How the SL024968 model number is decoded
envelope 340×460×118 mm with a 60.0 mm radial section; every available circumferential space carries a roller because there is no cage C is 1750 kN and C0 4250 kN; with a C/C0 ratio of 0.41 the 118 mm-wide full complement concentrates on extreme static and steady radial capacity rather than speed the fatigue load limit Cur is 450 kN, the limiting speed 770 r/min and the thermal reference speed 375 r/min — full-complement roller-to-roller contact keeps both speeds well below caged cylindrical bearings of the same size the dynamic rating is 5.15 kN per millimetre of the 340 mm bore and 14.83 kN per millimetre of the 118 mm width, figures that explain the use of this bearing in compact, heavily loaded gearbox positions mass is 57.8 kg (57800 g) (1.06 g per mm² of the 460×118 mm envelope); the stiff, thick rings keep raceway deformation low under peak loads 340 mm bore, 460 mm outside diameter: at this size the 4250 kN C0 rating and rigid full-complement pack replace multi-bearing arrangements in compact heavy-duty designs At 340 mm bore and 57.8 kg, the SL0249 is specified in rolling-mill gearboxes, travelling mechanisms and construction machinery where thermal shaft growth must not induce thrust The cageless double pack is speed-limited to 770 r/min (reference 375 r/min) but accepts purely radial loads with the rigidity required in heavy industrial gearboxes Typical applications include planetary gear bearing positions, construction machinery slewing drives and compact slow-speed agitator drives, where the 460 mm outside diameter and 1750 kN dynamic rating match the duty. In planetary gear bearing positions the unit fits a compact 340 mm seat, and in construction machinery slewing drives the 57.8 kg mass is part of the rotor inertia calculation. Designers also specify it for compact slow-speed agitator drives, relying on the 118 mm width and the published 4250 kN static rating. 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. 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
Common applications
- vibrating and oscillating machinery
- planetary gear bearing positions
- rope drums and winch drums
- marine and offshore winch arrangements
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
- 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.
- Relubrication paths matter: specify the annular groove/hole executions where access is poor, because the tightly packed rows trap old grease.
- 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.
Frequently asked questions
What are the dimensions of the SL024968?
The SL024968 is a SL0249 double-row full-complement non-locating cylindrical roller bearing with 460 mm outside diameter, 340 mm bore and 118 mm width, envelope 340×460×118 mm. Mass is 57.8 kg.
What does the SL024968 designation mean in the FAG/INA HR1 catalogue?
SL024968 identifies this SL0249 double-row full-complement non-locating cylindrical roller bearing in the Schaeffler HR1 rolling bearings catalogue. The envelope is 340×460×118 mm and the catalogue ratings are C 1750 kN, C0 4250 kN, Cur 450 kN.
What is the load capacity of the SL024968?
The basic dynamic load rating C is 1750 kN and the basic static load rating C0 is 4250 kN; the fatigue load limit Cur is 450 kN.
What is the maximum speed of the SL024968?
The limiting speed is 770 r/min and the thermal reference speed is 375 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 SL024968?
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.
