How the SL024956 model number is decoded

envelope 280×380×100 mm with a 50.0 mm radial section; every available circumferential space carries a roller because there is no cage C is 1150 kN and C0 2650 kN; with a C/C0 ratio of 0.43 the 100 mm-wide full complement concentrates on extreme static and steady radial capacity rather than speed the fatigue load limit Cur is 300 kN, the limiting speed 940 r/min and the thermal reference speed 520 r/min — full-complement roller-to-roller contact keeps both speeds well below caged cylindrical bearings of the same size the dynamic rating is 4.11 kN per millimetre of the 280 mm bore and 11.50 kN per millimetre of the 100 mm width, figures that explain the use of this bearing in compact, heavily loaded gearbox positions mass is 33.1 kg (33100 g) (0.87 g per mm² of the 380×100 mm envelope); the stiff, thick rings keep raceway deformation low under peak loads 280 mm bore, 380 mm outside diameter: at this size the 2650 kN C0 rating and rigid full-complement pack replace multi-bearing arrangements in compact heavy-duty designs 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 Shaft and housing shoulders must still locate the rings themselves even though the bearing floats internally; the 50.0 mm section ring is too stiff to self-align Typical applications include rolling-mill and steel-industry drives, hydraulic pumps and radial piston pumps and material handling conveyor pulleys, where the 380 mm outside diameter and 1150 kN dynamic rating match the duty. In rolling-mill and steel-industry drives the unit fits a compact 280 mm seat, and in hydraulic pumps and radial piston pumps the 33.1 kg mass is part of the rotor inertia calculation. Designers also specify it for material handling conveyor pulleys, relying on the 100 mm width and the published 2650 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. 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.

Typical equipment & failure modes

Common applications

  • marine and offshore winch arrangements
  • crane travelling-wheel mechanisms
  • hydraulic pumps and radial piston pumps
  • rolling-mill and steel-industry drives

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.
  • 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.
  • C0 is the number that tempts overload in slow machinery, but fatigue life is still governed by the dynamic C rating and lubricant film.

Frequently asked questions

What are the dimensions of the SL024956?

The SL024956 is a SL0249 double-row full-complement non-locating cylindrical roller bearing with 380 mm outside diameter, 280 mm bore and 100 mm width, envelope 280×380×100 mm. Mass is 33.1 kg.

What does the SL024956 designation mean in the FAG/INA HR1 catalogue?

SL024956 identifies this SL0249 double-row full-complement non-locating cylindrical roller bearing in the Schaeffler HR1 rolling bearings catalogue. The envelope is 280×380×100 mm and the catalogue ratings are C 1150 kN, C0 2650 kN, Cur 300 kN.

What is the load capacity of the SL024956?

The basic dynamic load rating C is 1150 kN and the basic static load rating C0 is 2650 kN; the fatigue load limit Cur is 300 kN.

What is the maximum speed of the SL024956?

The limiting speed is 940 r/min and the thermal reference speed is 520 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 SL024956?

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.
