How the SL024922 model number is decoded

envelope 110×150×40 mm with a 20.0 mm radial section; every available circumferential space carries a roller because there is no cage C is 198 kN and C0 400 kN; with a C/C0 ratio of 0.49 the 40 mm-wide full complement concentrates on extreme static and steady radial capacity rather than speed the fatigue load limit Cur is 51 kN, the limiting speed 2,500 r/min and the thermal reference speed 1,600 r/min — full-complement roller-to-roller contact keeps both speeds well below caged cylindrical bearings of the same size the dynamic rating is 1.80 kN per millimetre of the 110 mm bore and 4.95 kN per millimetre of the 40 mm width, figures that explain the use of this bearing in compact, heavily loaded gearbox positions mass is 2.1 kg (2100 g) (0.35 g per mm² of the 150×40 mm envelope); the stiff, thick rings keep raceway deformation low under peak loads at 110 mm bore the 150 mm outside diameter and 40 mm width target rolling stands, construction machinery and heavy gearboxes; the limiting speed drops to 2,500 r/min At 110 mm bore and 2.1 kg, the SL0249 is specified in rolling-mill gearboxes, travelling mechanisms and construction machinery where thermal shaft growth must not induce thrust 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 rolling-mill and steel-industry drives, hydraulic pumps and radial piston pumps and material handling conveyor pulleys, where the 150 mm outside diameter and 198 kN dynamic rating match the duty. In rolling-mill and steel-industry drives the unit fits a compact 110 mm seat, and in hydraulic pumps and radial piston pumps the 2.1 kg mass is part of the rotor inertia calculation. Designers also specify it for material handling conveyor pulleys, relying on the 40 mm width and the published 400 kN static rating. The bearings cannot accommodate angular misalignment; check shaft and housing parallelism before blaming the bearing for edge spalling. Relubrication paths matter: specify the annular groove/hole executions where access is poor, because the tightly packed rows trap old grease.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• The bearings cannot accommodate angular misalignment; check shaft and housing parallelism before blaming the bearing for edge spalling.
• Relubrication paths matter: specify the annular groove/hole executions where access is poor, because the tightly packed rows trap old grease.
• 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.
