rolling-mill and steel-industry drives and construction machinery slewing drives, where the 250 mm outside diameter and 570 kN dynamic rating match the duty. In material handling conveyor pulleys the unit fits a compact 180 mm seat, and in rolling-mill and steel-industry drives the 10.5 kg mass is part of the rotor inertia calculation. Designers also specify it for construction machinery slewing drives, relying on the 69 mm width and the published 1200 kN static rating. 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. 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.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• 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.
• 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.
• Relubrication paths matter: specify the annular groove/hole executions where access is poor, because the tightly packed rows trap old grease.
