How the SL024952 model number is decoded
envelope 260×360×100 mm with a 50.0 mm radial section; every available circumferential space carries a roller because there is no cage C is 1100 kN and C0 2470 kN; with a C/C0 ratio of 0.45 the 100 mm-wide full complement concentrates on extreme static and steady radial capacity rather than speed the fatigue load limit Cur is 285 kN, the limiting speed 1,010 r/min and the thermal reference speed 570 r/min — full-complement roller-to-roller contact keeps both speeds well below caged cylindrical bearings of the same size the dynamic rating is 4.23 kN per millimetre of the 260 mm bore and 11.00 kN per millimetre of the 100 mm width, figures that explain the use of this bearing in compact, heavily loaded gearbox positions mass is 31.2 kg (31200 g) (0.87 g per mm² of the 360×100 mm envelope); the stiff, thick rings keep raceway deformation low under peak loads at 260 mm bore this is among the largest catalogue sizes; the 1,010 r/min limiting speed confirms a slow-speed, extreme-load application such as a slewing or rolling-mill position 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 compact slow-speed agitator drives, planetary gear bearing positions and crane travelling-wheel mechanisms, where the 360 mm outside diameter and 1100 kN dynamic rating match the duty. In compact slow-speed agitator drives the unit fits a compact 260 mm seat, and in planetary gear bearing positions the 31.2 kg mass is part of the rotor inertia calculation. Designers also specify it for crane travelling-wheel mechanisms, relying on the 100 mm width and the published 2470 kN static rating. 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 bearings cannot accommodate angular misalignment; check shaft and housing parallelism before blaming the bearing for edge spalling.
Typical equipment & failure modes
Common applications
- hydraulic pumps and radial piston pumps
- heavy industrial gearbox shafts
- rolling-mill and steel-industry drives
- material handling conveyor pulleys
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
- 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 bearings cannot accommodate angular misalignment; check shaft and housing parallelism before blaming the bearing for edge spalling.
- 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.
Frequently asked questions
What are the dimensions of the SL024952?
The SL024952 is a SL0249 double-row full-complement non-locating cylindrical roller bearing with 360 mm outside diameter, 260 mm bore and 100 mm width, envelope 260×360×100 mm. Mass is 31.2 kg.
What does the SL024952 designation mean in the FAG/INA HR1 catalogue?
SL024952 identifies this SL0249 double-row full-complement non-locating cylindrical roller bearing in the Schaeffler HR1 rolling bearings catalogue. The envelope is 260×360×100 mm and the catalogue ratings are C 1100 kN, C0 2470 kN, Cur 285 kN.
What is the load capacity of the SL024952?
The basic dynamic load rating C is 1100 kN and the basic static load rating C0 is 2470 kN; the fatigue load limit Cur is 285 kN.
What is the maximum speed of the SL024952?
The limiting speed is 1,010 r/min and the thermal reference speed is 570 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 SL024952?
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.
