How the SL024948 model number is decoded
envelope 240×320×80 mm with a 40.0 mm radial section; every available circumferential space carries a roller because there is no cage C is 740 kN and C0 1700 kN; with a C/C0 ratio of 0.44 the 80 mm-wide full complement concentrates on extreme static and steady radial capacity rather than speed the fatigue load limit Cur is 198 kN, the limiting speed 1,110 r/min and the thermal reference speed 660 r/min — full-complement roller-to-roller contact keeps both speeds well below caged cylindrical bearings of the same size the dynamic rating is 3.08 kN per millimetre of the 240 mm bore and 9.25 kN per millimetre of the 80 mm width, figures that explain the use of this bearing in compact, heavily loaded gearbox positions mass is 17.9 kg (17900 g) (0.70 g per mm² of the 320×80 mm envelope); the stiff, thick rings keep raceway deformation low under peak loads the 240 mm bore puts this execution at the top of the HR1 range — the 320 mm outside diameter, 80 mm width and 17.9 kg mass are built for primary-industry load cases The cageless double pack is speed-limited to 1,110 r/min (reference 660 r/min) but accepts purely radial loads with the rigidity required in heavy industrial gearboxes 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 compact slow-speed agitator drives, planetary gear bearing positions and crane travelling-wheel mechanisms, where the 320 mm outside diameter and 740 kN dynamic rating match the duty. In compact slow-speed agitator drives the unit fits a compact 240 mm seat, and in planetary gear bearing positions the 17.9 kg mass is part of the rotor inertia calculation. Designers also specify it for crane travelling-wheel mechanisms, relying on the 80 mm width and the published 1700 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. 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.
Typical equipment & failure modes
Common applications
- rope drums and winch drums
- compact slow-speed agitator drives
- marine and offshore winch arrangements
- hydraulic pumps and radial piston pumps
Known failure patterns
- raceway pitting from overloaded slow-speed positions where the cageless rollers repeatedly stress one contact band
- rib and roller-end scoring when applied axial thrust exceeds the semi-locating capacity
- roller smearing from roller-to-roller sliding at speeds above the limiting value
- edge loading and premature spalling caused by undetected shaft/housing misalignment (full-complement rows cannot self-align)
- brinelling of the raceways from static shock during mounting or transport of the heavy rotor
- lubricant starvation in the tightly packed roller set, especially in the double-row executions
- freting and creep on a loose ring seat under a rotating load
- contamination wear in open gearbox positions with damaged seals or breathers
- false brinelling from micro-movement while the shaft is stationary under vibration
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.
- 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.
Frequently asked questions
What are the dimensions of the SL024948?
The SL024948 is a SL0249 double-row full-complement non-locating cylindrical roller bearing with 320 mm outside diameter, 240 mm bore and 80 mm width, envelope 240×320×80 mm. Mass is 17.9 kg.
What does the SL024948 designation mean in the FAG/INA HR1 catalogue?
SL024948 identifies this SL0249 double-row full-complement non-locating cylindrical roller bearing in the Schaeffler HR1 rolling bearings catalogue. The envelope is 240×320×80 mm and the catalogue ratings are C 740 kN, C0 1700 kN, Cur 198 kN.
What is the load capacity of the SL024948?
The basic dynamic load rating C is 740 kN and the basic static load rating C0 is 1700 kN; the fatigue load limit Cur is 198 kN.
What is the maximum speed of the SL024948?
The limiting speed is 1,110 r/min and the thermal reference speed is 660 r/min. In the Schaeffler catalogue the reference speed is the thermally permissible running speed under defined load; the lower of the two values governs each application.
What is the locating function of the SL024948?
The SL0249 is non-locating: the flangeless outer ring floats freely and takes radial load only, making it the standard partner for a locating SL0149.
