How the SL024980 model number is decoded

envelope 400×540×140 mm with a 70.0 mm radial section; every available circumferential space carries a roller because there is no cage C is 2310 kN and C0 5800 kN; with a C/C0 ratio of 0.40 the 140 mm-wide full complement concentrates on extreme static and steady radial capacity rather than speed the fatigue load limit Cur is 610 kN, the limiting speed 650 r/min and the thermal reference speed 300 r/min — full-complement roller-to-roller contact keeps both speeds well below caged cylindrical bearings of the same size the dynamic rating is 5.78 kN per millimetre of the 400 mm bore and 16.50 kN per millimetre of the 140 mm width, figures that explain the use of this bearing in compact, heavily loaded gearbox positions mass is 94.6 kg (94600 g) (1.25 g per mm² of the 540×140 mm envelope); the stiff, thick rings keep raceway deformation low under peak loads at 400 mm bore this is among the largest catalogue sizes; the 650 r/min limiting speed confirms a slow-speed, extreme-load application such as a slewing or rolling-mill position 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 The cageless double pack is speed-limited to 650 r/min (reference 300 r/min) but accepts purely radial loads with the rigidity required in heavy industrial gearboxes Typical applications include marine and offshore winch arrangements, rope drums and winch drums and hydraulic pumps and radial piston pumps, where the 540 mm outside diameter and 2310 kN dynamic rating match the duty. In marine and offshore winch arrangements the unit fits a compact 400 mm seat, and in rope drums and winch drums the 94.6 kg mass is part of the rotor inertia calculation. Designers also specify it for hydraulic pumps and radial piston pumps, relying on the 140 mm width and the published 5800 kN static rating. 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.

Typical equipment & failure modes

Common applications

  • crane travelling-wheel mechanisms
  • material handling conveyor pulleys
  • heavy industrial gearbox shafts
  • vibrating and oscillating machinery

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

  • 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.
  • 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 SL024980?

The SL024980 is a SL0249 double-row full-complement non-locating cylindrical roller bearing with 540 mm outside diameter, 400 mm bore and 140 mm width, envelope 400×540×140 mm. Mass is 94.6 kg.

What does the SL024980 designation mean in the FAG/INA HR1 catalogue?

SL024980 identifies this SL0249 double-row full-complement non-locating cylindrical roller bearing in the Schaeffler HR1 rolling bearings catalogue. The envelope is 400×540×140 mm and the catalogue ratings are C 2310 kN, C0 5800 kN, Cur 610 kN.

What is the load capacity of the SL024980?

The basic dynamic load rating C is 2310 kN and the basic static load rating C0 is 5800 kN; the fatigue load limit Cur is 610 kN.

What is the maximum speed of the SL024980?

The limiting speed is 650 r/min and the thermal reference speed is 300 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 SL024980?

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.
