How the SL024976 model number is decoded

envelope 380×520×140 mm with a 70.0 mm radial section; every available circumferential space carries a roller because there is no cage C is 2250 kN and C0 5500 kN; with a C/C0 ratio of 0.41 the 140 mm-wide full complement concentrates on extreme static and steady radial capacity rather than speed the fatigue load limit Cur is 590 kN, the limiting speed 680 r/min and the thermal reference speed 325 r/min — full-complement roller-to-roller contact keeps both speeds well below caged cylindrical bearings of the same size the dynamic rating is 5.92 kN per millimetre of the 380 mm bore and 16.07 kN per millimetre of the 140 mm width, figures that explain the use of this bearing in compact, heavily loaded gearbox positions mass is 90.5 kg (90500 g) (1.24 g per mm² of the 520×140 mm envelope); the stiff, thick rings keep raceway deformation low under peak loads at 380 mm bore this is among the largest catalogue sizes; the 680 r/min limiting speed confirms a slow-speed, extreme-load application such as a slewing or rolling-mill position 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 hydraulic pumps and radial piston pumps, marine and offshore winch arrangements and rolling-mill and steel-industry drives, where the 520 mm outside diameter and 2250 kN dynamic rating match the duty. In hydraulic pumps and radial piston pumps the unit fits a compact 380 mm seat, and in marine and offshore winch arrangements the 90.5 kg mass is part of the rotor inertia calculation. Designers also specify it for rolling-mill and steel-industry drives, relying on the 140 mm width and the published 5500 kN static rating. Press-fit the correct ring: the rotating ring needs interference while the floating ring must slide on its seat to perform the non-locating function. 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

• Press-fit the correct ring: the rotating ring needs interference while the floating ring must slide on its seat to perform the non-locating function.
• 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.
