How the SL024924 model number is decoded
envelope 120×165×45 mm with a 22.5 mm radial section; every available circumferential space carries a roller because there is no cage C is 222 kN and C0 440 kN; with a C/C0 ratio of 0.50 the 45 mm-wide full complement concentrates on extreme static and steady radial capacity rather than speed the fatigue load limit Cur is 56 kN, the limiting speed 2,260 r/min and the thermal reference speed 1,540 r/min — full-complement roller-to-roller contact keeps both speeds well below caged cylindrical bearings of the same size the dynamic rating is 1.85 kN per millimetre of the 120 mm bore and 4.93 kN per millimetre of the 45 mm width, figures that explain the use of this bearing in compact, heavily loaded gearbox positions mass is 2.85 kg (2850 g) (0.38 g per mm² of the 165×45 mm envelope); the stiff, thick rings keep raceway deformation low under peak loads the 120 mm bore belongs to the large band, where HR1 full-complement and track-roller designs deliver their highest kilonewton ratings in slow, heavily loaded machinery The cageless double pack is speed-limited to 2,260 r/min (reference 1,540 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 marine and offshore winch arrangements, rope drums and winch drums and hydraulic pumps and radial piston pumps, where the 165 mm outside diameter and 222 kN dynamic rating match the duty. In marine and offshore winch arrangements the unit fits a compact 120 mm seat, and in rope drums and winch drums the 2.85 kg mass is part of the rotor inertia calculation. Designers also specify it for hydraulic pumps and radial piston pumps, relying on the 45 mm width and the published 440 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
- planetary gear bearing positions
- hydraulic pumps and radial piston pumps
- compact slow-speed agitator drives
- crane travelling-wheel mechanisms
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 SL024924?
The SL024924 is a SL0249 double-row full-complement non-locating cylindrical roller bearing with 165 mm outside diameter, 120 mm bore and 45 mm width, envelope 120×165×45 mm. Mass is 2.85 kg.
What does the SL024924 designation mean in the FAG/INA HR1 catalogue?
SL024924 identifies this SL0249 double-row full-complement non-locating cylindrical roller bearing in the Schaeffler HR1 rolling bearings catalogue. The envelope is 120×165×45 mm and the catalogue ratings are C 222 kN, C0 440 kN, Cur 56 kN.
What is the load capacity of the SL024924?
The basic dynamic load rating C is 222 kN and the basic static load rating C0 is 440 kN; the fatigue load limit Cur is 56 kN.
What is the maximum speed of the SL024924?
The limiting speed is 2,260 r/min and the thermal reference speed is 1,540 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 SL024924?
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.
