How the SL024934 model number is decoded

envelope 170×230×60 mm with a 30.0 mm radial section; every available circumferential space carries a roller because there is no cage C is 435 kN and C0 930 kN; with a C/C0 ratio of 0.47 the 60 mm-wide full complement concentrates on extreme static and steady radial capacity rather than speed the fatigue load limit Cur is 116 kN, the limiting speed 1,580 r/min and the thermal reference speed 1,010 r/min — full-complement roller-to-roller contact keeps both speeds well below caged cylindrical bearings of the same size the dynamic rating is 2.56 kN per millimetre of the 170 mm bore and 7.25 kN per millimetre of the 60 mm width, figures that explain the use of this bearing in compact, heavily loaded gearbox positions mass is 7.1 kg (7100 g) (0.51 g per mm² of the 230×60 mm envelope); the stiff, thick rings keep raceway deformation low under peak loads at 170 mm bore this is among the largest catalogue sizes; the 1,580 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 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 planetary gear bearing positions, construction machinery slewing drives and compact slow-speed agitator drives, where the 230 mm outside diameter and 435 kN dynamic rating match the duty. In planetary gear bearing positions the unit fits a compact 170 mm seat, and in construction machinery slewing drives the 7.1 kg mass is part of the rotor inertia calculation. Designers also specify it for compact slow-speed agitator drives, relying on the 60 mm width and the published 930 kN static rating. 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.

Selection pitfalls — read before you substitute

• 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.
• 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.
