How the SL024930 model number is decoded

envelope 150×210×60 mm with a 30.0 mm radial section; every available circumferential space carries a roller because there is no cage C is 410 kN and C0 820 kN; with a C/C0 ratio of 0.50 the 60 mm-wide full complement concentrates on extreme static and steady radial capacity rather than speed the fatigue load limit Cur is 106 kN, the limiting speed 1,790 r/min and the thermal reference speed 1,200 r/min — full-complement roller-to-roller contact keeps both speeds well below caged cylindrical bearings of the same size the dynamic rating is 2.73 kN per millimetre of the 150 mm bore and 6.83 kN per millimetre of the 60 mm width, figures that explain the use of this bearing in compact, heavily loaded gearbox positions mass is 6.45 kg (6450 g) (0.51 g per mm² of the 210×60 mm envelope); the stiff, thick rings keep raceway deformation low under peak loads the 150 mm bore puts this execution at the top of the HR1 range — the 210 mm outside diameter, 60 mm width and 6.45 kg mass are built for primary-industry load cases Two full roller rows give C 410 kN and C0 820 kN in a 210 mm outside diameter — the classic floating position opposite an SL0149 locating bearing The non-locating structure has two inner rings with side ribs and a plain outer ring joined by retaining rings for handling; axial displacement of shaft relative to housing occurs inside the bearing without constraint Typical applications include vibrating and oscillating machinery, heavy industrial gearbox shafts and rope drums and winch drums, where the 210 mm outside diameter and 410 kN dynamic rating match the duty. In vibrating and oscillating machinery the unit fits a compact 150 mm seat, and in heavy industrial gearbox shafts the 6.45 kg mass is part of the rotor inertia calculation. Designers also specify it for rope drums and winch drums, relying on the 60 mm width and the published 820 kN static rating. 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. Use the rib structure correctly: SL18/SL1850 give one-direction axial guidance, SL0149 locates both ways and SL0249 floats — pairing two locating bearings on one shaft binds thermal growth.

Selection pitfalls — read before you substitute

• 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.
• Use the rib structure correctly: SL18/SL1850 give one-direction axial guidance, SL0149 locates both ways and SL0249 floats — pairing two locating bearings on one shaft binds thermal growth.
• The bearings cannot accommodate angular misalignment; check shaft and housing parallelism before blaming the bearing for edge spalling.
